“Yeah she threw a rod” had me rolling 😂 thanks for the laugh
Eric, I've sat in 100's of those design review meetings over the past 40 year as a design engineer. It usually goes like this...
Engineer: "We're going to use a 6mm hex head screw, it's a common size"
Purchasing Bean Counter: "We can get 5.5mm hex head screws $0.001 cheaper"
Boss to Engineer: "Change it!"
You need to whack the bean counter over his 'computer' to give him a reboot.
I can’t believe I just needed to order a 5.5 deep and 5.5 wobble to remove the ignition assembly thinger I in my Ford Escape. Does a socket set come standard with a 5.5? Nope. So Ford must be collaborating with socket manufacturers to sell 5.5s. Or not
100%
@@marksd5650 not just Ford, I remember Saturn also used a 5.5mm socket for its ignition switch
Just use a 7/32 I've yet to purchase a 5.5 never had an issue
You're killin' it lately, Eric! Spoiling us with all these videos.
Totally agree it's been brilliant 👍
I agree I needed ole Eric when I was young and dumb!! Ha Ha Still dumb!!
Find one thing broke and hope you got it. Find a second thing broke and know you got it. Now that's how most of my projects go. Reality at South Main Auto, gotta love it.
Mechanics have it so easy these days. I spent Sept 1970-May 1974 in the Oldsmobile final assembly plant in Lansing Michigan. It was a hoot watching my co-workers assembling the dash. It was face down on a special support, and they had free access to everything from any direction. To assemble the dash they use custom-made tools to snake wires, and cables through the rats nest. Thus, even if your mechanic pulled the dash completely out of the car, they would never ever be able to complete some repairs without those special tools. I will bet only the dealers had access to those special tools. But I don't know.
A 2005 Nissan Xterra was my first vehicle... bought it used with 230,000km for $1,000 CAD. Same red colour. I loved that beast: learned so much about automotive mechanics and general car care/repair. Drove it for 5 years and ended up putting it to rest at 400,000km. The blower motor was one of the first repairs I ever did. Thanks for the memories, Mr. O!
Lesson learned: "Test both the resistor and the blower motor"
It took me a moment to appreciate the Fonz quote, ha ha ha. The way he would bump the soda machine and get a drink was legend. Most guys who watch here weren't born yet.
I was thinking the same thing, lol
I remember watching reruns of Happy Days when I was a kid. Im almost 40.
Throughout my career as a master technician with Ford, Lincoln and Mercury I always sold the blower resistor and blower motor assembly together. It’s an excellent insurance policy.
"Threw a rod" made me laugh. I like your chatter.
I love your comedy while you work. I love your bashing of auto engineers. 😀👍. Bob. From Florida
I love my SMA hoodie. Warm and I’m flying the colors!! Get one today!!
Thanks Eric for a great video. We know it takes time to make them, and I’m pretty dang sure we all appreciate your efforts.
Be safe. And Cheers!!
You're awesome. You made a 25 minute video about a heater fan and it's highly entertaining.
I have to say out of all the videos I’ve watched about fixing something on the Fritz with my xterra this one has by far been my fav
Be careful on Fonzie! This younger generation does not know anything about Happy Days 😂😂🤣🤣
Fonzie - Henry Winkler - is 76 years old now.
Da Fonz does not grow old! Ayyyyyyhhhhhh!
@@flagmichael did you know his full name was Arthur HERBERT Fonzarelli. I had no idea his middle name and I don't recall it ever used in the 255 (11 years) episodes
Thank goodness for winter time more SMA videos for your viewing pleasure
Always a good day to see you figure it out, twice…haha. It needed all three changed out and you knew it.
