Power Mirror Function Test
NOTE: The right power mirror is controlled by the front passenger's power window switch. When the power mirror switch is operated, the power window master switch receives the signals from the power mirror switch and sends the signals to the front passenger's power window switch. If there is a malfunction with the right power mirror actuator operation, do the power window master switch input test and front passenger's power window switch input test. Also, the power mirror defoggers are controlled by the power window master switch and the front passenger's power window switch, do the power window master switch input test and front passenger's power window switch input test.

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.
Both Mirrors

3.
Measure the voltage between terminal No. 4 and body ground with the vehicle ignition in the ON mode. There should be battery voltage.
If there is no battery voltage, check for:
?
Blown No. B1 (7.5 A) fuse in the under-dash fuse/relay box.
?
An open in the LT GRN wire.
If there is battery voltage, go to step 4.

4.
Check for continuity between terminal No. 13 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, go to step 5.
Left Mirror

5.
Connect terminals No. 4 and No. 9, and terminals No. 1 (or No. 7) and No. 13 with jumper wires, and vehicle ignition ON mode.
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 YEL) 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 PUR wire.
If the mirror works properly, check the mirror switch.
