System Testing

NOTE: If both mirrors are inoperative, begin testing at step 1). If one mirror is inoperative, begin testing at step 3).
  1. Turn ignition on. Check hazard flasher/stoplight fuse. If fuse is blown, replace fuse (repair wiring if necessary). If fuse is okay, check voltage at Light Green/Yellow wire terminal of power mirror switch connector. If battery voltage is not present, repair Light Green/Yellow wire.
  2. If battery voltage is present, check continuity between ground and Black wire terminal of power mirror switch connector. If there is no continuity, repair Black wire. If there is continuity, go to next step.
  3. Disconnect power mirror switch connector. At power mirror switch connector, apply battery voltage between Yellow wire terminal and specified wire terminal. See POWER MIRROR CIRCUIT TEST table. If power mirrors operate, replace power mirror switch. If power mirrors do not operate, check wiring between power mirror switch and power mirror motor. If wiring is okay, replace power mirror motor.
