2. Disconnect the 10P connector from the power
mirror switch.
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.
• Defogger doesn't work (Canada), go to step 8.
Both mirrors
4. Check for voltage between the No. 1 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. 4 (7.5 A) fuse in the driver's under-
dash fuse/relay box.
- an open in the YEL/BLK wire.
• If there is battery voltage, go to step 5.
5. Check for continuity between the No. 2 terminal
and body ground.
There should be continuity.
• If there is no continuity, check for:
- an open in the BLK wire.
- poor ground (G551).
• If there is continuity, check both mirrors
individually as described in the next column.
Left mirror
6. Connect the No. 1 terminal to the No. 7 terminal,
and the No. 4 (or No. 9) 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 BLU/WHT (or BLU/
ORN) 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 BLU/GRN wire.
• If the mirror works properly, check the mirror
switch.
Right mirror
7. Connect the No. 1 terminal to the No. 8 terminal,
and the No. 4 (or No. 10) 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 BLU/WHT (or LT
GRN) 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/WHT wire.
• If the mirror works properly, check the mirror
switch.
Defogger (Canada)
8. Connect the No. 3 and No. 6 terminals with a
jumper wire, and check for voltage between the
No. 3 terminal 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 YEL/BLK and ORN/WHT wires.
- blown No. 4 (7.5 A) in the driver's under-dash
fuse/relay box.
- poor ground (G551, G581).
• If only one fails to warm up, check its defogger.
• If both fail to warm up, check the defogger switch.
