Inspection
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 indicated by the voltmeter, the heater line of
the rear window is considered satisfactory.
|
2. |
If a heater line is burned out between the center point and (+)
terminal, the voltmeter will indicate 12V.
|
3. |
If a heater line is burned out between the center point and (-)
terminal, the voltmeter will indicate 0V.
|
4. |
To check for open circuits, slowly move the test lead in the direction
that the open circuit seems to exist. 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.
|
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.
|
6. |
If the heat line fails, replace the rear glass.
