Diagnosis & Testing

When the rear window lockout feature is enabled, the circuit is open and no voltage is supplied to the rear window switches. When the feature is not enabled, the circuit is connected to battery positive voltage. If this circuit is shorted to ground when the lockout feature is not enabled, the PWR WDO circuit breaker may cycle continuously OFF/ON until, either the lockout switch is pressed to open the circuit, or the circuit breaker is permanently damaged. All windows may be partially or totally inoperative while the fault is present.

Inspect for aftermarket devices which could affect the operation of the system. Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom. Faulty electrical connections or wiring may be the cause of intermittent conditions.
