this thing is driving me up the wall!!!for the past 2 summers my ac isnt worth jack.whenever the car gets hot or its hot outside my ac quits working.the compressor shuts off and nada.and for the few min it is working its not cold.then it wont work for a few days then start working again.and it does the same thing.also if i turn it on high.but at night or when its cool out it seems to work fine.last yr i was told it was a bad ground which they say was the pcm.so i bought a new one and its still doing it.i checked the pressure and it was like 1 lb low so i added one and still nothing!!i need help please!its hot in florida.

 

TTT any oneknow anything about ac???none of the shops around here have any clue what they r doing and its just costing me $$ to have them tell me that.
