Disconnect the connectors from the daytime run-
ning lights control unit.
Inspect the connector and socket terminals to be
sure they are all making good contact.
lf the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.

Accessory Socket
Accessory Socket Test/Replacement
Front Accessory Socket:
1. Remove the center dashboard lower cover (see sec-
tion 20).
Disconnect the 2P connector from the front accessory
socket.
Inspect the connector terminals to be sure they are
all making good contact.
2.
lf the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
lf the terminals look OK, go to step 4.
ACCESSORYSOCKET
Turn the ignition switch to ACC (l), and check for
voltage between the No. 1 and No. 2 terminals.
. There should be battery voltage.
. lf there is no battery voltage, check for:- blown No.27 (10 A) fuse in the under-dash
fuse/relay box.- poor ground (G401, G402).- an open in the wire.

Power Mirrors
Function Test
1.Pry the switch out of the dashboard. Be careful notto damage the mirror switch or the dashboard driv-er's lower cover when prying the switch out.Disconnect the 10P connector from the switch.Choose the appropriate test dased 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.
Both inoperative:
4. Check for voltage between the No. 2 (BLVYEL) ter-minal and body ground with the ignition switch ON
fl r).
There should be baftery voltage,. lf there is no voltage, check for:- blown No. 17 (7.5 A) fuse in the under-dashfuse/relay box.- an open in the BLK,/YEL wire.. lf there is battery voltage, go to step 2.5. 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 (c551).

Left mirror inoperative:
6. Connect the No. 2 {BLKI/EL) terminal of the ,l0p
connector to the No. 3 (YEUREDI terminal and theNo.5 (or No.6) terminal to body ground withjumper wires. The left mirror should tilt down (or
swing left) when the ignition switch is turned ON t).
lf the mirror doei not tilt down (or does not swingleft), remove the left door panel, and check for anopen in the BLUMHT (or BLU/BLK) wire betweenthe left power mirror and the switch. lf the wire isOK, check the left power mirror actuator,
lf the mirror neither tilts down nor swings left,repair the YEURED wire.
lf the mirror operates properly, check the mirrorswitch.
Right mirror inoperaiiva:
7. Connect the No. 2 {BLVYEL) terminat of the 1Op con-nector to the No. 3 (YEURED) terminal and the No. 9(or No. 8) terminal to body ground with jumper wires.The right mirror should tilt down (or swing left) whenthe ignition switch is turned ON l).
. lf the mirror does not tilt down (or does notswing left), remove the right door panel, andcheck for an open in the GRN,4TVHT (or yEUBLK)
wire between the right power mirror and theswitch. lf the wire is OK, check the right power
mtrror actuator.
. lf the mirror neither tilts down nor swings left.repair the YEURED wire.. lf the mirror operates properly, check the mirrorswitch.
