I know this is an old thread, but, my AC will start to blow warm/hot air if at idle for more than 2-3 minutes. I recharged the system, didn't take much, and PSI is about 55lbs. It's cold when cruising.
The other day the car started to run hot after idling for 5-10 minutes (Hot Florida sun). Coolant was a bit low and it took about 1 quart of coolant...has been OK since...
The issue seems to be that both radiater/cooling fans will turn off after the car idles for more than a couple of minutes.
Anyone else experienced this problem? I'm thinking maybe the fan relay is bad and where is it located?
