my A/C hasent worked for the past couple of months. today i changed my coils out and flushed the cooling system after i was finished i turned on the A/C to see if it works then surprisingly the A/C was blowing cold air but that only lasted for 10 minutes then it went back to blowing warm air. i was told that the heater control valve is bad i am in the processing of ordering that part, but what would make the A/C work then just stop working?
