NOTE: Check the No. 4 (15A) fuse in the under-dash

fuse box before testing.

One or both inoperative:

1. Check for voltage between the YEL/BLK1 terminal

and body ground with the ignition switch ON (II).

There should be battery voltage.

• If there is no voltage, check for an open in the

YEL/BLK1 wire.

• If there is battery voltage, go to step 2.
2. Check for continuity between the BLK terminal and

body ground.

There should be continuity. If there is no continui-

ty, check for:

• An open in the BLK wire.

• Poor ground (G401, G402, G403).

Left inoperative:

Connect the YEL/BLK1 terminal to the YEL/RED terminal

and the YEL/WHT (or YEL/BLK2) terminal to body

ground with jumper wires.

The
left mirror should
tilt
down
(or
swing left) when
the

ignition switch is turned ON (II).

• If the
mirror
does
not
tilt
down
(or
does
not
swing

left), check for an open in the YEL/WHT (or

YEL/BLK2) wire between the left door mirror and the

switch.

If the wire is OK, check the mirror.

• If the mirror doesn't move either direction, repair the

YEL/RED wire.

• If the mirror operates properly, check the mirror

switch.

Right inoperative:

Connect the YEL/BLK1 terminal to the BLU/GRN ter-

minal and the YEL/WHT (or BLU/BLK) terminal to the

body ground with jumper wires.

The right mirror should tilt down (or swing left) when

the ignition switch is turned ON (II).

• If the
mirror does
not
tilt
down
(or
does
not
swing

left), remove the right door panel, and check for an

open in the YEL/WHT or BLU/BLK) wire between the

right door mirror and the switch.

If the wire is OK, check the right door mirror.

• If the mirror doesn't move in either direction, repair

the BLU/GRN wire.

• If the mirror operates properly, check the mirror
