- Honda Accord A/C (Air Conditioning) Troubleshooting and Service. Honda Accord A/C doesn't work, only blowing hot air. This Accord AC was blowing hot air inside the vehicle, the air conditioning was not blowing any cold air. I troubleshoot the A/C system on this Accord to find out why the air conditioning wasn't working properly and I also recharge/service the A/C system. The exact vehicle in this video is a 1997 Honda Accord EX Sedan. Enjoy!

I would bet that the leak which is now very small is located in the sharply curved discharge rubber crimped hose towards the right side of the engine compartment. I have this same problem on my 1994 right now, it started out with the leak being so small it was impossible to find it, however now it has gotten big enough you can see the pag oil residue on the side of the black rubber hose right where it crimes in as it migrates up the hose.
This man should teach a course on how to explain something. Wow so descriptive. Thanks man
Your video gave me the confidence to go ahead and recharge the coolant system on my 2002 Honda Accord EX (4-cylinder VTEC engine). Interestingly enough, after completing the recharge, my hi/low gauges showed almost the exact same settings you had when you finished. I had never done this before and I'm quite happy with the outcome. My car's air conditioning is now working well. I'm planning to watch some more of your videos. Other UA-camrs would do well to emulate your style. You do a great job. Thanks! - Richie
I cannot believe the level of detail and knowledge in this video. You're a true pro and an excellent teacher! I don't know anything about cars and I was just searching around for a quick diy fix for my AC but you're explanation of the process and all the different things you consider really helped me understand the entire AC system in my car a lot better! Keep up the great work!
Thank you, I appreciate the comment!
I’m extremely glad I watched this video before attempting to fix my Air Conditioning, 11/10 video
👍
I like the way you did a long vacuum, some guys seem to finish that phase too quick. When the system goes to vacuum, water can't exist as a liquid so it boils off, but as it does so there is dramatic cooling which can cause small amounts of water to freeze in the condenser and receiver/dryer. Then it takes a while for the solid ice to sublimate to gas and get vacuumed away. It is so nice to see a pro do work like this in a small garage setting. You obviously did this for a living and are now at the phase where you can take time to educate people like myself.
Great video on Automotive A/C. I have two cars like this one. I love them and have restored them. However, the A/C just died in one and I was looking for component locations, as I suspected a bad pressure switch. Thank You for all your hard work to make this. Aloha and Mahalo from Hawaii.
I really appreciate the amount and even more so, the quality of the information shared into this video. It certainly took a lot of effort. Thank you so much!
I just bought a 94 Accord with a ac problem this video has help me save money to diagnose the problem thank you sir
I enjoyed the overall component locations. Very well explained as well. 52 degrees is pretty dang good. I just finished a 20 day trip and my A/C was maybe in the 70's.
Good to hear you made it home safe, thanks for the comment Wyatt!

Great video, going thru all the steps of eliminating issues was great. I have been in classes that did not do as good job as you did... thanks alot for postiing.
I appreciate the comment, thank you!
650Kgrams is roughly a third of an Accord's weight.
.650Kg is within range.

Really great video big dog thanks a bunch! I learned a lot in those 25 minutes
I appreciate the comment, thanks!
Holy crap! That is a fancy smacney AC machine! Thanks! When I need the AC in the 2000 Civic done I am coming to you!
lol, deal!
Great video, definitely learned a handful of useful things
This video made me feel better my 01 honda got down to 50 degrees sitting still. 👍
👍
awesome video , thanks for all the info to troubleshooting .
Big dog with big enough details...
Great video.
Thanks
Thanks 👍!
Nice work! Extremely interesting.
Coolv video 👍 Just serviced my 97 Accord yesterday. Replaced both high and low Schrader valves due to leaking freon. Purchased R34a with gauge and AC oil. Got the AC to a cool 42 degrees during 108 degrees desert heat. What a difference it has made commuting to work 😎
👍
Winter in your car.. mine is Death Valley in my car
@@ravishoul1432 Right! I forgot how fun it’s to drive my Accord again opposed to melting on my commute back home 🫠
@@elgatogordo9523 It's my own personal mobile sauna

I have 2004 Expedition blowing warm air while driving I replaced the TXV expansion valve and it is fixed and also the blend door actuator was clicking so I replaced that too.Yutube is a big help in DIY people like me.
Good info as always thanks for sharing brotha.
No problem 👍!
Whew! It's really hot where I am! Well, outside it is, not here in my air-conditioned shack! I'm coming to you if any of my A/C systems break down. I suspect you'll take payment in cold beer. Great video!
