7. INSPECT BACK WINDOW (DEFOGGER WIRE)
NOTICE:

When cleaning the glass, wipe the glass along the
wire using a soft and dry cloth. Take care not to dam-
age the wires.

Do not use detergents or glass cleaners including
abrasive ingredients.

When measuring voltage, wrap a piece of tin foil
around the tip of the negative probe and press the foil
against the wire with your finger, as shown in the il-
lustration
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
(c) Inspect the voltage at the center of each defogger wire,
as shown in the illustration.
Standard:
VoltageCriteria
Approx. 5 VOkay, wire is not broken
Approx. 10 or 0 VWire is broken
HINT:
If there is approximately 10 V, the wire may be broken between
the center of the wire and the end on the battery side. If there
is no voltage, the wire may be broken between the center of the
wire and the end on the ground side.
(d) Place the voltmeter positive (+) lead against the defogger
wire on the battery side.
(e) Place the voltmeter negative (±) lead with the foil strip
against the wire on the ground side.
(f) Slide the positive (+) lead from the battery side to the
ground side.
(g) The point where the voltmeter deflects from approx. 10V
to 0 V is the place where the defogger wire is broken.
HINT:
If the defogger wire is not broken, the voltmeter indicates 0 V
at the positive (+) end of the defogger wire but gradually in-
creases to about 12 V as the meter probe moves to the other
end.

4817).
(4) Using a fine tip brush, apply a small amount of the
agent to the wire.
(5) After a few minutes, remove the masking tape.
NOTICE:
Do not repair the defogger wire again for at least 24 hours.
