Check for a fuse that indicates radio and replace it if it's burnt through or melted or discolored. The Buicks have dash controls that require expensive repairs sometimes to get the temperature controls to work so some people jump around the controls by installing a separate toggle switch that directly turns the AC unit off and on for 92 through 94 Buicks. Any AC shop can install the bypass wires.
CHECK RADIO AND LIGHTER FUSE.FOR THE AIR CONDITIONER CHECK TO SEE IF AC COMPRESSOR CLUTCH ENGAGING AND RUNNING WHEN YOUR CAR ON DEFROST IF NOT CHECK COMPRESSOR FUSE AND RELAY.IF FUSE AND RELAY GOOD.POWER GOING TO COMPRESSOR.THE COMPRESSOR CLUTCH OPEN OR REFRIGERANT LEVEL LOW OR FAULTY PRESSURE CYCLING SWITCH.ITS LOCATED ON A SCHRADER TYPE VALVE AT THE ACCUMULATOR.IF ALL IS GOOD AC COMPRESSOR WORKING ON DEFROST AND DEFOG ONLY.YOUR AC CONTROL SWITCH IS BAD OR YOUR AIR DOOR NOT OPEN DUE TO NO VACUUM.COULD BE BROKEN VACUUM OR IF YOU HAVE CLIMATE CONTROL YOUR PROGRAMMER OUT OF CALIBRATION NOT ALLOWING AIR MIX DOOR TO OPEN.IF YOU HAVE CLIMATE CONTROL DEALERSHIP HAS TO FIX IT.
