Both inoperative:
1. check for voltage between the No. 2 (BLVYEL) ter

There should be batterY voltage
. If there is no voltage, check for:
- blown No. 17 (7 5 A) fuse in the under-dash
tuse/relay box- an open in the BLK'/YEL wire.
o lf there is battery voltage, go to step 2.
2. Check for continuity between the No 4 (BLK) termi-
nal and body ground.
There should be continuity.
. lf there is no continuity, check for:
- an open in the BLK wire.
- poor ground (G551).
Left mirror inoporalive:
connect the No. 2 {BLK/YEL) terminal of the 10P connec-
tor to the No. 3 (YEURED) terminal and the No 5 (or No
6) terminal to body ground with jumper wires The left
mirror should tilt down (or swing left) when the ignition
switch is turned ON (ll)
. lf the mirror does not tilt down (or does not swing left),
remove the left door panel. and check for an open in
the BLU/WHT (or BLU/BLK) wire between the left
power mirror and the switch
- lf the wire is OK. check the left power mirror actua-
tor.
lf the mirror neither tilts down nor swings left. repair
the YEURED wire.
lf the mirror operates properly, check the mirror switch'
Right mirror inoperative:
Connect the No. 2 (BLK /EL) terminal of the 10P connector
to the No. 3 (YEURED) terminal and the No. 9 (or No 8)
terminal to body ground with jumper wires The right mir-
ror should tilt down (or swing left) when the ignition
switch is turned ON (ll).
. lf the mirror does not tilt down (or does not swlng
left), remove the right door panel. and check for an
open in the GRN/WHT (or YEUBLK) wire between the
right power mirror and the switch.
- lf the wire is OK, check the right power marror actu-
ator.
. lf the mirror neither tilts down nor swings left. repair
the YEURED wire
. lf the mirror operates properly, check the mirror
switch.