Once again a great class for us DIY guys Eric. I channeled you the other day when I used my meter and power probe to assess why my "speed control" which is what Ford calls the cruise control on my mint 2001 F-250 Superduty 7.3 was not working. I traced it down to a crusty plug connector on the master cylinder switch. Removed it, cleaned it up with CRC Electrical Connector cleaner, tested the two 2 amp inline fuses (this was a recall replacement fused jumper harness). Fuse #28 was good, I watched your 2015 video on clock springs. Ran through all; the other possibilities like power and grounds, horn function, speedometer function, rear ABS speed sensor (no ABS light illuminated) No air bag check light illuminated etc. Decided it was the cruddy plug. Problem fixed. I was about to do the clock spring dance... no. need as the cruise control came right up as commanded and all the other steering wheel controls were working normally. Thanks Eric for all you do for us. You are at the top of my list of favorite UA-cam Instructors. You are entertaining, your wife is a wonderful lady and your filming and editing along with your instruction are first rate. I live on the other side of the continent in WA State. Otherwise I would bring my vehicles to you for things beyond my level. It would be fun to talk to you face to face sometime and thank you in person for all your videos. Please keep the videos coming as they are invaluable. An honest quality mechanic can be a hard thing to find. I had one but colon cancer took him away early in his mid 40's. I miss Mike very much.He was honest and talented to a fault. Now it's me with your tutelage. I'm even making my own how to videos as well. Thanks again Eric. Oh... and I am wearing out my SMA Hoodie. :0)
Read the title too quick though we were in for a BLOWN motor 😂
I feel your pain from the gut feeling. To get paid for actual diag time is almost impossible in my neighborhood. One shop I worked at always sold the resistor and blower as a combo. Truth be told, I didn't mind. I hate just throwing parts at cars, but being under most dashboards is difficult. I'm a big guy with broad shoulders, I don't fit well under most dashboards. I also have had my neck bones rebuilt. If I'm going under, I don't mind replacing them both. As always, your videos are my top clicks. I only watch other channels if the repair is relevant to something im working on. Just know alot of us was feeling the pain of being crammed under there.
I'm sure Eric is thankful he's not a big guy as I think he's at most 5'10" and wears a medium to large shirt/hoodie, so even then, it's tight under there and I've had to deal with being under my dashboard and yes, it's no fun at tall for anyone, but more so for the bigger guys, especially the more broad shouldered, barrel chested ones.
Yes, Eric O., that's exactly how it went down! The birth of the 5.5mm socket finally explained.
With a PWM signal, that "resistor" was likely a power transistor. Usually, power transitors have an inline thermal fuse that blows. Replaced one on a 2004 Honda Pilot. No where in the manual did they tell you about the fine mesh over the blower intake that was in the driver's footwell. Previous owner had had small dogs, so there was a felt built up over the intake.
Couldn't understand why a PWM driven motor would need a big-ass resistor. Thanks for the comment.
@Bret Agreed, and I still wonder why a transistor that should be saturating would need a heatsink that huge (30W?)
Exactly. And 99/100 a power transistor is going to fail short . Which is to say the blower will be full on. If it's not, then go looking for that thermal fuse if you have the time. If you don't have the time and it's not your car, follow Eric's path of replacing the parts.
That's nuts!
I take it you mean a non reset-able thermal fuse on the heatsink?
Either way, the only purpose of that would be to protect the mosfet from getting too hot. Why bother if the thermal fuse is just going to disable the PWM driver anyway?
Some designs man, really make you wonder.
If it were my car, I'd build a board with a fet bolted to a heat sink and a gate driver, stuff them in a box under the dash and know that I never had to worry about it again.
thanks 'cause i wondered how a "resistor" would be used in a PWM application.
The Neutral Drop reference at the intro was well done!!
Like others mentioned already, I was surprised you did not check the blower anyway after you saw the resistor was fried. If it was shorted, you could have taken out the new resistor rather quickly. Since it often takes me a day or three to get parts, I try to check things like that to make sure I can get it working, or just get a new blower because it is cheap enough to replace something that breaks according to a designed schedule while I got the tools in there.
I hear you on those cabin filter locations. It always amazes me that the car manufacturers make serviceability such a low priority. They harp on doing the filter changes, then make it so you have to disassemble half the car to do a scheduled maintenance. In my Pilot, I knew I was the first owner to change the cabin filter because you have to cut out a piece of the dash subframe to open the access cover. Yes, Honda designed it so you have to hack out a piece of the frame to change a freakin filter! 🤨
That guy who invented the 5.5mm messed up because he forgot to patent it. There was real money to be made there!!! I won’t make that same mistake with my 10.2mm eight-sided design…
I had a feeling it was the blower motor all along. That is simple repair and easy to get to both those parts. Now I had to change my blower motor on my Mercedes Benz 1987 300TD. That is a tough one to get too. It is just in front of the firewall and you have to remove a lot of stuff to get to it, like that wiper motor. Now the Resistor is under the blower motor and that is a real experience to get. Now I see why a shop would charge like $900 to change out a blower motor..
