Troubleshooting Hints

1. If the Blower Motor does not operate, check the BLO Fuse and the HVAC Fuse by visual inspection.
2. If the Blower Motor does not operate, check that grounds G112 and G204 are clean and tight. Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove good in a continuity/voltage check. Refer to Troubleshooting Procedures.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems. Refer to Troubleshooting Procedures. Diagnostic Aids
