Pontiac Repair: a/c not working, refrigerent, cluth

Question
93 sunfire compressor doesn't engage changed relay. any suggestions?

Answer
Hi Mike:
is the system full of refrigerent? If it's low on a charge the system will not work. You could have a faulty cluth on the compressor. if it's full on a charge unplug the compressor and attach the connector to a 12 volt test light turn the car on with the a/c on and see if the light lights if so the clutch is bad.
