Troubleshooting Hints - Power Windows

1. If windows only operate from the LH Front Window Switch, check for approximately B+ at LH Front Window Switch Connector C1 terminal "D" (4 Door).
2. Check that Ground G302 is clean and tight.
3. If all power windows do not operate, check POWER WINDOW Circuit Breaker "C."
4. Before performing any diagnostics, make sure the Lockout Switch is in the "OFF" position (4 Door).
- 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 General Troubleshooting Procedures). Diagnostic Aids