i was worried when you dident check the blower motor before you sold the job ..been there done that and still do from time to time glad to see even you make mistakes i have been doing this for well over 30 years and not to blow smoke up your ass but you seem to be a great honest technician and business owner ..count your blessings (and i am sure you do ) with that awesome family you have
I would have seen power at the blower motor, figured it was the only problem, replaced it and then found out afterwards that the resistor was bad, too. I'm used to the GM thing where if it was the resistor only, the fan is stuck on high. I've never seen both bad, but I get how and why one can cause the other to fail. Great video - thanks for posting this!
Eric you forgot E, when I still was a
tech at a Buick Pontiac dealer I had
a Grand Prix with the same problem,
the blower resistor was burnt out and upon further digging I found the
AC drain was clogged and the condensation leaked into the passenger floor board burning out
the resistor!! Spiders love crawling into
the little rubber boot covering the
drain tube!!! Nice work Eric!!
As usual Eric you're the king of the electrics and you checked it before you replace the parts that's a best thing about you and you did it good and look at that disgusting looking cabin filter tell that customer change that filter more often .
Kudos for trying the resistor first, then blower motor.
It amazes me that people don’t even have enough respect to clean crap like crona equipment when dropping their car off for service.
Just think what their house looks like from the inside!
Agree, I usually throw all my garbage away at the gas station. I'll usually even go to the carwash and hit it with a degreaser if necessary
@@markkrispin6944 My dad and Grandpa ran a small HVAC company when I was a kid. The stories they told...

@@mattpobursky850 Yep, I occasionally watch Steven Lamoniere (sp?) here on the Tube and he serves customers in his HVAC/plumbing business that are like that, live in not quite abject squalor, but some come close in the south Boston to the SE corner of the state and many are as he calls it, not Taj Mahals or mutters it's a "shit show" as far as their residence is concerned. Mind you, many elderly and many are at best working class types.
Hey Eric O, been watching your channel now for a year...thanks for sharing your videos! I'm an aircraft mechanic by trade and a DIY auto mechanic on the weekends. You've taught me some tricks that have made the job easier...even on the jets that I work on. I also live in the rust belt, Minnesota, and my next investment is going to be a torch.
Looking forward to getting my SMA hoodie. I will wear it with pride in my hangar.
I agree 👍 💯
That's such a cute little ratchet and yes the 2000 Silverado has side-by-side cabin filter, mine does. Great video Eric O..
lol the Nissan Altima cabin filters always crack me up, Eric’s not playing, you literally gotta fold the thing up like an accordion and stick it in the hole and hope it flips itself open all the way lol, absolutely ridiculous
A cabin air filter is a must to keep clean. I have changed my share of resistors and blowers.
I just delete them in my cars. Complete waste of time.
you could have got the power probe out and showed the people , apply power and ground no whirly gig . your a great instructor ! learn from you all the time thanks
"Do it like you were working for your mother." Love it Eric.
Was watching a u tube video changing the the cabin filter on '01 Silverado. Thought to my self maybe that's why the system isn't working well. Didn't even know it had one. Took it all apart, sure enough it was plugged solid. Changed it out works good now I've had the truck 15 years and I think this was the first time it was ever changed.
In the 1970s I had Snap-On screwdrivers with a hex on the shank for putting real torque on it. The hex size was - you guessed it! - 5.5mm. I had a 5.5MM Snap-on combo wrench to work with them.
BTW, the resistor pack has more than the resistor(s) in it. They include a thermal fuse - it opens when it gets to a specific temperature and doesn't care much about current. Who wants a fire in their ventilation ducts?
I have an 08’ F350 I pulled the Fonzerelli on 4 years ago, I have a 150.00 blower motor in the basement waiting but it’s been working ever since ! Lol never underestimate the Fonz !
Love the content, seems like your doing more videos and I love that. I feel I am always learning something new from you.
