Hey all, I'm new here and having a problem. I replaced my a/c compressor(and dryer/orfice tube) the bearings were going out on the old one(replaced 13 months ago). Anyway, I replaced all the equipment and took the car to be evacuated and charged. The mechanic couldn't get the compressor to come on. He was able to b/p and turn on the compressor to charge, but the car will not turn the unit on automatically. Any ideas where to go next, besides the dealer?

first of all what kind of car?or???????????
