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.
