check the low side switch located on the ac receiver drier for 12 volts if so jump it with a paper clip if the compressor comes on then the relay is good if not the relay is in the fuse junction box under the hood.Most likely the pressure sensor.

Check the A/C pressure in the line, you should have 100-105PSI with the engine not running and if you have less then 45 PSI in your system. The A/C will not activate to ensure the compressor does not seize when the clutch activates.
Thank you for using Fixya and good luck

Check the Aircon pressure switch, try another if possible. Switch located on Aircon condenser behind front bumper. Either a to high or to low pressure in the system will prevent the compressor from engaging. Pressure switches do go faulty at times.

Check to see if the wires on the fan module are corroded. The fan module is under the battery. Easier to see from under vehicle. Also check the fuses first.
