INSPECTION OF REAR DEFOGGER HEAT
WIRE
• Heat wires are printed on the inner side of glass.
To clean, use a soft cloth and wipe horizontally along the
wires.
• Never use glass cleaner or equivalent.
• When measuring voltage, wind a piece of tin foil around the
tip of the negative probe and press the foil against the wire
with your finger as shown.
(1) Turn the ignition switch on.
(2) Turn the defogger switch on.
(3) Measure the voltage between the three points on the heat
wire and the (-) terminal with a voltmeter.
(4) Check that the voltage becomes smaller from
A
to
B
to
C
.

(5) If there is a place where the voltage suddenly changes to
0V, there is a broken wire between there and the power
side.
(6) Move the tester probe from the position where the voltage
changes to 0V toward the power side and find where the
voltage suddenly increases.
REPAIR OF BROKEN HEAT WIRE
(1) Clean broken wire tips with white gasoline.
(2) Place masking tape along both sides of wire to be repaired.
(3) Thoroughly mix the repair agent (Dupont paste No. 4817 or
equivalent).
(4) Using a fine tip brush, apply a small amount to the wire.
(5) After a couple of minutes, remove the masking tape.
(6) Allow to stand at least 24 hours.
