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.
