(65,000 miles) The heater works fine but there is no air conditioning. It was refilled with freon last year which worked for awhile but then again no cold air. The shop said there was no leak. Any ideas. Can't handle another summer in Texas w/o air.

If the heat works and not the air is there just a switch that can be replaced? Hammer Time Ultimate Carjunky / Moderator Feb 13, 2011, 9:12 PM Post #4 of 5 (3249 views) Re: Heat but no AC Sign In It not only means a whole compressor but a bunch of related stuff that goes with it too. No matter what goes wrong with an A/C system, the result is the same, no cold air. It needs to be checked out by a competent technician. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Know that about 65% of A/C not blowing cold is or starts with low charge of refrigerant from wherever it leaks. Finding leaks can be tricky and my guess is compressor's shaft seal is more likely in the warmer climates then where I am in MA with a shorter cooling season. Should be no shortage of qualified shops in TX to do the job right. I strongly suggest if compressor is the fault to go new not rebuilt ones. As HT said if a compressor is needed there are other things that are usually needed and it can get pretty pricey. Might get lucky and it's something simple but it's not a trade for everyone nor very DIY friendly. Just don't fall for the "magic in a can" fix stuff sold everywhere as it both rarely works and makes the real fix that much more costly.
