Rear Wiper and Washer System

NOTE: The GEM will not activate the rear wiper system if either the liftgate or the liftgate glass is ajar. If either the liftgate or the liftgate glass becomes ajar while the rear wiper is in operation, the GEM will park the rear wiper motor.

There are two distinct modes of wiper operation:
^ Off Mode: In this mode, there is no rear wiper activity, and the wiper motor will be in the PARK position.
^ Interval Mode: This mode is selected when the rear wiper switch is in either the interval 1 or 2 positions. When this mode is selected, the rear wiper motor is driven up onto the glass by activating the rear wiper UP relay. When the wiper motor HIGH/LOW/PARK position input reaches the high position, the UP relay is deactivated and the DOWN relay is activated to reverse the wiper motor direction. When the wiper motor reaches the LOW position, as determined by the HIGH/LOW/PARK position input, the GEM deactivates the DOWN relay and will begin a new wiper cycle 1 to 10 seconds later, depending on the interval position selected.

Rear Window Washer System
To engage the rear window washer, rotate the rear window washer selector downward to the WASH position. The rear window wiper will run as long as WASH position is selected. When the rear window washer selector returns to the OFF, INT 1, or INT 2 position, the washer will stop immediately, but the rear window wiper will continue for two to three sweeps then return to its previous mode of operation.
