Troubleshooting Hints - Driver 6-Way

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. Check DEFOG/SEATS Circuit Breaker #12 by operating the Rear Defogger.
2. Check that ground G305 is clean and tight.
3. Check for poor connections at Power Seat Switch Connector or Motor Assembly connections.
4. If DEFOG/SEATS Circuit Breaker opens whenever the Power Seat Switch is operated, check for short to ground through CKTs 282, 283, 284, 285, 286 and 287. Disconnecting motors one at a time can be helpful.
^ 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 (refer to Troubleshooting Procedures). Diagnostic Aids