Beer!!!!!!!!!!!!!!!!!!!!! ;)
Good Video Dave
Thank you for sharing
Awesome video thank you so much! I’ve always wanted to have an idea of how the ac system worked in cars thanks your video I have a general idea now. Nice ac machine btw I looked it up and wow they are pricey!
Great video 👌
I need to get my wife mini van a/c fixed. It's leaking from somewhere. This video gave me a better understanding of how the system works, that way the shop can't give me any 🐂💩 explanation. that's if they try. Because now a days, people will rip you off if you don't know, or have an understanding of how things work. Thanks Dave for making this video 👍🏻🙂
Glad it helped, thanks for the comment!
Nice job. I like the diagram most.
Very nice explanation of Honda AC system...wish we were neighbors!
Thanks 👍!
@@BigDog50001
My pleasure!
I'd ask what your schedule looks like for today so we could sit around and laugh about all the mistakes I've made diagnosing my AC ....but, I don't think my wallet would appreciate that.
Man that is hot 117! Well explained video on auto AC charging. Outside air temp at condenser compared to inside AC air vent temp equals the Delta T. 50 degree difference is pretty good, maximum legal reflective window tint all around and your good. I am in Florida an did a shade tree AC gauge charge. No recovery machine or vacuum pump and I am at a 45 degree Delta T on a 95 degree air temp with 60% humidity on a 93 Accord.
👍
Awesome explanation 👌
I appreciate the comment, thank you!
This video will help a lot of viewers😁
I hope so lol!
Another great video! Thx!
Thanks for the comment!
Great job with the explanation and you’re right that having an a/c machine can help with diagnostics. Have a good one! 😀👍
Thanks 👍, you too Stuzman!
My 1995 Accord Ex still on the factory charge and still blows ice cold. A testament to Honda quality of Generation V.
Respect.
Then why the are you here? To rub it in to everybody else whose isn't?
@@ButterfatFarms I'm a cruel one aren't I?
muwahahahahahahaha!
I agree with you. My 2002 Honda Accord EX went 18 years before it finally lost most of its refrigerant. However, because I was extremely busy, I didn't get around to recharging it until now. But I have to admit, I also feared taking it to a mechanic who might say, "You need a new compressor, and I recommend you also install a new condenser. That and recharging the system will be $1400." 😨Gulp . . . That's about as much as I think I could get for the car. I was able to forego the recharge for four years because summers are cooler here in Idaho. - Richie
Excellent video!
👍 Thanks!
Howdy, Big Dog50001 Automotive. it is a extremely great video. thank. :)
👍
Great video 💪🏾
Very good explanation with the diagram
Thanks Antonio!
Thank you for this. Best explanation.
You bet , thanks for watching 👍!
This is good service most places would’ve just said give us 2k and we’ll replace the whole system scammers these days
great lesson. real pro. thank you.
Thanks for the comment!
Perfect . Great video .
Thanks 👍!
Hi Dave good video with an excellent explanation of how the system works. Man 85 degrees coming out of the vents would of felt cool. I think will have a frozen coffee today. Anyway hope all is good and family is well. Stay cool Artie ☺️
I was definitely not drinking a hot coffee while I was working on it lol, thanks Artie!
Phenomenal video, I have the exact same car and my car leaks ever so slightly from the shrader valve on the low side. When interpreting your pressures I noticed in the video you have the engine at around 2k rpms. Should the engine be revved and held when checking the pressures or is it done at idle? Thank you!
excellent video
Thanks!
Thorough mechanic
I have a 2007 Honda Accord that is only blowing hot. This video really educated me on my cars A/C system and I appreciate it and you BUT I don’t have access to those fancy machines you use while eating popcorn and drinking sodas so I was just hoping to get an honest answer on what I should expect to spend to get mine charged up ? Mechanics like to take me for a ride and I don’t figure it out until after the fact.
Great video
Thanks!
I like your funny words magic man
I like the fact that you explained why if the pressures didn't equalize that it could have a restriction. Had my A/C checked, Mech said,1st pressure Check 10LP -75HP. After evac and recharge pressure readings were 105 LOW side-110 HiGH side.ambient temp was in the 90's I live in Colorado. Mech said would only take 9 0z.. But I know the air gap on clutch prevents engagement unless clutch is tapped.Maybe he didn't realize clutch wasn't engaged? And concluded compressor was bad? There is enough refrigerant in system to allow compressor to engage. but only blows hot air. Diverter valve works, A/C condensor fan works.Compressor is not seized but maybe just worn out? Suggestions any one?
