Our 2007 Civic is having an issue with the A/C shutting off. I had it recharged just in case, knowing it probably wouldn't help anything but figuring it could use it anyway. That changed nothing. Researching the issue here on this forum and others, I saw that the compressor relay could go bad and cause the very issue I'm having. I replaced it but it changed nothing, either. I swapped this relay with the compressor/fan relay just to see if that did anything, but again it had no effect.

The A/C will blow cold for a while, maybe 10-15 minutes, and then shut off. After a while it will start to work again, and so on.

I have an appointment tomorrow morning with the dealership but before they take all my money I thought I'd reach out to you folks as a last effort to figure it out and fix it on my own.

Please share any input. Thanks much! I truly appreciate it.

 

Bump.

 

Sounds like maybe a pressure cycling switch issue. Do we have those on these cars? It's basically freezing up, then thawing out, then freezing, etc.

 

Sounds worth looking into.

The dealership found nothing wrong, which is what I was afraid of. When it's working, it's working, so I was thinking that their diagnostic machines would probably just report no issues, which is what they did. The problem still exists, however, so if anyone has any more input I'm all ears. Very unchill (pun intended) to not have working A/C.
