Having problems with your 2002 Chevrolet Cavalier Coupe ?

I have a 2002 chevy cavelier, trying to charge the ac. The compressor won't start to take in gas. we jumpered the the compressor wires and it starts. So I am replacing the high and low switches. i took the front one off on the condensor and very little pressure was in there. I then took the line off the canister on the fire wall and there was alot of pressure, what does this tell you. Is my front switch on the condensor bad since it does not hold pressure there or what?

\015\012Jumper the Low Pressure switch momentarily w/ the A/C on. If the compressor activates, it means your charge is just below min. pressure requirements to function.\015\012

The mode door on you cavalier is cable driven so it sounds like either the cable has broken, fallen off or the mode door has a problem. Usually when the mode door has the problem it defaults to defrost and wont move. The switch on your dash could also be malfunctioning causing the door to not operate.

\015\012heres my two cents. pop hood stood and watch the throttle linkage while someone else starts it . then have that person turn on the ac. watch the throttle linkage. the ac will put an extra load on the engine and the engine knows that so it will kick up the idle. im not quite sure but maybe it came out of adjustment and by you standing there watching it maybe you find where to adjust. also vacuum leak operated devices such as the one i describe might have had a vacuum hosue come loose or crack.. call around to the good parts stores the ones where the employees have worked there for ever and there old folks . they will give you advice but get more then one opinion . repairs shops dont want you to fix it but the part stores will help more then a repair shop. also get a repair manual for you specific car.sorry i cant help more cause im not there.\015\012 \015\012Thanks for contacting Fixya
