WIERD A/C issue - fstty, have you done THIS b4?
Ok, so I got me a little issue.
About a week ago I was driving around with the AC on and then all of the sudden it starts blowing hot air. I turned it off and on, I tried just hitting the AC button, I tried full auto vs. manual all to no avail. The next time I get in my car, the AC is pumping again, and I think the air was actually colder. I tried turning up the temp manually to above the outside temp and it was still really cold air. This stayed the same for for about 2 days. Then it started blowing hot air again.
Basically it's a problem I can't reproduce unless I leave it at the shop for a week. My first thought was I needed more freon, but if that was the case I'd NEVER have cold air.
It's an 03 TLS with 35k miles. I have an appointment for warrenty service, but my fear is they'll come back saying I need a feon recharge and raped on pricing.
Anyone have any thought on this?
Thanks,
Joe

i actually have the opposite problem where if i have the heat on for a while it begins blowing cool air. so i usually crank the heat up a few notches and it resumes. hmm, i wonder if i need a new control unit as well. my a/c is cold as hell though.