I enjoy watching you man, you take pride in your work which is ver respectable with how many bad and shady machanics there is and on top of that you crack me up with the dad jokes and mechanic jokes all around good people and run a great shop. Keep up the great work and positive attitude. I just did the blower motor in my 97 silverAdo.
I had to change the blower in my wife's SUV, it was squealing louder then a cat that has its tail caught in the door. Thanks for the video and being a good Teacher.
My favorite blower motor resistor story: my '99 Camry. Blower motor had a bad bearing, so it made a horrendous racket on high, but was fairly quiet on the other three speeds, so I didn't really care. Then, the blower motor resistor fails about three years later, leaving me with ONLY high. Down to the Auto Parts Box Store, plug that puppy in so I could have heat without deafness but didn't bother actually installing it - I left it hanging under the dash for the ten minute drive home.
The new blower motor resistor lasted almost two minutes before it failed, leaving me with no motor operation at all. It was a cold drive home for a stupid mistake, and when I got home I heated up the soldering iron and re-flowed the solder on the thermal cutoff (it was merely two metal tabs soldered together) and did the RIGHT THING - I installed it as it should have been, where airflow keeps the thermal cutoff intact.
Two years later, it still works, and yes I did end up replacing the blower motor when I had to start doing the tappy-tap to get it spinning.
Made me smile. Normally if the blower does not work it's the blower motor. :-) Enjoyed watching.
Safety rules require the blower motor to work on high speed even when the resistor fails in order to defrost your windscreen. Oh, try changing the cabin filter on a Volvo S40. You have to remove the electronic accelerator pedal. So much fun.
I was wondering why you didn't give the motor a ground in the beginning just to test it. Normally, I see you do that in other videos when testing things. I've not had good luck with non-OEM blower motors. They are normally louder and sometimes do not blow as fast as the original.
The ebay ones are the best
Even if the blower was working I'd still put a current clamp on it. If the circuit is on say a 30A fuse and it's pulling ~20A+, pretty safe call to swap it out.
@@SerenoOunce we serviced a fleet of Chevy Express vans at my last job. We kept a least on water pump, radiator and blower motor, resistor in stock. Talking to one of the managers for the fleet account he explained to me how they stopped using a different shop due to reoccurring blower resistor problems. Turns out they never bothered to check the amp draw on stock ORIGINAL blowers..its not uncommon to see close to 25amps and a nice 30 amp spike on a 40amp ckt. Obviously a new resistor won't last long in that environment. Its important when diagnosing vehicles to understand the root of the failure and having good fundamental knowledge is important. Unfortunately with the quality of replacement parts today it can be easy to want to chalk it up to crappy parts too..That's what separates the parts changers from the diag techs.
5.5mm is actually a very common head size in my experience. It's the default size for M3 nuts. When your screw is only 3mm, 0.5mm is much more significant then when you have a fat M10 bolt.
Randomly used on Generous Motors Resistors too
You r an absolute champion cobba,enjoy very much what you do
I think you're exactly right about the 5.5mm scenario! If there's a way to complicate a repair (crab assing it into a spot a contortionist can't reach) or adding more specialized tools, the automobile (not exclusive to automobiles) makers will find it. I think they start out the design process focused on deterring easy maintenance! After working on my own rigs for the past 45 years, that is my conclusion. Another great vid, Eric! 👍
Car design 101, take an engine. Then build the car around the engine. Don't worry about having to service the engine or anything else. Just jam everything around the engine.
Shit, we built the car and forgot the battery, there's no room left for it?!?!?! Hmmmm, stuff it in the fender-well.... aka Chrysler BS. lol
Remember when you could open the hood ant there was an engine there, now you've got to get past the pointless engine covers. Why?
@@watsisbuttndo829 Mice love chewing electrical wire (plastic coating has a soy content), so why not build them a roof for their "house"?
I like when you work on Nissans. A rare thing in your part of the woods!
On my wife's Nissan Sentra the filter is one of those wad it up-stuff it in- hope it opens type of filter that spews the filter contents all over as it comes out. Who designs that crap? On my hyundai you open the door slide out the old one slide in the new one-done. No mess no fuss and 15 seconds worth of work. Great video and its nice to see the little U scope in action.
