Wiper Motor Linkage: Description and Operation
Wiper Arm Linkage - Description
DESCRIPTION
The wiper module is secured to the cowl plenum with screws through two rubber grommet-type insulators. The module is located in the rear of the
engine compartment, concealed beneath the molded plastic cowl plenum grille panel. The ends of the pivot shafts protruding through openings in the
cowl plenum cover/grille panel are the only visible components of the wiper module. The wiper module consists of the following major components:
-
Crank Arm - The wiper motor crank arm is a stamped steel unit with an internally splined hole on the driven end that is secured to the wiper
motor output shaft with a nut.A long ball stud secures the drive end to accept the wiper linkage.
-
Linkage - The two wiper linkage members are constructed of stamped steel. A driver side drive link consists of a plastic socket-type bushing in
the left end, and a plastic sleeve-type bushing in the right end. The socket bushing is snap-fit over the pivot ball stud on the left pivot lever arm,
while the sleeve bushing is fit over the longer pivot stud on the wiper motor crank arm. The passenger side drive link has a plastic socket-type
bushing on each end. One end of this drive link is snap-fit over the ball stud on the right pivot lever arm, while the other end is snap-fit over the
top of the driver side drive link on the ball stud of the wiper motor crank arm.
-
Motor - The wiper motor is secured on the underside of the module bracket near the center with three screws. The wiper motor output shaft passes
through a hole in the module bracket, where 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 Positive Temperature Coefficient (PTC) circuit breaker.
-
Pivots - This module features two pivots. The two wiper pivot shafts have lever arms with ball studs at their base to accept the wiper linkage. The
upper end of all three pivot shafts has a threaded stud with a tapered and serrated area just below the threads to accept the left or right wiper arm
links.
The wiper module cannot be adjusted or repaired. The wiper motor is only available for separate service replacement. If any other component of the
module is inoperative or damaged, the entire front wiper module unit must be replaced.
