Rear Window Defogger
Function TestDefogger Wires Repair
I
I
CAUTION: Be caretul not to scratch or damage the
defogger wires with the tester probe,
1. Check tor voltage between the positive terminal and
body ground with the ignition switch and the defog-
ger switch ON. There should be battery voltage.
lf there is no voltage, check for
faulty defogger relay.- faulty defogger switch.- faulty integrated control unit.- an open in the BLK/GRN wire.
lf there is battery voltage, go to step 2.
NEGATIVE TERMINALPOSITIVE TEFMINAL
2.Turn the rear window defogger switch OFF. Check
for continuity between the negative terminal and
body ground.
a lf there is no continuity, check for an open in the
defogger ground wire.a lf there is continuity, go to step 3.
Touch the voltmeter positive lead to the halfwaypoint of each delogger wire, and the negative lead
to the negative terminal.
There should be approximately 6 V with the ignition
switch and defogger switch ON,
a lf the voltage is as specified, the defogger wire
is OK.
a lf the voltage is not as specified, repair the defog-ger wire:
lf it is more than 6 V, look for the damage on
the negative half on the grid.
lf it is less than 6 V, look for the damage onthe positive half of rhe grid.
3.
NOTE: To make an elfective repair, the broken section
must be no longer than one inch.
1 . Lightly rub the area around the break 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.
CELLOPHANETAPE
BBOKEN WIRE
3, Using a small brush, apply a heavy coat of silver con-
ductive paint extending about 3 mm (l /8 in) on both
sides of the break. Allow 30 minutes to dry.
NOTE: Thoroughly mix the paint before use.
Check for continuity in the repaired wire.
Apply a second coat of paint in the same way.
it dry three hours before removing the tape.
