WIPER MODULE
DESCRIPTION
The wiper module is secured with screws through four rubber grommet-type insulators (1) to the cowl plenum panel.
The module is concealed beneath the molded plastic cowl plenum cover/grille panel between the base of the wind-
shield and the rear edge of the hood panel. The ends of the pivot shafts protruding through openings in the cowl
plenum cover/grille panel to drive the wiper arms and blades are the only visible components of the wiper module.
The wiper module consists of the following major components:
•
Bracket - The wiper module bracket (2) consists of a long tubular steel main member that has a die cast pivot
bracket at each end to which the two wiper pivots (4) are secured. A stamped steel motor bracket is welded
near the center of the tubular member to which the wiper motor (5) is secured.
•
Crank Arm (7) - The wiper motor crank arm is a stamped steel unit with a slotted hole on the driven end that
is secured to the wiper motor output shaft with a nut, and has a ball stud secured to the drive end.
•
Linkage (3) - Two stamped steel drive links connect the wiper motor crank arm to the wiper pivot lever arms.
The right side drive link has a plastic socket-type bushing on each end. The left 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 lever arm of its respective pivot. The left 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 right side drive link is snap-fit over the exposed end of the wiper motor crank arm ball stud.
•
Motor (5) - The wiper motor features a transmission housing from which the wiper motor output shaft exits and
three threaded holes that mount the motor to the module bracket with three screws. A nut secures the wiper
motor crank arm to the motor output shaft. The two-speed permanent magnet wiper motor features an integral
transmission, an internal park switch, and an internal automatic resetting circuit breaker. A short pigtail wire
and connector (6) connect the wiper motor to the vehicle electrical system through a dedicated take out and
connector of the headlamp and dash wire harness.
•
Pivots (4) - The two wiper pivots are secured within the die cast pivot brackets on the outboard ends of the
wiper module main member. The lever arms that extend from the center of the pivot shafts each have a ball
stud on their end. The upper end of each pivot shaft where the wiper arms will be fastened each has a ser-
rated driver with a threaded stud. The lower ends of the pivot shafts are installed through lubricated bushings
in the pivot brackets and are secured with snap rings.
The wiper module cannot be adjusted or repaired. If any component of the module is faulty or damaged, the entire
wiper module unit must be replaced.
