Grand Cherokee 2WD V8-5.2L VIN Y (1998)
Wiper Motor Linkage: Description and Operation
SYSTEM OPERATION
The wiper linkage and pivot module is secured with screws to the cowl plenum 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 motor crank arm ball stud is the longer of
the three. Two drive links connect the motor crank arm to the pivot crank arms.
The passenger side drive link has a plastic socket-type bushing on each end. The driver side drive link has a plastic socket-type bushing on one
end, and a plastic sleeve-type bushing on the other end.
The socket-type bushing on one end of each drive link is snap-fit over the ball stud on the crank arm of its respective pivot. The driver side drive
link sleeve- type bushing end is then fit over the motor crank arm ball stud, and the other socket-type bushing of the passenger side drive link is
snap-fit over the exposed end of the motor crank arm ball stud.
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 wiper linkage and pivots module must be replaced. The wiper motor is serviced separately.
