You can at least make sure it's nothing as simple as a blown fuse. Open the hood and run the engine and a/c. Locate and observe the compressor, which is run by the serpentine belt, in the lower corner nearest the radiator. If the pulley only free wheels and the center part doesn't engage and disengage, find the fuse in the box either in the engine compartment or under the dash and locate the a/c fuse. The compressor clutch is electromechanical. If it cycles on and off frequently, you may have low coolant, a leak, blockage or bad compressor. Obviously, the first possibility, low coolant, is the easiest to diagnose and fix, and it goes on up from there. Good luck.
