Function Test

  1. Remove the instrument panel (see INSTRUMENT PANEL REMOVAL/INSTALLATION ).

  2. Choose the appropriate test based on the symptom:
    • Both mirrors do not work, go to step 3.
    • Left mirror does not work, go to step  5.
    • Right mirror does not work, go to step  6.
    • Mirror defoggers do not work, go to step  7.

    Both mirrors 

  3. Check for voltage between terminal No. 2 and body ground with the ignition switch ON (II).

    There should be battery voltage.

    • If there is no battery voltage, check for:
      • A blown No. 10 (7.5 A) fuse in the under-dash fuse/relay box.
      • An open or high resistance in the RED wire.
    • If there is battery voltage, go to step 4.
  4. Measure the voltage between terminal No. 6 and body ground while you operate the mirrors. There should be less than 0.2 V.
    • If there is 0.2 V or more, check for:
      • An open or high resistance in the BLK wire.
      • Poor ground (G501).
    • If the voltage is as specified, check both mirrors individually.

    Left mirror 

  5. Connect power mirror switch 13P connector terminals No. 2 and No. 10, and terminals No. 5 (or No. 12) and No. 6 with jumper wires, and turn the ignition switch to ON (II).

    The left mirror should tilt down (or swing left).

    • If the left mirror does not tilt down (or does not swing left), check for an open or high resistance in the GRY (or RED) 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 ORN wire.
    • If the mirror works properly, check the mirror switch.

    Right mirror 

  6. Connect power mirror switch 13P connector terminals No. 2 and No. 11, and terminals No. 5 (or No. 13) and No. 6 with jumper wires, and turn the ignition switch to ON (II).

    The right mirror should tilt down (or swing left).

    • If the mirror does not tilt down (or does not swing left), check for an open or high resistance in the GRY (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 LT GRN wire.
    • If the mirror works properly, check the mirror switch.

    Defogger 

  7. Connect rear window defogger relay terminals No. 1 and No. 2 with a jumper wire. Measure the voltage between terminal No. 2 [No. 1] of the mirror connectors and body ground. There should be battery voltage and both mirrors should warm up.

    • If there is no voltage or neither warms up, check for:
      • An open or high resistance in the BRN wire.
      • A blown No. 55 (10 A) or No. 59 (40 A) 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 climate control unit or the rear window defogger relay.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
