Troubleshooting Hints - 6-Way Power Seats

Procedure

Note: 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 failure but prove "GOOD" in a continuity/voltage check. Use Test Light J 34142 whenever possible. Test lights require more current than a high impedance DVM and are more useful for detecting abnormally high resistive circuits. Some test lights have high impedances and will not be as useful in detecting resistive circuits.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
