Wiper Pivot: Description and Operation
SYSTEM OPERATION
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
secured with screws 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 are connected to the wiper linkage.
The two wiper pivot crank arms and the wiper motor crank arm each have ball studs on their ends. The ball stud on the driver side pivot crank arm
is longer than the other two ball studs. A connecting link with a plastic socket-type bushing in the passenger side end, and a plastic sleeve-type
bushing in the driver side end, is fit over the pivot crank arm 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 snap-fit over the exposed end of the longer driver
side 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 wiper linkage unit
must be replaced. The wiper motor is serviced separately.
