Troubleshooting Hints - 6-Way Power Seats

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(s) to ground in 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
