Troubleshooting Hints - Blower Controls

1. Check for missing or damaged connector seals at the blower motor resistor and blower motor relay
2. Check HTR A/C Fuse 6 if the blower motor is inoperative. If open, check for short to ground through CKT 141.
- Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
- Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
