The AC in our 2011 2WD CR-V works fine much of the time. But sometimes it quits blowing cold air and blows warm air from the outside. Local shop checked "freon" and put leak detector fluid in - found nothing. With recharge, it's working better - colder. But still quits while driving and blows ambient air into the cabin. Shop cannot figure it out.

Any ideas?

Worn A/C compressor clutch.

Have the mechanic check the gap. Too big = clutch gets 'tired' and won't pull in all reliably.

Also, the fans need to come on when it's running.

I've read that the relay for the compressor could be failing intermittently. $10 to replace that while I am looking for a competent shop.

I've replaced this a couple of times. Most places will only sell you the whole compressor. Make sure you check which compressor you have and you can find the clutch on eBay or Amazon. A good pair of snap ring pliers is crucial to take out existing clutch but overall it's a easy job.

Thanks for the note!

Try the relay first as from previous messages. I keep a spare in mine as they do go from time to time and it is not expensive. If problem persists you can change the compressor clutch. I found that mine would intermittently come off and on then finally it didn't work at all. If you have to do the clutch there is a youtube video on how to do it.

I bought a new relay. Will put it in today. Should be warm this week so we can test the AC. If that don't fix it, I will dig into the compressor clutch. I appreciate y'all helping me out!
