Wiper Motor Linkage: 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 to the center of the linkage and pivot module bracket. The wiper pivots are secured to the ends of the module bracket.
The two wiper pivot crank arms and the wiper motor crank arm each have ball studs on their ends. The left pivot ball studs 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 snap-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, bushings, motor, crank arm, and mounting bracket are only serviced as a complete unit. If any part of this assembly is
faulty or damaged, the entire unit must be replaced.
