1. On the side which has the inoperative mirror, remove the black plastic escutcheon form the trim panel side of the door.
2. Disconnect the electric control outside rearview mirror electrical connector.
3. Turn ON the ignition, with the engine OFF.
4. At the electric control outside rearview mirror connector, connect a voltmeter between terminal 4 and terminal 1, if testing the driver side, or terminal 3, if testing the passenger side.
5. Operate the in/out adjustment on the switch, and record the voltage indicated in each switch position.
6. Connect a voltmeter between terminal 4 and terminal 5, if testing the driver side, or terminal 7, if testing the passenger side.
7. Operate the up/down adjustment on the switch, and record the voltage indicated in each switch position.

Does the voltmeter measure within the specified voltage range for each test, with the polarity reversing when the switch is changed from in to out or up to down?

11-14 V
