Power Mirror Function Test

Power Mirror Function Test

1. Remove the power window master switch. Power Window Master Switch Test/Replacement

2. Disconnect the 13P connector (A) from the power mirror switch (B).

3. Choose the appropriate test based on the symptom:
- Both mirrors don't work, go to step 4.

- Left mirror doesn't work, go to step 6.

- Right mirror doesn't work, go to step 7.





Both mirrors

4. Measure the voltage between the terminal No. 2 and body ground with the ignition switch turned to ON (II). There should be battery voltage.
- If there is no battery voltage, check for:
- Blown No. 36 (10 A) fuse in the under-dash fuse/relay box.

- An open in the BRN wire.

- If there is battery voltage, go to step 6.

5. Measure the continuity between the terminal No. 6 and body ground.
There should be continuity.

- If there is no continuity, check for:
- An open in the BLK wire.

- Poor ground (G503).

- If there is continuity, check both mirrors individually.

Left mirror

6. Connect terminals No. 2 and No. 10, and terminals No. 5 (or No. 12) and No. 6 with jumper wires.
The left mirror should tilt down (or swing left) with the ignition switch to ON (II).

- If the left mirror does not tilt down (or does not swing left), check for an open in the PUR (or PNK) wire between the left mirror and the 13P connector.
If the wire is OK, check the left mirror actuator.

- If the mirror neither tilts down nor swings left, repair the GRN wire.

- If the mirror works properly, check the mirror switch.

Right mirror

7. Connect terminals No. 2 and No. 11, and terminals No. 5 (or No. 13) and No. 6 with jumper wires. The right mirror should tilt down (or swing left) with the ignition switch to ON (II).
- If the mirror does not tilt down (or does not swing left), check for an open in the PUR (or BLU) wire between the right mirror and the 13P connector.
If the wire is OK, check the right mirror actuator.

- If the mirror neither tilts down nor swings left, repair the WHT wire.

- If the mirror works properly, check the mirror switch.

Defogger (With mirror defogger)

8. Connect the power mirror defogger relay terminals No. 1 and No. 2 in the under-hood fuse/relay box with a jumper wire, and measure the voltage between terminal No. 1 of the mirror connectors and body ground. There should be battery voltage and both mirrors should warm up with the ignition switch to ON (II).
- If there is no voltage or neither warms up, check for:
- An open in the ORN wire.

- Blown No. 36 (10 A) fuse in the under-dash fuse/relay box.

- If only one fails to warm up, check:
- Its defogger.

- Poor ground (G503).

- If both warm up, check the defogger switch.
