There is also a high pressure switch on the back of the compressor and sometimes one on the liquid/high side line. If they overcharged it, maybe its keeping the compressor locked out. Also make sure the switches/buttons on the controls are working. There is also a relay for the compressor clutch, they have been known to fail.
