--Coolant Temp Sensor - may have an input, on EFI if the engine is overheating, the ECU will not allow the A/C to come on, if it doesn't see the Coolant Temp Sensor it will not turn A/C on at all (may have 1 sensor for the gauge & 1 for the ECU)

also check to see if the A/C relay is clicking or turning on, if it is turning on follow the wire up from the compressor and look for stretched/broken wire (may have pulled on something and caused the problem), give a light tug on the wire going into the connector (if it comes out, that was your problem)
