Power Mirror Malfunction

The outside rearview mirror switch controls the outside rearview mirrors based on the position of the mirror selector switch and which movement position is selected. The outside rearview mirror switch has four positions: up, down, left, and right. B+ is applied to the switch from the power mirror fuse and when a movement position switch is selected, voltage is sent to the commanded mirror via a mirror control circuit. The opposite mirror control circuit acts as a ground circuit for the bi-directional mirror motor. Ground is the applied through the switch.

1. Ignition ON, with the mirror selector switch in the driver position, command the mirrors UP, DOWN, LEFT, and RIGHT using the mirror directional switch. The A9A Outside Rearview Mirror - Driver should move in the commanded direction.
2. With the mirror selector switch in the passenger position, command the mirrors UP, DOWN, LEFT, and RIGHT using the mirror directional switch. The A9B Outside Rearview Mirror - Passenger should move in the commanded direction.

1. Ignition OFF, disconnect the X1 harness connector at the S52 Outside Rearview Mirror Switch.
2. Wait 1 minute, test for less than 10 Ω between the ground circuit terminal 5 and ground.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 4 and ground.

⇒	If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

4. Ignition OFF, connect the harness connector at the S52 Outside Rearview Mirror Switch.
5. Disconnect the wiring harness plug at the appropriate outside rearview mirror.
6. Connect a test lamp between the control circuit terminal A and the control circuit terminal B.
7. Operate the vertical switch UP and DOWN. The test lamp should turn ON when commanding the UP and DOWN states.

⇒	If the test lamp remains OFF during either of the commands, test for a short to voltage, short to ground, or an open/high resistance on the control circuits. If the circuits test normal, replace the S52 Outside Rearview Mirror Switch.

8. Connect a test lamp between the control circuit terminal A and the control circuit terminal C.
9. Operate the horizontal switch LEFT and RIGHT. The test lamp should turn ON when commanding the LEFT and RIGHT states.

⇒	If the test lamp remains OFF during either of the commands, test for a short to voltage, short to ground, or an open/high resistance on the control circuits. If the circuits test normal, replace the S52 Outside Rearview Mirror Switch.

10. If all circuits test normal, test or replace the outside rearview mirror.
