My ac has never been the best on my 85.5 944, but we had it serviced a year ago and it was ok until yesterday. One thing I had always noticed was that when driving in long streaches of shade (tunnel, overhanging trees) it worked better and when the right front tire ran through a puddle it worked grreat. Last night driving home it was running really cold (it was dark.) Then, we got hot hot hot air. We got that to stop but now the air will not even think about getting cool enough to keep one comfortable. I checked the 134 and topped it off, no luck. I understand there are 3 temp sensors that help the ac do its thing. One is in the dash, where are the other two? I suspect and have read that one is near the wheel well. That makes sense with the puddle thing. Can anyone help me with where the 2 are I cannot locate and what they look like and how to test all of them or bypass them?