Excellent!
Thanks!
Cool video, wonder how many shops actually do any of this vs just recharging. I think the owner is spot on though. Getting down to 54' seems pretty good, not sure why it would be worth spending real money to get it better.
I appreciate the comment, thanks!
Nice explanation and repair. I like you AC machine Robinair make some nice equipment for sure.
Thanks Jim! I agree, they do make some nice equipment.
Yeah I love all the equipment they make! So easy to use, dumbass can use it.
@@BigDog50001 Hey, Watched a couple of your videos. I have an issue when I operate the climate control manually (Auto turned off).
With the AC on, the only time I get cold air is when I set the climate control temperature to low, any other temperature I set the controls to i get hot air.
When I need heat in the winter and I turn the AC off, the only time I get heat is when I set the climate control temperature to hi, any other temperature I set the controls to i get cold air.
Any advice?
Awesome 👏🏽
Thanks 👍!
Sweet video. Me gusta.
Thanks!
My accord 2013 V6 Coupe , we tried recovering the refrigerant, it came at 530 grams, we put that back , everything is working but the low pressure and high pressure were not in the recommended zone , in other words low pressure, even though I recharged the system to full, its still blowing hot air , do you reckon it can be a bad expansion valve ?
Great job with the video. Good amount of explanation to cover old and new vehicles. What would you charge for the service you performed?
This would probably be in the $200 range but it depends on the area and how much the shop charges per hour for labor/diagnostics. Thanks for the comment!
My honda has a hissing noise when not turning the steering wheel. The moment I turn it a bit, the hissing stops. The noise starts about 5 min after turning on my car. Could it be my power steering? or, from what I see, there is a leak somewhere in my AC. Could it be because I didn't use my AC for some time? It's what i'm on right now. Thank you for your video! It helped understand more on how it is built!
I had been following him since 2015/16 back when I have Ford trucks
👍
Will a bad expansion valve keep the compressor from kicking on ?
Great video Big Dog50001 Automotive !
Working on my 2002 Honda Accord..starts off cold then blows warm and won't blow cold again until it stops and sits off for about 20 mins. Any ideas? TYVM!!
Probably need to have the ac charged up on my 4runner its never been charged the 15 years i have owned it and its 20 years old still gets cold just not as cold as I like
Awesome video. I have this exact car with the same symptoms. My compressor runs as well and low pressure side never gets cool at all. I learned a lot. However my refrigerant is where it should be. Not low at all. My fans kick on when the a.c. is on also. So I'm thinking I have a bad expansion valve.
👍
Did you ever get it fixed? Definitely sounds like a restriction, most likely in the txv.
I didn't know it's so involved. I recharged my old 02 Accord several months ago and it blew cold air for a while but now no more cold air. I am wondering if it's really a compressor problem now?
thanks
👍
I am troubleshooting an ‘03 Accord. The two cooling fans do NOT come on when I turn on the AC. Is this an instant problem, or not necessarily a problem?
hey big dog got a question. 2006 Civic EX, when the AC is on, the engine stumbles at idle. Does it every 10-15 seconds. Any idea as to what I should check? I just had some AC work done at the dealer, they wacked me for $550 and I don't want to take it back. Thanks in advance.
so i have an 06 honda accord 5spd manual....i recently replaced my compressor, both cooling fans, new condenser and dryer....but after the install, when i press the AC button in the car, nothing happens. I pulled the relay and jumped it and then and only then will the compressor clutch kick on but as you know it needs the relay to disengage and re-engage the compressor so it doent burn itself out. I cant imagine a broken wire since the radio/climate controls havent been removed and tampered with and it worked before the install albeit with a leak in the condenser. What do you think could be my issue?.
How do you test the 2 cooling fans?
Hello, Bigdog I have a rondeo isuzu 99 my ac clutch is spinning and new refrigerant is just put in. Hot air is still coming out. What do you think it can be and what to look out for?
Nice tips on safety when working around refrigerants. Also observed you using your hand as a shield at 12:49 when connecting to the service port.👍🏻
👍
Hey men on this exact 1997 accord can i replace just the compressor clutch or do i have to replace the entire compressor. My clutch is broken.
I’ve got a 02 civic compressor fan and everything kicks on like it should I’ve recharge it but still not blowing cold at all any tips?
