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.
23-96
5. If all the tests prove OK, replace the front accessory
socket.

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.

Rear Window Defogger
Function Test
1. Check for voltage between the positive terminal andbody ground with the ignition switch and defoggerswitch ON.
There should be battery voltage.
. lf there is no voltage. check for:- faulty defogger relay.- faulty defogger switch.- an open ,n the BLK/BLU, WHT/GRN, BLU/YEL,
or BLK wire.
. lf there is battery voltage, go to step 2.
POSITIVE TERMINAL
Check for continuity between the negative terminaland body ground.
lf there is no continuity, check for an open in thedefogger ground wire.
Touch the voltmeter positive probe to the halfwaypoint of each defogger wire, and the negative probe
to the negative terminal. Be careful not to scratch ordamage the defogger wires with the tester probe.There should be approximately 6 V with the ignitionswitch and the defogger switch ON.
. lf the voltage is as specified, the defogger wire isoK.
. lf the voltage is not as specified, repair the defog-ger wire.- lf it is more than 6 V, there is a break in thenegative half of the wire.- lf it is less than 6 V, there is a break in thepositive half of the wire.
23-112
Defogger Wire Repair
NOTE: To make an effective repair, the broken sectionmust be no longer than one inch.
1. Lightly rub the area around the broken section withfine steel wool, then clean it with alcohol.
2. Carefully mask above and below the broken portionof the defogger wire with cellophane tape.
CELLOPHANETAPE
Mix the conductive paint thoroughly. Using a smallbrush, apply a heavy coat of the conductive paint
extending about 1/8" on both sides of the break.Allow 30 minutes to dry.
Check for continuity in the repaired wire.
Apply a second coat of paint in the same way. Let itdry three hours before removing the tape.
