I am having some A/C problems in my 89 Chevy Blazer and I figured id ask here since the systems are pretty much the same. Well I put this in the Electrical section because i think the problem is electrical. If i turn the A/C on the compressor kicks on but doesn't kick off and back on like it is supposed to, it just keeps running. The A/C is blowing cold at this point until the compressor kicks off but doesn't kick back on. It just stays off untill I turn the switch off and back on again. It blows cold but not so much at idle off idle it is pretty cold. I already changed the relay, the pressure switch located on the dryer bottle, and the A/C control switch (the one that controls the blower motor, A/C Heat Defrost, and Hot and Cold). So any suggestions?
