RAM 1500 Van V8-5.2L CNG VIN T (1999)
Wiper Motor: Description and Operation
SYSTEM OPERATION
The two-speed permanent magnet wiper motor has an integral transmission and park switch. The motor has a rubber-isolated mounting bracket
that is secured with screws to a reinforcement with weld nuts on the engine side of the cowl plenum panel. The wiper motor output shaft and crank
arm passes through a hole in the cowl plenum panel into the cowl plenum area.
Wiper speed is controlled by current flow to the proper set of brushes. The wiper motor completes its wipe cycle when the windshield wiper switch
on the end of the multi-function switch stalk is turned to the Off position, and parks the blades in the lowest portion of the wipe pattern.
The windshield wiper motor cannot be repaired. If faulty or damaged, the entire wiper motor assembly must be replaced. The wiper linkage and
pivots, and the reinforcement are available for service.
