Test Description

Step 1 - Step 11:

The number below refers to the step number on the diagnostic table.
6. This step ensures that the power window master switch lockout signal circuit is not the cause of the malfunction. This circuit supplies battery positive voltage, through the rear window lockout switch, to the rear window switches, and is used to enable or disable the rear window lockout feature. 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.