You said doody! Lol! Well you did! (Sometimes I am 12 year old again!) Then I heard your "Wera tool" joke. Lol. Great use of the mini scope. I needed a welders helmet on for how bright that bulb got! Good call on not wrecking the new resister with that bad blower motor! Who knew? Fixed moms car lots! Mom and the car both gone now! Good video Mr O.
really enjoy your videos.watching from england.R.Parker USAF MSGT Retired. Thanks
I didn’t get my “come on baby” but I did get “oh yes baby instead”great vid Eric, greetings from Ireland
Another great video! We are really getting spoiled with all these videos! Don’t stop now! 👍👍👍
Hi Mr. O.
How about hot gluing a pine tree freshener to the cabin filter... Treat them to months of Christmas fragrance.
P.S. you're the smartest old soul I've found. Keep em coming.
I had an older Ford Taurus with a runaway blower, full blast. Glad I had a service manual with schematics because I had no idea there was a resistor that controlled speed. Quick, easy, cheap fix (way before YT). I’m sure your video will help a lot of people.
another late night auto mystery you should write a book Has my attention to the end 😎
Nice work! Man that two piece air filter, help me understand. Reiterates my opinions about working on Nissan.
Loved the flash light as a push bar / hammer, application.
Thank you for your attention to camera angles, it’s definitely not easy doing this without a video recorder, but with it, just makes it that more difficult. Thank you sir.
Wow a blower motor thats got all screws accessible, thats actually amazing within itself.
Had a customer that would turn on the AC and had no air coming out of the vents no matter what blower speed but could hear the blower going. I pulled the cabin filter. It was completely filled with dirt, leaves and other debris. Replaced the cabin filter. AC worked fine. Had some fun with the customer as I told her it was the climate controller and was going to cost $550. She freaked out. Then told her "just joking" and told her it was a extremely dirty cabin filter which I showed her and charged her $25. She was so happy to hear it was just a dirty cabin filter and not a $550 part. Especially since we need our AC during the Texas summers. She has been a great customer since.
I owned a 2015 Nissan Murano. "Disaster" is the perfect word to describe the cabin air filter location. I changed it once. After that I happily paid a mechanic/contortionist to save my back.
I love it when bit of a detective investigation lol .
A video a day ! santa bills bit spendy this year ! lol .
Have fun . content always good in humour and professional tips .
Great video Eric. That's the first xterra I've ever seen with a stick shift.
Like always great repair, I had replace the resistor on a trailblazer after I check motor was turning on the fan. Awesome content on the video. Take care thanks 😊
I would like to thank you very much for putting on these videos very entertaining and the chit chat between you and mrs o
Good morning everybody !
"Room for probage"...lmao...awesome, Eric!
You getting us spoiled with all the uploads 💪💪
Nice job Eric I just found location of the cabin filter in my Ford F-150 just thought of it by accident
Enjoying your Freudian references about mothers....deep...and hilarious...great video...keep on smashin them out ....love your work...all the way from Brisbane
Eric- I have been using my Milwaukee driver 1/4 shaft 12v (2406-20) for all screwdriver crap. I hardly ever use the nutdrivers or phillipsbit without it. It is not too powerful to tear stuff up put zips most stuff out fast. 1/4 adapter for sockets. tI's small, lightweight and can get into places an impact can't. LOVE IT
At FCA (Stellantis) those are called Blower Power Modules. That one looks like it has linear output with such large heatsink. There are also PWM output modules that have much smaller heatsinks. Good job Eric! Rotor Lock...
By looking at the scope, I think that unit is PWM. The old days of low, medium and high could be heading out the door. Cheers!
Givin it the Fonz is always worth a shot!
Yes, Eric, if you can jiggle it, then I should be able to jiggle it too !!!!! I always put 12 volts to the blower motor first to see if it turns / works. Then I check the resistor.....either the motor is bad, or the resistor is bad - or they are BOTH bad !!!!! Then take whatever corrective action is necessary !!! That's how we do it in the Florida "" Salt Belt "" !!! The blower motor runs whenever the engine is started here, need that cooling air !!!!!!!! You did the both checks, just in a round about "" Rust Belt "" way !!!!! Same objective, just different paths to get there !!! Never seen a 2 piece cabin filter. I have only run across 1 piece replacements !!!! My 06 Ram 1500 Laramie Mega Cab 4 door 5.7 Hemi gave me a P0441 code, replaced the purge valve under the battery area. Reset the light / code deleted, and it was good for a week, then same code came back again. Any other sure fire fixes you know of ??? Going to test the charcoal canister, and parts associated with that, as well as possible hose leaks and gas cap. Can you shed any light what it might definitely be ???? You get it right and I'll send you a bag of Florida sunshine enriched oranges !!!!!!!!!!! Thanks !!! Merry Christmas to you and your family !!!
