Front washer pump
The front washer pump consists of a DC motor with an impeller. It is located in the rear of the washer fluid reservoir
and can be identified by its black top.
Operating the front washer switch provides battery voltage to the front washer pump. This same battery voltage signal
also goes to the BCU and increments the headlamp powerwash counter providing the headlamps are switched on.
Rear washer pump
The rear washer pump consists of a DC motor with an impeller. It is located in the rear of the washer fluid reservoir
and can be identified by its red top.
Operating the rear washer switch provides battery voltage to the rear washer pump.

DESCRIPTION AND OPERATION 84-15
Headlamp powerwash pump
The headlamp power wash pump consists of a DC motor with an impeller. It is located on the front of the washer fluid
reservoir.
The BCU controls operation of the headlamp power wash relay, which supplies battery voltage from fuse 4 located in
the engine compartment fuse box to the headlamp power wash pump. When the BCU determines headlamp power
wash is to be activated, it provides a ground path for the coil of the headlamp power wash relay. The auxiliary relay
located in the engine compartment fuse box supplies the headlamp power wash relay coil with battery voltage.
