Defroster Filament
1. Turn the rear window defroster switch ON.
2. Connect the + terminal of the voltmeter to the cen-
ter of each filament and the - terminal to the
body. The standard voltage at the center of each
filament is approximately 6V. If the meter indica-
tion is high, there is a short circuit between the cen-
ter and the grounded side of the filament.
If the indication is low or zero, the fault is between
the center and positive side.
Repairing Filament
1. Use paint thinner or ethyl alcohol to clean the
damaged part of the filament.
2. Attach tape to both sides of the damaged part of
the filament.
3. Using a small brush or marking pen, apply silver
paint (part no 2835 77 600) or equivalent to the
damaged part.
4. Let the paint set for 24 hours at 20°C (68°F) to
let it dry completely. (If a blow dryer is used to heat
it to 60°C (140°F), it can be dried in about 30
minutes.)
Note
a) Do not use the rear-window defroster until
the paint is dry.
b) Do not use gasoline or similar solvents to
clean the damaged part.
