Preliminary Checks

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
  1. Using a scan tool, check for any Diagnostic Trouble Codes (DTCs). If no DTCs are found, go to Step 2. If any DTCs are found, repair as required.
  2. 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. If the refrigerant charge level is not OK, adjust the refrigerant charge as required.
