DIAGNOSIS
TESTING REAR WINDOW
DEFOGGER GRID LINE
If it has been observed during use that a grid line is inop-
erative, the following procedure can be used to find the
break. If none of the grid lines is operating, a full system
diagnosis should be completed before attempting to repair
the grid lines.
1. Turn the ignition ON.
2. Turn the rear window defogger on.
3. From the inside of the vehicle, connect a voltmeter
to each end of a grid line. The voltmeter will indi-
cate battery voltage if the grid line is open.
Notice : Use care when touching the voltmeter leads to a
grid line. If the leads are roughly applied, the grid line may
be scratched, resulting in an open circuit.4. If a grid line is found to be open, move a voltmeter
lead from one side of the grid line and retest at a
point nearer to the other side of the window. Contin-
ue to retest, each time bringing one of the voltmeter
leads closer to the opposite side of the window
from where it was originally placed. The break in
the grid line is at the point where the voltmeter be-
gins reading 0 volts instead of battery voltage.
5. Use a marking crayon to lightly mark the break
point on the rear window. Mark the glass instead of
marking directly on the grid line, and make the
mark far enough from the grid line so that it can
easily be removed without disturbing the repair.
6. Use a grid line repair kit to fix the break in the grid
line. Refer to ”Rear Window Defogger Grid Line
Repair” in this section.
