Rear Window Defogger
Control Unit Input Test (cont'd)
NOTE: Before testing, go to the Troubleshooting Guide (see page
). Be sure to go through self-diagnosis function
and
).
Multiplex Control Unit (Driver's):
1. Remove the under-dash fuse/relay box (see page
).
2. Remove the driver's unit from the under-dash fuse/relay box (see page
).
3. Inspect the connector and socket terminals to be sure they are all making good contact.
• If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
• If the terminals look OK, make the following input tests at the connector and the fuse/relay box socket.
If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the control unit must be faulty; replace it.

Rear Window Defogger
Function Test
CAUTION: Be careful not to scratch or damage the defog-
ger wires with the tester probe.
1. Check for voltage between the positive terminal and
body ground with the ignition switch and defogger
switch ON.
There should be battery voltage.
• If there is no voltage, check for:
faulty defogger relay,
faulty defogger switch.
faulty defogger coil.
an open in the YEL/BLU wire.
• If there is battery voltage, go to step 2.
NEGATIVE TERMINAL
POSITIVE TERMINAL
2. Check for continuity between the negative terminal
and body ground.
If there is no continuity, check for an open in the
defogger ground wire.
3. Touch the voltmeter positive probe to the halfway
point of each defogger wire, and the negative probe
to the negative terminal.
There should be about 6 V with the ignition switch
and the defogger switch ON.
If the voltage is as specified, the defogger wire is
OK.
If the voltage is not as specified, repair the
defogger wire.
If it is more than 6 V, there is a break in the
negative half of the wire.
If it is less than 6 V, there is a break in the
positive half of the wire.
Defogger Wire Repair
NOTE: To make an effective repair, the broken section
must be no longer than 1 inch.
1. Lightly rub the area around the broken section with
fine steel wool, then clean it with alcohol.
2. Carefully mask above and below the broken portion
of the defogger wire with cellophane tape.
3. Using a small brush, apply a heavy coat of silver
conductive paint extending about 1/8" on both
sides of the break. Allow 30 minutes to dry.
BROKEN WIRE
CELLOPHANE
TAPE
NOTE: Thoroughly mix the paint before use.
4. Check for continuity in the repaired wire.
5. Apply a second coat of paint in the same way. Let it
dry 3 hours before removing the tape.