Hi my 2010 Honda Accord Crosstour won't blow cold air. It only has 60,000 miles. I bought it used and the A/C was working when I bought it. What should I start with first to trouble shoot? It seems to blow cool air but just does not cool enough to stay comfortable. I do have a navigation system. thank you for your help.
How often do you change the oil in the recovery machine?
Hey and thks for the great video. Can you provide a link for you sniffer? Im going to trouble shoot an ac leak on my 2010 accord coupe bf it gets too hot. Carck
The A/C temp blowing should be about 43 Degrees if you want to be comfortable. When I bought my 1994 accord that's the temp it was blowing. Is it possible to
get that temp down to 42 Degrees?
so using this video to try and fix my ac, and my fans also don’t work everything you’re saying is the same with my vehicle, with recharging it are the fans hydraulic with the referent?
What year Honda was this? What system would a 2009 Honda V6 have?
Big Dog dropping jewels!!
Hello, I have a real head scratcher. 2014 Honda Accord, AC not working. List of maintenance and parts change. (some due to damage) Condenser, pressure line, pressure switch, 3 each relays, filter, compressor, R134a, ECU. I bought the car in winter, did not drive for 3 months so when I prepped it for registration and inspection found the AC did not work. Replaced the damaged parts and one by one troubleshot. I bench tested the fans, they both worked, jumpered the compressor clutch and it engaged. So the common thread to this was logical, ECU. I removed it from the car to inspect the pins, nothing bent or broken and the plugs looked good. Reinstalled the ECU started the car again and the AC system worked. I shut the car off because I wanted to duplicate the WIN. The system did not function. I systematically unplugged and reset the ECU to find the top plug was the one to reset the system. I went to Honda, they installed a new ECU and they told me it worked perfectly driving out of the shop to the lot. When I jumped in to drive away, no air. So I unplugged and rest the top plug and it worked. I cannot find on the net the exact wiring diagram for the top plug and what parts of the car it controls. It is obvious that by resetting the plug something in the car resets to allow the AC to work. If you have any wisdom to offer I would greatly appreciate your time and effort.
Can vacuum test happen with a missing valve?
I have an 97 Honda accord and can't figure out how the fans works. The fans don't kick on without a.c. but with a.c. on both fans come on but doesn't stay on. They cycle every like 10 seconds and turn off ?
Great video. Does the bulb sensor that mounted on the evaporator,monitor the temperature and send signals to the ECM to control the compressor on and off ?
No, the bulb and diaphragm (expansion valve) that was depicted is a mechanical metering device. There is typically an evap temp sensor (attached to the evaporator) that sends the evap temperature to the ECM. When the ECM detects that the evap is too cold it shuts off compressor to prevent evaporator from freezing. Thanks for the comment!
@@BigDog50001 thank you for your explanations
Need help. So driver side blows warm air and passenger side blows cold air. I added ac pro refrigerant and all vents blew cold for 3 days then it reverted back to warm air on driver side and cold air passenger side. If there is a leak why does it not all leak out and blow warm both sides?
I just put a brand new compressor on vacuumed it filled it and it won’t kick on all relays and fuses are good. When I press the ac button the idles changes but nothing else happens I’m so aggravated!
Hey so what will the problem be if I turn on ac and my fans and ac compressor don't turn on its good on freon
What was that particular machine called. That you can use the service
I have a 2000 Honda Accord the ac is blowing hot air I tried to recharge it but for some reason the Freon can still feels full like it didn’t take anything from it at all
Replaced my fans only one worked and now non work as I turn on AC. I replaced and only worked for a short while. I’m curious if the fans don’t work it has to be the relay switch or compressor ?
I’ll check the fuses again
1997 Honda Accord
Got a 1990 ledgend r12 went to 134 ac works then stops then starts gets cold then hot again change all parts on ac what u thing
What If my ac fuse keeps blowing out honda accord 01
Which one is low pressure 😊
What's wrong with 52? They want to freeze in there?
The button on the first panel that let's air in does not light up like yours
Thanks BigDog. On my 2003 Accord Coupe 2.3liter, should both fans always come on with the AC? Thanks.
For 2003 Accord 4 cylinders, there should only be one control for both fan relays so when the relays are grounded both fans should come on.
@@BigDog50001 Thanks BigDog
What should the cost to the driver be at a reasonable mechanic for the things you did?
Hope you can help. I have Accord 2012 K24 and both fans turns on on start up also the compressor engages for a couple of seconds. Then turns off. Not sure if this is normal or default. Appreciate the help
I'm having the same issue on the 2012 accord, did u find out what is the caused?
