System Description=NJEL0463The rear window defogger system is controlled by the time control unit. The rear window defogger operates
only for approximately 15 minutes.
Power is supplied at all times
+through 20A fuse [No. 7, located in the fuse block (J/B)]
+to rear window defogger relay terminal 5 (B7 relay models) or 3 (B6 relay models)
+through 10A fuse [No. 13, located in the fuse block (J/B)]
+to rear window defogger relay terminal 6 (B6 relay models).
+through 15A fuse [No. 5, located in the fuse block (J/B)]
+to time control unit terminal 9.
With the ignition switch in the ON or START position, power is supplied
+through 10A fuse [No. 10, located in the fuse block (J/B)]
+to the rear window defogger relay terminal 1 and
+to time control unit terminal 1.
Ground is supplied to terminal 5 of the rear window defogger switch through body grounds M28 and M67.
When the rear defogger switch is turned ON, ground is supplied
+through terminal 3 of the rear defogger switch
+to time control unit terminal 3.
Terminal 13 of time control unit then supplies ground to the rear window defogger relay terminal 2.
With power and ground supplied, the rear window defogger relay is energized.
Power is supplied
+through terminals 5 and 7 of the rear window defogger relay (B6 relay models) or
+through terminal 3 of the rear window defogger relay (B7 relay models)
+to the rear window defogger and door mirror defogger.
The rear window defogger has an independent ground.
With power and ground supplied, the rear window defogger filaments heat and defog the rear window.
When the system is activated, the rear window defogger indicator illuminates in the rear window defogger
switch.

+When measuring voltage, wrap tin foil around the top of
the negative probe. Then press the foil against the wire
with your finger.

REPAIRING PROCEDURENJEL0078S021. Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.
2. Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit conductive sil-
ver composition on break with drawing pen. Slightly overlap
existing heat wire on both sides [preferably 5 mm (0.20 in)] of
the break.
SEL012D
4. After repair has been completed, check repaired wire for con-
tinuity. This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
SEL013D
5. Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area
and hot air outlet. If a heat gun is not available, let the repaired
area dry for 24 hours.
