Wiper Pivot: Description and Operation
SYSTEM OPERATION
Wiper Linkage And Pivot
The wiper linkage and pivot module is secured with screws to the cowl top panel beneath the cowl plenum cover/grille panel. The wiper motor is
mounted on the engine compartment side of the cowl plenum panel. The wiper motor output shaft and crank arm are installed through a hole in the
cowl plenum panel into the cowl plenum area, where they connect to the wiper linkage.
The two wiper pivot crank arms and the wiper motor crank arm each have ball studs on their ends, the left pivot ball stud is the longer of the three.
A connecting link with a plastic socket-type bushing in the right end, and a plastic sleeve-type bushing in the left end, is fit over the pivot ball studs
to join the two pivots.
The wiper drive link has a plastic socket-type bushing on each end. One end of the drive link is fit over the exposed end of the longer left pivot
ball stud, while the other end is snap-fit over the ball stud on the wiper motor crank arm.
The wiper linkage, pivots, and bushings are only serviced as a complete unit. If any part of this assembly is faulty, the entire unit must be replaced.
The wiper motor and wiper motor crank arm are serviced separately.
