Power Mirror Function Test

1.Remove the driver's switch panel (A).

 

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

3.Choose the appropriate test based on the symptom:

  • Both mirrors don't work, go to 4.
  • Left mirror doesn't work, go to 6.
  • Right mirror doesn't work, go to 7.
  • Defoggers don't work, go to 8.
  • Retract actuators don't work, go to 9.

Both mirrors


4.Check for voltage between the No. 2 terminal and body ground with the ignition switch ON (II).
There should be battery voltage.
  • If there is no battery voltage, check for:
    • blown No. 14 (10A) fuse in the under-dash fuse/relay box.
    • an open in the BLK/YEL wire.
  • If there is battery voltage, go to 5.

5.Check for continuity between the No. 6 terminal and body ground.
There should be continuity.
  • If there is no continuity, check for:
    • an open in the BLK wire.
    • poor ground (G501).
  • If there is continuity, check both mirrors individually as described in the next column.

Left mirror


6.Connect the No. 2 terminal to the No. 10 terminal, and the No. 5 (or No. 12) terminal to No. 6 terminal with jumper wires. The left mirror should tilt down (or swing left) with the ignition switch ON (II).
  • If the mirror does not tilt down (or does not swing left), check for an open in the GRN/WHT (or BLU/WHT) 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 BLU/BLK wire.
  • If the mirror works properly, check the mirror switch.

Right mirror


7.Connect the No. 2 terminal to the No. 11 terminal, and the No. 5 (or No. 13) terminal to No. 6 terminal with jumper wires. The right mirror should tilt down (or swing left) with the ignition switch ON (II).
  • If the mirror does not tilt down (or does not swing left), check for an open in the GRN/WHT (or WHT/RED) 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 RED/YEL wire.
  • If the mirror works properly, check the mirror switch.

Defogger


8.Connect the No. 1 and No. 8 terminals with a jumper wire, and check for voltage between the BLK wire terminal of the mirror connector and body ground. There should be battery voltage and both mirrors should warm up with the ignition switch ON (II).

  • If there is no voltage or neither warms up, check for:
    • an open in the BLK/YEL or ORN wire.
    • blown No. 14 (10A) fuse in the under-dash fuse/relay box.
  • If only one fails to warm up, check its defogger.
    • poor ground (G501, G502).
  • If both warm up, check the defogger switch.

Retractable mirror


9.Connect the No. 2 terminal to the No. 7 (or No. 8) terminal with a jumper wire. The mirrors should retract (or extend) when the ignition switch is turned back and forth between ON (II) and OFF.

  • If the mirrors neither retract nor extend, check for an open in the RED/BLU or RED/WHT wire between the switch and the mirrors.
  • If one of the mirrors does not retract or extend, check the retractable mirror actuator.
