1.
Disconnect the negative (-) battery terminal.
2.
Remove the windshield deicer relay from the engine
room relay box.
3.
There should be continuity between the No.30 and
No.87 terminal when power and ground are con-
nected to the No.85 terminal and No.86 terminal.
4.
There should be no continuity between the No.30
terminal and No.87 terminal when power is discon-
nected.

CAUTION
Wrap tin foil around the end of the voltmeter test
lead to prevent damaging the heater line. Apply
finger pressure on the tin foil, moving the tin foil
along the grid line to check for open circuits.

1.
Turn on the defogger switch and use a voltmeter to
measure the voltage of each heater line at the glass
center point. If a voltage of approximately 6V is in-
dicated by the voltmeter, the heater line of the rear
window is considered satisfactory.

If a heater line is burned out between the center point
and (+) terminal, the voltmeter will indicate 12V.

4.
To check for open circuits, slowly move the test lead
in the direction that the open circuit seems to ex-
ist. Try to find a point where a voltage is generated
or changes to 0V. The point where the voltage has
changed is the open-circuit point.
Voltage changes before and
after open circuited point
Here is 0V voltage

5.
Use an ohmmeter to measure the resistance of each
heater line between a terminal and the center of a grid
line, and between the same terminal and the center of
one adjacent heater line. The section with a broken
heater line will have a resistance twice as that in other
sections. In the affected section, move the test lead
to a position where the resistance sharply changes.

REPAIR OF BROKEN HEATER LINE
Prepare the following items :
1.
Conductive paint.
2.
Paint thinner.
3.
Masking tape.
4.
Silicone remover.
5.
Using a thin brush :
Wipe the glass adjacent to the broken heater line,
clean with silicone remover and attach the masking
tape as shown. Shake the conductive paint container
well, and apply three coats with a brush at intervals of
about 15 minutes apart. Remove the tape and allow
sufficient time for drying before applying power. For a
better finish, scrape away excess deposits with a knife
after the paint has completely dried. (Allow 24 hours).
