VEHICLE APPLICATION Taurus/Sable.
DESCRIPTION AND OPERATION
The heated rear window defroster system consists of a switch and relay control assembly mounted to the instrument panel and a series of grid wires
baked on the inside surface of the rear window. When the control switch is activated by the rocker or push button, current is directed to the grid wires on
the rear window. The heated grid wires keep the rear window clear of fog or ice.
The integral timer automatically turns off tile heating grid after approximately 10 minutes of operation. If more than 10 minutes of use is needed, the grid
can be reactivated for another 10 minutes by pushing the rocker or push button to the ON position. This operation can be repeated as required. Power for
the control timer and relay coil comes from the RUN terminal of the ignition switch and from a wire containing a fuse link connected to the starter relay.
