Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

The power window/mirror switch supplies power when requested to the relative power window and also controls the rear power window lock/unlock function. The power window/power mirror switch power supply is controlled by the RAP (retained accessory power) relay. RAP is delivered via the 2A RAP control fuse and the 20A power windows circuit breaker, ground is supplied via ground point G305.

1. Verify that the Retained Accessory Power (RAP) circuit is functioning normally.

⇒	If the RAP is not functioning normally refer to Retained Accessory Power (RAP) Description and Operation .

1. Disconnect the power window/mirror switch harness connector.
2. Verify less than 1 ohm of resistance from the ground circuit terminal and ground.

⇒	If the resistance is greater than the specified value, repair the ground circuit for an open/high resistance.

3. Ignition ON, test for 12 volts between the RAP fuse supply voltage circuit terminal X1-10 and ground.

⇒	If the voltage is not between 9-16 volts, repair the RAP fuse supply voltage circuit for an open/high resistance.

4. Ignition OFF, connect the power window/mirror switch harness connector.
5. Ignition ON, rear window lock-out not selected, verify that at least one of the rear windows operates correctly.
6. If all circuits test normal and the rear windows remain inoperative, replace the power window/mirror switch.
