STANDARD PROCEDURE
GRID LINE AND TERMINAL REPAIR
REAR WINDOW DEFOGGER GRID LINES
grid lines fired on the inside surface. A control switch
and a timing circuit are combined into a single
assembly.
A push-button at the center of the instrument
panel, below the radio, turns the defroster ON or
OFF.
Circuit protection is provided by a cartridge fuse
located in the Power Distribution Center (PDC) for
the heated grid circuit, and by a fuse in the fuse
block for the control circuit.
OPERATION
When the switch is turned to the ON position, cur-
rent is directed to the rear defogger grid lines. The
heated grid lines heat the rear glass to clear the sur-
face of fog or frost. An amber light shows that the
defroster is on.
NOTE: The defroster turns off automatically after 10
minutes of operation. Each following activation of
the defroster will last for five minutes.
CAUTION: Grid lines can be damaged or scraped
off with sharp instruments. Care should be taken in
cleaning glass or removing foreign materials,
decals or stickers. Normal glass cleaning solvents
or hot water used with rags or toweling is recom-
mended.
DIAGNOSIS AND TESTING

Electrically heated rear window defogger operation
can be checked in the vehicle in the following man-
ner:
