Here's the scenerio......
93 Z28, the a/c is charged and blows cold. it works perfectly about 90% of the time. Sometimes the compressor cuts off and it will not kick back in unless the car is shut off and restarted. Again, the R134a is at the correct level. When this happens you can turn the a/c off and on as many times as you wish and it will not kick back on unless you shut off the engine and restart. It's done this for 2 years and normally it's not a real big deal.
Now my 94 V6 has started to show signs of this. Sometimes when you start the car, the a/c just won't energize the compressor clutch. Turning the a/c off and on again has no effect. Only shutting off the car and restarting clears the problem and everything works perfectly.
My thought is high heat switch, but why would nothing respond unless the motor is shut off and restarted?
