3. Disconnect the 13P connector (B) from 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.
Defogger doesn't work (Canada), go to step 9.
Both mirrors
S. Check for voltage between the No.2 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. 14 (10A) fuse in the under-dash
fuse/relay box.
- an open in the BLK/VEL wire.
• If there is battery voltage, go to step 6.
6. Check for continuity between the No.6 terminal
and body ground.
There should be continuity.
• If there is no continuity, check for:
- an open in the BlK wire.
- poor ground (GS01).
If there
is continuity, check both mirrors
individually as described in the next column.

Left mirror
7. Connectthe No.2 terminal to the No. 10 terminal,
and the No. S (or No. 12) terminal to the No.6
terminal with jumper wires. The left mirror should
tilt down (or swing left) with the ignition switch ON
(II).
• If the mirror does nottilt down (or does not swing
left), check for an open in the GRN/WHT (or BLU/
WHT) wire between the left mirror and the 13P
connector.
If the
wire is
OK,
check the left mirror
actuator.
If the mirror neithertilts down nor swings left,
repair the BLU/BLK wire.
If the mirror works properly, check the mirror
switch.
Right mirror
8. Connect the No.2 terminal to the No. 11 terminal,
and the No.5 (or No. 13) terminal to the No.6
terminal 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 WHT/
RED) 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 RED/VEL wire.
If the mirror works properly, check the mirror
switch.
Defogger (Canada)
9. Connect the No.1 and No.8 terminals with a
jumper wire, and check for voltage between the
No.2 terminal of the mirror connector 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 BLK/VEL or ORN wire.
- blown No. 14 (10A) fuse in the under-dash
fuse/relay box.
• If only one fails to warm up, check:
- its defogger.
- poor ground (GS01, GS02).
• If both warm uP. check the defogger switch.
