Try checking the fuse's, if the fuse's are good it could be a bad blower motor.

UNPLUG THE A/C CONNETOR ON THE A/C COMMPRESOR. REPLACE THE FUSE AND TURN ON THE SWITCH. FUSE OK . REPLACE THE COMMPRESSOR AND THE RECIVER DRIER.

hi,
you can try and jump the high pressure limiter switch on the expansion tank, sometimes they get a bubble. Its the silver cylinder looking thing near the firewall. follow the cooling pipes from the compressor back to the tank if theres a question, on the top or near it will be two wires going into it, undo that switch housing connector and hook a jumper wire up there. switch may have to be replaced there. dont run that for any length of time with the jumper, just to diagnose.
good luck

you don't have enough pressure in your system. odds are you have a leak someplace and the factory installed a saftey switch to keep the ac from running when there is no pressure. This way you don't end up burning up your compressor.
