my a/c quit
Hello,
I have on 03 H2 with 44k miles. My ac quit blowing cold yesterday. I was wondering if there was any issues with this or if i just need to take it in and get it charged. It blows hot. Can't think of anything else that it could be than just needing a recharge.
thanks for you help

Re: my a/c quit
Check some of the obvious things first before paying for a recharge such as the fuse for the compressor (its got an electronically controlled clutch) and then check to see if the compressor is even engaging

Re: my a/c quit
are the other functions of the hvac control panel working correctly? I'd try the other things mentioned on the thread.

Re: my a/c quit
Yep is all works fine, just doesn't blow cold. The belt looks fine. I check the fuse on the side of the dash. Is that the fuse that you guys are talking about? just thought that is was odd with only 44k miles, but i guess it is 5 years old. Thanks guys for the tips, I will check them out.

Re: my a/c quit
If belt is on and pump is pumping when engaged , try adding some freon. Its not freon anymore , its N-12 or something. You can buy a can at Napa for $15. The can has a hose that snaps onto your condenser line , then push top of can and fill system. If a/c doesnt blow cold after that take it to a shop. Only do this after you have checked the fuses , reset the brain , and checked the belt is on. doug
