3. INSPECT DEFOGGER WIRES
NOTICE:
When cleaning the glass, use a soft, dry cloth and wipe the
glass in the direction of the wire. Take care not to damage
the wires.Do not use detergents or glass cleaners with
abrasive ingredients.When measuring voltage, wind a
piece of tin foil around the top of the negative ( −) probe and
press the foil against the wire with your finger, as shown.
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
(c) Inspect the voltage at the center of each heat wire, as shown.
VoltageCriteria
Approx. 5VOkay (No break in wire)
Approx.10V or 0VBroken wire
HINT:
If there is 10 V, the wire is broken between the center of the wire
and positive (+) end. If there is no voltage, the wire is broken
between the center of the wire and ground.
(d) Place the voltmeter positive (+) lead against the defogger
positive (+) terminal.
(e) Place the voltmeter negative ( −) lead with the foil strip
against the heat wire at the positive (+) terminal end and
slide it toward the negative ( −) terminal end.
