Wiper/Washer Systems: Description

Jeep vehicles use a two-speed electric motor which is a compound wound (series and shunt) type. A crank arm is attached externally to gear shaft and operates linkage which activates the wiper blades. All models except "CJ" and Scrambler have an optional intermittent feature. All models use an electric washer system which consists of a motor, reservoir and necessary hoses and nozzles. The pump assembly is mounted in the bottom of the reservoir. The motor case is grounded to the vehicle body and is energized by a feed wire from the control switch.
