Rear Window Wiper Washer

WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.

The generic electronic module (GEM) allows operation of the rear window wiper functions when the ignition switch is in the RUN or ACC position only. The GEM controls the cycling of the rear window wiper motor through a single relay (rear window wiper relay).

There are four modes of operation: off mode, interval mode, on mode and wash mode.

NOTE:

The GEM does not control the rear window washer, only the rear window wiper.

In the off mode, there is no liftgate wiper motor activity and the liftgate wiper motor will be in the PARK position. When the wiper/washer switch is placed in the interval position, the GEM will activate the rear window wipe cycle of the rear window wiper motor. Once the wiper cycle has reached the LO position, after the initial wipe, the GEM will start a cyclical timing function.

In the ON mode, the GEM will cycle the rear window motor continuously at a set-speed setting. The GEM provides a ground to activate the rear window wiper relay. The wash mode can only be activated when the rear wiper switch is in the OFF or ON positions. When the rear wiper switch is in the OFF position and wash mode is activated, the rear window wiper will not cycle.

Fluid for the rear window washer is supplied by a washer pump located in the rear passenger compartment.
