Rear Window Defogger
Function Test
NOTE:. Be careful not to scratch or damage the defogger
wires with the tester probe.
. Before testing, check the No. 11 (30A) fuse in the
under-hood fuse/relay box and No. '14 ('10A) fuse in
the under-dash fuse/relay box.
1. Check for voltage between the ve rtica I dividersand
body ground with the ignition switch and defogger
switch ON.
There should be voltage as shown.
. lf there is no voltage. checkfor:- faulty defogger relay.- an open in the BLK, BLK,/YEL, or YEL/BLK wire.- taulty heater control panel.
. lf there is battery voltage, goto step 2.
6V
Check for continuity between the negative terminal(B) and body ground.
lf there is no continuity, check for:. an open in the BLK wire.. Poor body ground at the window antenna coil
mounting bolt.
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.
. lf thevoltage is asspecified, the defoggerwlre is
oK.. lf the voltage is not as specified, repair the
defogger wire.- lf it is more than 6 V, there is a break in the
negative half of the wire.- lf 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 one inch.
1. Lightly rub the area around the broken section (A)
with fine steel wool, then clean it with alcohol.
Carefully mask above and below the broken portion
of the defogger wire (B) with transparent tape {C).
Mix the silver conductive paint thoroughly. Using a
small brush, apply a heavy coat of paint extending
about 1/8 inch 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 it
dry 3 hours before removing the tape.

Noise Gondenser Capacity Test
1.Remove the right rear side trim panel (see page 20-
66).
Disconnect the 2P connector (A) from the noise
condenser.
Noise condenser capacity:
0.47 a 0.09 microfarads
Wire side ol female terminals
4.
Use a commercially available condenser tester.
Connect the condenser tester probes, and the
measure condenser capacity.
lf it is not within the specification, replace the noise
condenser.
