Mercedes loss of cooling fan operation

Mercedes Cooling fan

[@mervyn567]

Great video Keith . Appreciate your time in making such an informative clip. We out in South Africa are starved for good wiring diagrams.Can you refer me to some sites that have wiring diagrams for European cars like the one that you used in this video.

[@NewLevelAuto]

Mervyn Naidu I am doing a little preliminary research and it seems that auto data offers the best wiring diagrams for your area. but I will continue to search

[@kitecattestecke2303]

emanualonline dot com if you want "original" manuals and/or semi legal from the car maker
or if you are diy just one car person:

[@dylankinch2735]

i cant believe there were no voltage drop issues before this wire completely rotted away. you would think there had to have been. great video keith. love your procedures and how u track down problems man. u make it look easy and i certainly know it isnt.

[@NewLevelAuto]

Dylan Kinch I keep insisting that there had to be some type of an issue but the owner swears there was nothing . Either way fixed and I move along to the next one

[@anthonybeaudry6066]

Hey Keith, with all the "NEW" parts on the front of that engine it screams ACCIDENT to me.
would not surprise me one bit if that wire was pinched in the process and never fixed or it
was overlooked. Just saying

[@kevingallich5557]

Even with a voltage drop which I believe would just mean a slower fan speed the ECM would just compensate by running it at a higher percentage? So unless you were sitting on a highway in traffic in high heat you may not have noticed anything.

[@NewLevelAuto]

Kevin Gallich I like the thought process , however even a higher percentage can not overcome the laws of electricity . Only x amount of current can get through y resistance with z amount of voltage supplied 😉

[@kevingallich5557]

Pesty laws! Thanks for the knowledge. Stay safe!

[@gregoryellis7391]

Great video!! You have such a wealth of insight and knowledge, so glad Erick and Ivan talked you into doing videos. Your videos will definitely help a lot of people learning diagnostics.

[@NewLevelAuto]

Gregory Ellis glad you are enjoying them. Always feel a little funny making them , but I am glad to help anyone I can

[@denvermock1898]

@@NewLevelAuto where is your shop?I need some help..

[@suedoenim216]

Car newbie here trying to get my older Mercedes going again. I really appreciate how you just walked me through this process step by step with the diagram and testing the lines. I don't have any type of computer and I'm trying to fix this on my own, but I can't believe how easy you made something so complicated seem. Thanks

[@NewLevelAuto]

Thanks ! Best of luck on the restoration

[@DavidS11]

Another nice and quick video, I feel like I am finally internalizing the proper and optimal methods for diagnosing.
Really appreciate the effort you put to get this videos online, really helps and encourage a lot of young techs like me to learn and become better

[@wysetech2000]

Very well done, Keith. Simple, straight forward and accurate diagnostics. I think twice about opening the hood on one of those turds.

[@AhileyGusani]

Not gonna lie. One of the best mechanics out there. A lot of people will not bother what you did and probably Will tell the owner to replace the fan 100 times. Much respect, thanks!

[@billyr9840]

Nice ! Keith, I like your style of diagnostics and vids. No drama, straight forward and plain common sense !

[@NewLevelAuto]

Billy R I kinda have to stick to that mindset with the number of cars needed per day. Thanks as always

[@billyr9840]

You know Keith, it's all about the money ! Keep pumping them out ! Take Care !

[@StopDropandLOL]

Great video Keith. You make diagnosing potentially puzzling issues simple by breaking it down into logical steps. Keep up the good work!

[@juanhinojosa6272]

I really do appreciate the videos. I've always been intimidated on working on electrical issues, but now notice there is a procedure everyone follows to trace down faulty wires. It really helps a lot. Thanks for the vids.

[@NewLevelAuto]

Juan Hinojosa my motto is "they are just machines" . They don't have feelings and they don't try to intimidate. In the end all it comes down to is basics .

[@todayintheshopbanksy5904]

Thanks for posting Keith, appreciate you taking the trouble to bring us along.

[@fredjohs]

Thanks Keith for taking the time posting this! Less than 15 minutes (including filming) and problem solved - you're the man!!

[@spdparts8924]

Initially when I saw Mercedes cooling fan, I guessed fan control module, I've seen couple of them went south, and when I opened one of them, I saw exploded transistors, probably fan motor gets shorted inside and blows up transistors inside. Good diag video!

