Liftgate Window Glass: Testing and Inspection
INSPECT BACK DOOR GLASS (DEFOGGER WIRE)
NOTE:
-
When cleaning the glass, wipe the glass along the wire using a soft and dry cloth. Take care not to damage 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 tester probe and press the foil against the wire with your finger, as
shown in the illustration.
a. Turn the ignition switch ON.
b. Turn the defogger switch ON.
c. Check the voltage at the center of each defogger wire, as shown in the illustration.
HINT: If there is approximately 10 V, the wire may be faulty between the center of the wire and the wire end on the battery side. If there is no
voltage, the wire may be faulty between the center of the wire and the wire 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 voltage jumps from approximately 10 V to 0 V is where the defogger wire is broken.
