When the Temp is over 90 the compressor does not receive the signal to turn on. Most of the time if I keep turning it on and off the compressor will kick in and the car will cool. There are times when if I just let it run it will kick in by it self. Before it kicks in the fan will blow on high (hot air). I have replace the heater / AC switch in the dash with a used one and the results is the same. Does anyone have a idea as to what the problem is?