[@attilakohbor3360]

German cars have never been good on electronics , failing fast .

[@rollingrockfan2482]

Another great video from Keith, really like when show it all and there not edited to death I think viewers appreciate your time and effort A+

[@leedress2187]

thank you for making videos. it's great to have thinkers and not parts swappers showing what they do.

[@TheDisgruntledMechanic]

Just ran into problems with green crusties on a wiring harness at work. it was an easy fix once I found it! nice work Keith!

[@baxrok2.]

Wow, that's some quality green crustiness. So very nice of it to show itself off so clearly and out in the open! Nice work sir. Thanks for taking the time to share this!

[@SouthMainAuto]

Heck yeah that was a nice big puss sac!

[@xerxes456]

Fantastic explanation with the wiring diagram and circuit. I think it is wonderful to help us who's watching thank you for the videos and your time I try to compensate for your help trough paetron and hope a lot of people also do the same.
For me, it is fantastic to learn the German cars been driving those all the time

[@NewLevelAuto]

g johan it is really appreciated that you would contribute not only monetarily but also with your kind comments . Thank you again for your support

[@aviewisaview]

I need to get my ac looked at. I been putting in the DIY freon from Walmart but it never gets cold. Fan works and it cycles but stays hot.
You are very detailed in figuring out what is going on. Good job.
Thumbs up and shared.

[@NewLevelAuto]

A VIEW IS A VIEW I can find you a decent shop in Atlanta who will take care of you . Better yet come on up to NYC and we will fix it together.

[@aviewisaview]

I will be up in NYC /Jersey area sometime this year. That would be great.
I brought this 1998 Jeep Cherokee for 1200 bucks and have driven it for 4 years. I fix a little on it a time on it. #TeamNoCarNote.
Have a good day.

[@mikechiodetti6737]

I forgot about all the corrosion seen on or in vehicles from the Northeast and upper Midwest states. I've lived in Southern California away from the coast, since 1976, but I do remember what the salt did to Massachusetts vehicles! Good diagnostic work!

[@kevingallich5557]

Great video. Surprised at clarity by using your phone. Short sweet and to the point and fixed. Nice!

[@billsmith2212]

I am not an expert , BUT - if the car was running hot , you put in a thermostat , water pump and fan ? But you never check that the fan works - FIRST ? What if you ran jumper wires to it to see that it operates - why replace it ? Diagnosis VIA parts cannon ! Replace EVERYTHING - it's gotta work . We don't need no stinkin power ! How do they get away with it ?

[@pinpointautomotiverepair1592]

The green crusties man.... Every time! Great vid Keith, I don't think you stumbled around too much at all!

[@Matbug1812]

I can understand people calling on you for data com issues, but it's Unbelievable that a repair shop can't diagnose an open circuit on a power feed! ...Love your videos!

[@SmittySmithsonite]

I'm learning to hate Euro wiring diagrams. Why can't they just label stuff on the diagram, instead of the number/letter game? The last Volvo diagram I attempted to decipher had me ready to pull my hair out!
Great vid Keith, and THANKS for posting it!

[@chungaleta1234]

Great vid Keith. Bloody Benzes and Beamers look so intimidating, like working on an alien spaceship. Loved the PC with the pen marker, perfect for tutorials!!!

[@maksn5751]

Awesome video. Glad I found you through SMA.

[@satamanschmidt3428]

All of these comments are talking about the same thing but they don't realize it. What Eric, Ivan, and Keith have in common, which VERY FEW auto mechanics have is PASSION for their profession. When you bitch about parts changers and hacks and people that don't give a shit vs. these guys that's the difference. Are these guys motivated by money, of course they are, but they truly like what they do for a living. I was the some way with Semiconductor R&D and Manufacturing. I loved that shit. Did they pay me a lot of money to do what I loved to do anyway, YES. But making electrons do what I needed them to do is what I lived for. When you're just going to a job that's paying your bills you never put the effort into it that you do when you're doing something you love. The primary job of high school should be exposing students to as many different professions as possible so that a kid can pick the one he's going to do for the rest of his life and enjoy it. Instead they throw him out the door after graduation and hope that he finds something. Another failure of the American educational system.

[@NewLevelAuto]

SATAMAN Schmidt very well put as always. And I agree , teach them about the things they can use to have a successful career. I think you should do a live video about just this topic !

