Hello, I have a 94 Z28 that the air conditioner doesn't work in. I wanted to test the compressor first to see if it is the problem. I have checked the pressure and it has a charge and now I need to find if it's a control problem or if its just the compressor that needs replaced. Looking at the wires that go to the compressor I see three wires and I didn't want to cross two positive wires that might damage more than is already in need of repair. Does any one out there know how to jump the compressor or check if there is an voltage getting to the compressor? Any help would be appreciated. Thanks Matt

 

Do not repair from youself , you should take the car to the servicing center because they knew it better than us , if you will do it by yourself it can create another problem and give you more trouble , so precaution is better than cure .

 

If the the air conditioner is on but it cant produce cool air. You need to refill the refrigerant
