REAR DEFOGGER RELAY
Check continuity between the relay terminals.

(When battery voltage is applied between
4 and 3)
2- 1......................... Continuity


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 hea
t
wire and the (-) terminal with a voltmeter.
(4) Check that the voltage becomes smaller from
A to B to C.
