Power Mirrors
Function Test
1. Remove the dashboard lower cover
(see page 20-69).
2. Push the power mirror switch (A) out from behind
the dashboard.

BLU/GRN
3. Disconnect the 10P connector (B) from the switch,
then remove the switch.
4. Choose the appropriate test based on the
symptom:
• Both mirrors don't work, go to step 5.
• Left mirror doesn't work, go to step 7.
• Right mirror doesn't work, go to step 8.
• Defoggers don't work, go to step 9 (Canada).
Both mirrors
5. 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 (7.5A) 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 6.
6. 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 (G 501).
• If there is continuity, check both mirrors
individually as described in the next column.

7. 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
8. 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)
9. 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 or ORN/WHT wire.
– blown No. 4 (7.5A) fuse in the driver's under-
dash fuse/relay box.
– poor ground (G401 or G581).
• If only one fails to warm up, check its defogger.
• If both warm up, check the defogger switch.
