Troubleshooting Hints - Power Windows

Perform before beginning System Diagnosis
1. If both windows are inoperative, check windows Circuit Breaker 15 for open. If open, check for short to ground through CKT 341.
^ Check for poor connection at C200 terminal "E11".
2. If windows move slowly, check that:
- Windows free of mechanical binding and pivot joints and tracks are properly lubed.
- Battery is fully charged.
- Ground G200 is clean and tight.
3. If the Express Down Feature does not work, but window moves down with each switch depression, check for poor connection at Express Down Module terminal "A" or open in CKT 164 from Express Down Module to S263.

^ 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 he 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 "General Troubleshooting Procedures,)". Diagnostic Aids
