PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. If the Blower Motor does not operate, check the HVAC BLO MOT Fuse and the HTR-A/C Fuse.

2. If the Blower Motor does not operate:
- Check that grounds G100 and G111 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
