Rear Window Defogger

Function Test

CAUTION: Be careful not to scratch or damage the

defogger wires with the tester probe.

Check for voltage between the positive terminal

and body ground with the ignition switch and the

defogger switch ON. There should be battery

voltage.

If there is no voltage, check for:

— Faulty defogger relay.

— An open in the BLK/GRN wire.

If there is battery voltage, go to step 2.

POSITIVE TERMINAL

NEGATIVE TERMINAL

2. Disconnect the positive terminal, check for con-

tinuity between the negative terminal and body

ground. If there is no continuity, check for an open

in the defogger ground wire.

3. Reconnect the positive terminal, touch the

voltmeter positive lead to the middle of each defog-

ger wire, and the negative lead to the negative ter-

minal. There should be approximately 6 V with the

ignition switch and the defogger switch ON.

If the voltage is as specified, the defogger wire

is OK.

If there is battery voltage, the defogger wire is

broken on the negative side.

If there is no voltage, the defogger wire is

broken on the positive side.
Defogger Wires Repair

To make an effective repair, the broken section must be

no longer than one inch.

1. Lightly scrub the area around the break with fine

steel wool, then clean it with alcohol.

2. Carefully mask above and below the broken section

with cellophane tape.

OPEN

CELLOPHANE

DEFOGGER WIRE

3. Using a small brush, apply a heavy coat of silver

conductive paint extending about 1/8" on both

sides of the break. Thoroughly mix the paint before

use. Let it dry for thirty minutes.

PAINT

4. Check for proper operation with a voltmeter (it

should read half of battery voltage at the mid-

point).

5. Apply a second coat of paint in the same way. Let it

dry for three hours before removing the tape.ProCarManuals.com
