Preliminary Checks

  1. Using a scan tool, check for Diagnostic Trouble Codes (DTCs) related to the A/C heater module, Body Control Module (BCM), PCM and PDC. If no DTC is found, go to Step 2. If a DTC is found, repair as required.
  2. Check the A/C clutch fuse in the PDC. If OK, go to Step 3. If not OK, repair the shorted circuit and replace the fuse.
  3. If the A/C clutch still will not engage, verify the refrigerant charge level by conducting the A/C Performance test. Refer to DIAGNOSIS AND TESTING . If the refrigerant charge level is OK, go to COIL RESISTANCE TEST and COIL CURRENT DRAW TEST below. If the refrigerant charge level is not OK, adjust the refrigerant charge as required.
