4. Reconnect the 2P connector.
5. Check for continuity between seat-cushion heater
3P connector (male terminals) terminal No. 1 and
seat-back heater 2P connector (female terminals)
terminal No. 2, and seat-cushion heater 3P
connector (male terminals) terminals No. 2 and
No. 3. There should be continuity.
6. If the continuity is not as specified, replace the
appropriate seat heater.
1. Remove the front passenger’s seat (see page
20-118).
2. Disconnect the 3P connector (A) from the seat
heater.
3. Check for continuity between seat-cushion heater
3P connector (male terminals) terminals No. 1 and
No. 3, and seat-cushion heater 3P connector (male
terminals) terminals No. 2 and No. 3. There should
be continuity.
4. If the continuity is not as specified, replace the seat
heater.

1. Remove the power window master switch (A).
2. Disconnect the 13P connector (B) 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.
4. Measure the voltage between terminal No. 2 and
body ground with the ignition switch turned to ON
(II).
There should be battery voltage.
• If there is no voltage, check for:
– Blown No. 36 (10 A) fuse in the under-dash
fuse/relay box.
– An open in the BRN wire.
• If there is battery voltage, go to step 5.
5. Check for continuity between terminal No. 6 and
body ground. There should be continuity.
• If there is no continuity, check for:
– An open in the BLK wire.
– Poor ground (G 503).
• If there is continuity, check both mirrors
individually as described in the next steps.
6. Connect terminals No. 2 and No. 10, and terminals
No. 5 (or No. 12) and No. 6 with jumper wires.
The left mirror should tilt down (or swing left) with
the ignition switch to ON (II).
• If the left mirror does not tilt down (or does not
swing left), check for an open in the PUR (or PNK)
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 GRN wire.
• If the mirror works properly, check the mirror
switch.
7. Connect terminals No. 2 and No. 11, and terminals
No. 5 (or No. 13) and No. 6 with jumper wires. The
right mirror should tilt down (or swing left) with the
ignition switch to ON (II).
• If the mirror does not tilt down (or does not swing
left), check for an open in the PUR (or BLU) 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 WHT wire.
• If the mirror works properly, check the mirror
switch.
8. Connect the power mirror defogger relay terminals
No. 1 and No. 2 in the under-hood fuse/relay box
with a jumper wire, and measure the voltage
between mirror connectors terminal No. 1 and
body ground. There should be battery voltage and
both mirrors should warm up with the ignition
switch to ON (II).
• If there is no voltage or neither warms up, check
for:
– An open in the ORN wire.
– Blown No. 36 (10 A) fuse in the under-dash
fuse/relay box.
• If only one fails to warm up, check:
– Its defogger.
– Poor ground (G 503).
• If both warm up, check the defogger switch.
