WIPER MODULE
DESCRIPTION
The front wiper module is secured to stamped brackets within the cowl plenum panel beneath the cowl plenum
cover/grille panel. The ends of the wiper pivot shafts protrude through dedicated openings in the cowl plenum cover/
grille panel to drive the wiper arms and blades and are the only visible components of the front wiper module.
The front wiper module consists of the following major components:
•
Bracket - The front wiper module bracket (4) consists of a long tubular steel main member that has a stamped
pivot bracket formation near each end where the two wiper pivots are secured. The front wiper module bracket
is secured within the cowl plenum by two screws through two rubber insulators (6).
•
Crank Arm - The front wiper motor crank arm (5) 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 a ball stud secured to the drive end.
•
Linkage - Two stamped steel drive links (7) connect the wiper motor crank arm to the two wiper pivot lever
arms. The passenger side link has a plastic socket-type bushing on each end, while the driver side link has a
socket-type bushing on the pivot end and a sleeve-type bushing on the crank arm end. The bushing on the
pivot end of each link is snap-fit over a ball stud on the pivot lever arm. The sleeve-type bushing on the driver
side link is snap fit over the inner ball formation of a double ball stud on the crank arm, then the socket-type
bushing of the passenger side drive link is snapped over the outer ball formation.
•
Motor - The front wiper motor (9) is secured by a bracket (3) integral to the motor transmission housing with
two screws and nuts near the center of the wiper module bracket. A knob-like rubber insulator (8) on a stud
integral to the motor transmission housing is engaged in a slot in a stamped bracket on the forward wall of the
cowl plenum. The two-speed permanent magnet wiper motor features an integral transmission, an internal park
switch, and an internal automatic resetting circuit breaker.
•
Pivots - The two front wiper pivots (1) are secured to the ends of the wiper module bracket. The lever arms
that extend from the bottom of the pivot shafts. A molded plastic shield (2) is fit over the top of each pivot
housing. The upper end of each pivot shaft where the wiper arms will be fastened each is tapered and ser-
rated with a threaded stud formation at the tip.