[@chrisbowerbank5044]

Nice video Keith. May seem like simple problem solving to you but invaluable to us DIY'ers. I learn something with every video from you and Dr. O.

Thank you so much sir I put a brand new radiator and a brand new fan and module and my son 08CLS 63 AMG after it was real cold I was sitting in the parking lot at work and the radiator just blew coolant all over the place I told it home and have not been able to figure it out since the fan will just not work but this video is very helpful and tomorrow morning I will go out again and go under there and find the cable first I’ll find that power box and test it with my own meter that has power and I’m hoping that maybe something was ran over to and it’s a broken wireAnd it’s OK that I spent money on a plan and other things because I am learning thank you so much sir

your doing great keith considering the fast track enviroment you work in and limited time you have , at the point you spotted the green crusties i was so expecting a "well theres ya problem lady" , i guess thats what you get when youve watched alot of Erics vids , maybe you could drop it in on a future vid it will defo make a lot of people chuckle , great vid keep it up .

[@jacobusa4727]

Nice diagnostic lessons to be haved, last 42 yes dealers. and franchise's have been parts changers they would starve or close down but there is a plus gives real techs and honest ones like you guys and a like on YT work and demo your skills that are lacking in this industry which has been deemed rip off's and highway robbers, once a true tech along with mechanical skills costumers will be keepers rather than hopping garage to garage,,
so those who call themselves Techs but really mechanics need to go back to school and learn how too proper diagnose these problems,
thanks Keith for a wonderful lesson on how to be a true Tech and not just a mechanic,
mechanics need to earn there badges by becoming a real Technician not by just a title that some mechanic call themselves,
but authorized by those schools that provide such opportunities this is the future
and cars are changing quicker than we can learn about diagnosing future problems
we have no clue about as just being a mechanic ,and is my point,
again good show Keith

[@NewLevelAuto]

jacob USA there are people I've seen out there that think that testing a solenoid is as simple as hearing it click, so I know the type you are referring to. What I can't understand is that with the wealth of ways to teach oneself nowadays that so many choose to use nonsensical methods in order to prove that they know something. I don't even teach a student that says the words "I know " more than once. The best way to learn is to admit that you don't know it all. On a bit of a ramble here ,but point is , take the good testing methods you see and apply them . There are some great guys doing great video like Eric , Ivan , Paul , Triangle, and so many others that each person should have a pen and pad handy at least to write down the titles of their videos and keep it near their toolboxes. I am glad you enjoyed my video and hope you'll like the others to come

[@jacobusa4727]

New Level Auto
in school one learns the basic and those want to pursue further education the automotive field take advantage what they can learn for free on YT yes eric paul Ivan keith Joe good source of fas diag, and in real time ,in school one gets basics once out in the field now there problems that where never duplicated in class because so many things can cause similar problems which may lead to the real problem source,
automotive mech that have the basic now they need to get into the real world and finding a good work place that will apply training and begin an apprentiship, I started when 13 in 1972 today its has change 360 degrees we need to give them the chance to excell otherwise they loose interests and just have boxes collecting dust. BuT you guys make more fun even though frustrations at times ,
every car is a learning experience listen closely and ask questions when you don't now and this will show you're willing learn and then you will get help truly needed

[@stuzman52]

Great video Keith and the explanation was clear enough that anyone should be able to follow along of what you are doing. I replied to your comment here because I see the same thing with new people at work that I train as new engineers right out of college. It still amazes me how management believes that someone with a degree is the almighty, supreme high intelligent being who knows all. And some of these guys don't even have any common sense and as you've mentioned, they pretty much know everything anyway. And what's more amazing is that there are some sharp guys on UA-cam and the information is there, but people still like to just change parts and couldn't care less of how stuff works. I know it takes a lot of time doing the videos, but it will pay off in the end as I'm sure there's still a lot of folks out there who would like to learn the correct procedure of diagnosing and how systems work. Have a good weekend Keith and don't work too hard.

New level u couldn't have explained any direct than what you explained! Great tutorial. I on the other hand am a do first then explain. Not gifted in that area i suppose. However once i put hands on any of the jobs take from customers. They are all ways satified. Oh one other thing ..... A quick fix sometimes is as good or if not better than the right way. Find myself in that situation often. however i do warn the client about the temp fix and so on.. Keep up the good work
Mech. Pro. Also when u located the problem there was no one to cheer u on. self satifaction! But i shared the joy with u! i know the feeling its as if God came down and touched u on the shoulder.And the moment that fan kicked over! Exciting! My GF doesn't see as exiciting. Up until i told her to take her benz the work shop! LOl!!! Keep at it my friend the Mech Pro Gods are their with you!

