NOTE:

1. Measure voltage between the positive terminal (A) and body ground with the ignition switch and the defogger switch ON.

There should be battery voltage.

2. Turn the ignition switch OFF, and disconnect the negative terminal (B) from the rear window defogger.

3. Check for continuity between the negative terminal (B) and body ground.

If there is no continuity, check for an open in the wire or poor ground (G602). If there is continuity, go to step 4.

4. Reconnect the negative terminal to the rear window defogger.

5. Turn the ignition switch ON (II) and the rear window defogger switch ON.

6. Touch the voltmeter positive probe to each point on each defogger wire, and the negative probe to the negative terminal.

Defogger Wire Repair

NOTE: To make an effective repair, the broken section must be no longer than 1 in. (25 mm).

1. Lightly rub the area around the broken section (A) with fine steel wool, then clean it with alcohol.

2. Carefully mask above and below the broken portion of the defogger wire (B) with cellophane tape (C).

3. Using a small brush, apply a heavy coat of silver conductive paint (commercially available) (A) extending about 1/8" on both sides of the break.

Allow 25 minutes to dry.
