check your fuse box for a blown ac fuse, fuse box usually under dash, sometime under the hood of the car usually on drivers side. bad switch? check if you hot wire lead might be pinched and grounded out or broken wire between battery and switch
YOU COULD HAVE OPEN OR SHORT IN THE BLACK YELLOW WIRE GOING TO AC COMPRESSOR CYCLING PRESSURE SWITCH. CHECK FOR A SHORT OR OPEN IN RED YELLOW WIRES AT THE AC PRESSURE CUTOFF SWITCH. USE VOLT METER AND CHECK FOR VOLTAGE AT BOTH SWITCHES. PROBLEM COULD BE IN THE EATC MODULE THAT SEND POWER TO PURPLE WIRE THAT FEEDS THE AC PRESSURE CUTOFF SWITCH AND AC CLUTCH CYCLING PRESSURE SWITCH THEN FEEDS THE AC COMPRESSOR CLUTCH SOLENOID.
the compressor is also controled by the coimputer. Disconnect the battery than reconnect it than try your ac to see if it comes on. if it does and it clicks on and off than you may be low on freon. Being low on freon will also keep the compressor from coming on because you have pressure switches that are in ac lines that control power to the compressor. you can disconnect the wires at the compressor and with the car running turn the ac on and probe the wire with a test light to see if you have power to the compressor. If you have power than chances are your ac clutch may be bad. Hope this helps leave a comment.
Could be,but make sure the ground side of the compressor(wire)is grounded,if it is,the clutch coil on the compressor is bad,it will be cheaper,and easier,to replace the compressor with the clutch assembely.