[@jfjerez]

Excelent video…
I had similar issue twice in my C230. In my case was failure of the fun. Maybe because I live on a hot weather are in which summer 120 degrees is normal I assuming inside the Engine it should way higher makes the fan to fail. I seen at least one video in the net in which one person open the fan ( had to cut enclosure fix it and glue it back) and found cold solder on some capacitors that reflow of the solder fixed. I ask to keep the old fan so when I find time I will open it and double check if that is the case.
But 100% correct if the fan don’t work the AC fail to work also.
Thank you

[@daveyio87]

Great Video! Its really sad how many so called technicians are out there who can't diagnose something as easy as no power at the fan module! Always gotta check your power and grounds before replacing a component even if its a known failure component because 1 out of 100 times you may find a broken wire!

[@NewLevelAuto]

daveyio87 keep in mind that it's also HOW you check the power. If you used a volt meter and 2 strands of wire were still good what would you read ?

[@lifekludger]

in that case wouldn't there be some voltage only reduced due to higher resistance? Great vid. Thanks for your time and also the comments.

[@daveyio87]

Good Point! I forgot about that, in school they actually tricked everyone. put a resistor on the power wire and it light with a test lamp. most everyone said it lit the test light. a few said hey that test lamp is kind of dim. they were teaching us the value of using voltage drop to test for some problems. But most of the time i use a high impedance test lamp, and if i want to be sure of a good power and ground ill use a head lamp bulb.

Toyota and Honda ain't got nothin' on the M112 and M113 engines! Great engines! Sweet video Keith! I could've sworn it's the fan control unit(those go bad all the time) until I saw " open circuit ". Front end collision and things don't get fixed and put back in place=problems. Maybe I'm wrong,but it looked like that wire got partially cut from the impact and it might have worked until the green crusties set in...?
That's a good car(except that it's a wagon. Lol),I really don't get why some hate on these. I had an E55 AMG,that thing was a monster! Loved it!
Thanks for the video! 👍👍👍

[@andrewk778]

Does anyone check for powers and grounds before replacing parts? Thanks for another interesting video.

[@josephwash109]

Not part swappers. When they "diagnose" a vehicle, they pull the code and whatever component is mentioned gets replaced. In this case, it was the cooling fan. The fact that the code explicitly mentioned an open circuit was above their heads.

[@NewLevelAuto]

Andrew K lots of parts cannons loaded up at some shops. At least when it came to this shop he admitted not having proper wiring diagrams.

[@robe5000]

New Level Auto no diagram, there was a big red wire going to the fan! I feel bad for this guys customers.

[@elit3darkness]

Great start to the video, I almost skipped it then realized I own a benz....

[@MaicSalazarDiagnostics]

Great video my friend! Good diagnosis procedure! I want an Autologic!!

[@NewLevelAuto]

Maic Salazar not anymore you don't. The new version is not nearly as good as the old blue box for programming and coding. As for datastream, bidirectional , and refresh rate the New unit wins . But honestly can do almost all of the same minus coding and programming faster using my launch. Plus the launch allows me to choose just the pids I want shown from a huge list

[@MaicSalazarDiagnostics]

Taking the vids will get easier over time, and it's surely appreciated! Looks like you're about to oust someone in my YT top three. So it would be you, Eric and Ivan. Keep it up!

CleanSC you know the temptation to ask is killing me right ? 😉

[@CleanSC]

Hahaha it's Paul but he's the man so instead of having a Top 3, I'll just make it a Top 4 so I don't have to kick anyone out!

The cable ties and tape didn't look factory, probably the insulation rubbed through and then the green crusties went to work on this one...Still impressive how such a thick cable got completely eaten.
But overall I have to say that Benz looked in amazing condition for being a 2002. But the C-Class usually is pretty reliable (when you count out the early 350 V6s from the mid 2000s...they were garbage because of that balancer shaft gear defect).
Good video, as an engineer it is always very interesting to see how products do in the field and how you can debug a system you have not designed yourself. Although I'm not in the automotive industry, it sometimes makes me rethink my decisions. Because if stuff comes back from the field with a fault, good debugging capabilities can be very valuable.
