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.

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.
