Mirrors: Testing and Inspection
Function Test1. Remove the instrument panel.
2. Disconnect the 10P 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. Check for voltage between the No. 9 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. 16 (7.5 A) fuse in the under-dash fuse/relay box,
- An open in the BLK/YEL wire.
- If there is battery voltage, go to step 5.
5. Check for continuity between the No. 10 terminal and body ground. There should be continuity.
- If there is no continuity, check for:
- An open in the BLK wire.
- Poor ground (G401,G402).
- If there is continuity, check both mirrors individually as described in steps 6 and 7.
Left mirror
6. Connect the No. 9 terminal to the No. 7 terminal, and the No. 5 (or No. 4) terminal to body ground 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 10P connector. If the wire is OK, check the left mirror actuator.
- If the mirror neither tilts down nor swings left, repair the YEL/BLU wire.
- If the mirror works properly, check the mirror switch.
Right mirror
7. Connect the No. 9 terminal to the No. 6 terminal, and the No. 5 (or No. 3) terminal to body ground 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 RED) wire between the right mirror and the 10P connector. If the wire is OK, check the right mirror actuator.
- If the mirror neither tilts down nor swings left, repair the YEL/GRN wire.
- If the mirror works properly, check the mirror switch.
