### Circuit/System Verification

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 .

### Circuit/System Testing

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.
