FILAMENT
Inspection
1. Turn the ignition switch to ON.
2. Press the rear window defroster switch.
3. Connect the (+) terminal of a voltmeter to the center of
each filament and the (-) terminal to the body. The
standard voltage at the center of each filam ent is
approximately
6V. If the meter indication is low or zero,
there is a short circuit between the center and the
ground side of the filament. If the indication is high, the
malfunction is between the center and positive side.
Repair
Caution
• Use only paint thinner or ethyl alcohol for clean­
ing. Other solvents can damage the surrounding
filament.
1. Use paint thinner or ethyl alcohol to clean around the
damaged section of the filament.
2. Attach tape above and below the damaged section of
the filament.
3. Using a small brush or marking pen, repair the filament
with silver paint or equivalent.
4. Use a blow dryer heated to 150°C {302°F} for 30 min­
utes or let the paint set for 24 hours at 25°C {77°F} to
allow it to dry completely. Do not use the defroster until
the paint is dry.
