Air conditioner keeps blowing the pop off on the compressor
Question:
I have a 1993 Ford Ranger 4.0 the air conditioner keeps blowing the pop off on the compressor. It will work OK for about 15 min. good cold air then will popping off untill empty of freon.
Answer:
That blow off valve is a safety feature because the system had built up enough pressure to explode something.
You need to use a set of pressure gauges and determine why this is happening. You could have many different possible causes including too much refrigerant, restriction in the system, insufficient air flow over the condenser, etc.
