Troubleshooting Hints - Power Windows

1. If all power windows do not operate, check PWR WDO Circuit Breaker for an open. If the Circuit Breaker is blown, check CKT 143 for a short to ground.
2. Check that G301 is clean and tight.
3. If windows only operate from the LF Window Switch, check for approximately B+ at LF Window Switch CKT 143 (2 Door) or CKT 1307 (4 Door).
4. Before performing any diagnostics, make sure the Lock Out Switch is in the "OFF" position (4 Door).
5. Each Window Regulator Motor contains an electronic circuit breaker. The resistance in the Window Regulator Motor increases if the motor is overloaded and the resistance will return to normal after voltage is removed from the motor terminals.
6. A momentary actuation of the Window Switch can cause the window to move directly to the fully open position. When working on the door leave the ignition off whenever possible. Note where the Window Switch is so you do not accidentally hit it. To stop the window, press the LF Window Switch "UP."
^ 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
^ Refer to System Diagnosis.
