[mikewinkler]

Thank you so much. Just bought a 2003 and get hot air and you took the time to explain it very clearly. Very helpful.

This worked on my sons 2007 Accord after it my honest mechanic diagnosed the faulty relay on my other sons 2006 civic about a year ago ($30 diagnosis and repair)! Took the relay to auto zone and the tech said this was the most common problem he sees on many of the 2000s era honda A/Cs. Thanks for this posting!

THANK YOU SIR for this helpful information. I fixed my AC problem in less than 30 minutes. All those mechanic scams will be out of business soon because of your good heart advise.

Thank you so much!!! It was the relay on my 03 Accord

Great job very informative straight to the point thank you

[jeremygast]

Thanks for explaining what happens if it's not sending power to the compressor

[capenafuerte]

Very thorough, and informative post. Will troubleshoot my 2003 Honda Accord which is experiencing AC issues. Thank you.

I see you're not answering people's comments but what the heck, maybe someone else can help. At 2:55 you mentioned the 7.5A fuse provides constant power to the relay. I checked Voltage to that fuse's socket with a multimeter and no voltage. The fuse is not blown. It's not getting power, what is my next step?

Big time helpful, I was sitting at work and my air stopped blowing cold almost immediately. These tips will help me track down the problem. Quick question, was the clip for the compressor power cable mounted? I think mine has a clip in place right beside the fan??

Found the fuse hole due to misplaced. Thx man...

Good mechanical diagnostic skills man. My girlfriend has 2004 Honda Accord and I'm praying the cabin filter is the reason hers doesn't work. Freon is charged and radiator coolant is topped out and fresh. Do you have any suggestions? Thanks in advance. Five star video. Subbed

[rinserepeat]

Great video QUESTION- where on the compressor was that wire found? I see the wire but is the plug up on top of compressor? Also, can you do a video on measuring the one pin plug connected to compressor, or in a quick response. Thank you for explaining this seeming easy diagnosis. subscribed!!

So I have the exact same car as in the video.. I checked all fuses and 7.5 is good, on the relay for the compressor I’m only getting light on my test light at one of the 4 slots in my fuse box… I’m guessing that’s the constant power slot for the pins on the relay .. also checked the wire like you did in the video where power goes from the relay and then into the compressor but not getting any power at that point on the wire connector there at that plug …. Compressor won’t come on and just blows hot air … I know you said if you DO get power at that connector then it is prob the compressor but what if you don’t get power there ? Oh I also took another relay out and swapped it with but still nothing …

NICE info....power to the compressor is good, but that doesn't mean BAD compressor. Honda clutches can go @ 80 k... way easier fix than pulling compressor as just grinding it down a very small amount can reengage clutch... Power to it test was nice to see... 134a & relay & compressor said shop for $1100

Excellent video. I just checked my fuses and they all appear to be fine, my compressor turns on well, the condenser is great and the system is fully charged, but it will not blow any cold air whatsoever. The cabin filter is clean and the intake filter is clean. About 5 years the entire system was replaced and all of a sudden it just stopped blowing cold air and I am clueless. Have you ever heard of this issue? After watching your video I was thinking maybe it was the relay, but if it was that then no circuit would be sending for the compressor to turn on.

WOW ..thanks men, I guess I will have to ck that fuse inside the car bcz sometime the 2 fans n the ac work and sometimes they don’t work in the same time ...can’t tell why ..one week all good and one week all stops !!!!any idea what could it be

Varia la caja de fusibles de un v6 a un v4 2003

[alexsimental]

If my compresor works but still doesnt provide power to the other parts of the ac system (fans, blower, etc) what else could be?

[mattthibault]

Tyvm for this video. My car had a bad relay, what an easy fix!

[elizabethhousel]

thanks for the video! Honda Accord EX 2004 30, 000 miles
All at once no lights, front wipers, turn signals and a/c is blowing hot air. checked all fuses- and relay switch. All good, the only thing I can see is the compression Clutch the plate on the side is not spinning, the compressor is I think I am out of my league now
Guess it's time to take it in...