Well done Watson.
Must be a common issue with the KneeSans... ;) My son's 01 Xterra has the old school resistor and it lost the middle speeds. Only had settings 1 & 4, no 2 & 3 if I recall. Looked liked the middle speed circuits on the resistor corroded open to me. Also had the two piece cabin filters and was full o leaves and "dietz nuts"... I gotta gin up one of those fancy headlight bulb diag devices! lol Keep em coming! Thx
Blower motor went out on my 2005 Golf. It would still run but slowly would grind to a halt after a few minutes. VW wanted over $700 for new blower. I figured out how to get some oil to the rear bearing by removing the rubber retainers holding the motor to the blower assembly . Lubed both bearings and blew out the dust with compressed air, and the old one now works just fine.
I've had my Xterrible for a decade and didn't realize that it has 2 filters, just thought they came from Amazon in twin packs because they are so small and have to be changed frequently. It's going to be a joy to go change the 2nd filter at below zero F temps. Wish I lived in that part of the world, Eric O or PHAD might be able to solve an intermittent driveability issue I have with no codes and no obvious data glitches. Can't scope what you can't see. learn something new every day.
Almost had me snorting coffee. The cup was sitting on the table at the time LOL
I've had luck with lubing the bearings/ on a blower motor and brought them back to life, But that was on older vehicles ..
Again, thorough as always!
Did this very thing on my 04 Xterra years ago. Everything was easy to get to.
Good path to a complete repair Eric. 👍
Eric, last winter my heat quit working. This was on my 2005 F-150. It had over 300 thousand miles on it. Da… I pulled out the blower motor, it was dirty, I hooked it up to a 7 AHR battery and it turned on. But it didn’t spin super easy by hand, again way too many miles on it. This truck has the automatic temperature control. So I bought a new resister, very expensive, put it all back together and it still didn’t work. I then took the blower motor back out and after testing I realized that motor had dead spots, Ah ha! So new motor new resister and it still didn’t work! Running out of ideas I plugged in the old resister and the system worked super! NAPA resister was no good and motor no good.
Moral is motor’s only last so long. Plus no returns on electoral parts.
had to change the cabin filter in my 2011 altima over yonder in medina area, my fat fingers could barely manage to get it in all snug like, thanks for the content
Another fine job by a good mechanic that motor does sound like a turbo
Eric is one of those guys that you could bring ANYTHING to, and even if he's never seen one before, it wont take him long to figure it out. He HAS the "mechanical instinct" that was nurtured by DAD. MUCH RESPECT SIR!
Most men have a mechanical instinct.
Some more then others.
Eric O, the 5.5mm screw is a standard size on copy machines. And let me tell you uncle Chow must own screw factory. 1 medium size machine had 16 screws in back panel. 6 screws would work perfectly. Needless to say walked out with a lot of pocket screws.
That blower moter sounds cool
Thanks for the info.Have an idea now where the resister might be in my Nissan Frontier.
Glad your parts guy got it right. I did all the tests with the resistor in, told him it was for a manual set up, nope. Chased my tail back to that part. If I remember the diagram right, these actual bypass the resistor on low and not the usual high. Weird set up.
Great video as always. Clear demo of scoping the small wire. You could’ve jumpered the connector at the resistor/controller to test the blower motor operation with an amp clamp to measure current when you first confirmed the failed controller to avoid calling customer back. Hindsight = 20/20 LOL.
Another solid entertaining repair!!!
Good stuff!! My retinas are doing fine thanks for asking.
Just wanted to let you know you said "duty " a number of times . And number 2 a couple of times. Do not worry and don't get all self-conscious. It was all in good old fun. A good sense of humor is important in this kind of work.
