Power Mirrors Inoperative

  1. Review operation of power mirrors. See DESCRIPTION & OPERATION  . After review, go to next step.
  2. Place left side door window/mirror switch to LEFT position. Activate to UP, DOWN, LEFT and RIGHT positions. Place left side door window/mirror switch to RIGHT position. Activate to UP, DOWN, LEFT and RIGHT positions. If both mirrors operate, test wiring system for intermittent and poor connections. If both mirrors do not operate, go to next step.
  3. If both left and right mirrors are inoperative, go to next step. If either left or right mirror operates, go to step  6 .
  4. Disconnect left side door window/mirror switch harness connector. Connect a test light between ground and left side door window/mirror switch harness connector terminal No. 11 (Brown wire). If test light illuminates, go to next step. If test light does not illuminate, go to step  7 .
  5. Connect a test light between left side door window/mirror switch harness connector terminals No. 6 (Black wire) and 11 (Brown wire). If test light illuminates, go to step  9 . If test light does not illuminate, go to step  15 .
  6. Disconnect suspect power mirror harness connector. Connect a test light between suspect power mirror harness connector motor control circuits. See WIRING DIAGRAMS  . Place left side door window/mirror switch to suspect power mirror. Activate suspect power mirror in all positions. If test light does not illuminate in all positions, go to step  8 . If test light illuminates in all positions, go to step  12 .
  7. Inspect Brown wire for an open or short to ground. If problem is not found, go to step  9 . If problem is found and corrected, go to step  18 .
  8. Inspect mirror motor control circuits for an open. See WIRING DIAGRAMS  . If problem is not found, go to next step. If problem is found and corrected, go to step  18 .
  9. Connect power mirror harness connectors, if previously disconnected. Disconnect left side door window/mirror switch harness connector, if not already disconnected. Connect a test light between battery voltage and left side door window/mirror switch harness connector motor control circuits. See WIRING DIAGRAMS  . If test light does not illuminate at any terminal, go to next step. If test light illuminates at all terminals, go to step  13 .
  10. Connect a test light between ground and left side door window/mirror switch harness connector motor control circuits. If test light does not illuminate at any terminal, go to next step. If test light illuminates at all terminals, go to step  14 .
  11. Inspect left side door window/mirror switch harness connector for poor connections. If problem is not found, go to step  16 . If problem is found and corrected, go to step  18 .
  12. Inspect power mirror harness connectors for poor connections. If problem is not found, go to step  17 . If problem is found and corrected, go to step  18 .
  13. Repair short to ground in mirror motor control circuit. After repair, go to step  18 .
  14. Repair short to voltage in mirror motor control circuit. After repair, go to step  18 .
  15. Repair open in Black wire between ground and left side door window/mirror switch. Ground point is located at base of left "A" pillar. After repair, go to step  18 .
  16. Replace left side door window/mirror switch. After repair, go to step  18 .
  17. Replace power mirror motor, then go to next step.
  18. Operate system to verify repair. If system is not operating correctly, repeat test beginning at step  2 .
