DESCRIPTION







The wiper module is secured with screws through three rubber grommet-type insulators (5) to the cowl plenum panel. The module is concealed beneath the molded plastic cowl plenum cover/grille panel between the base of the windshield 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 consists of a long tubular steel main member (2) that has a die cast pivot bracket (1) at each end to which the two wiper pivots are secured. A stamped steel clamp secures the center of the tubular member to the die cast bracket integral to the wiper motor with two screws.
- Crank Arm (10) - 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 long ball stud secured to the drive end to accept the wiper linkage.
- Linkage (2) - Two tubular steel drive links connect the wiper motor crank arm to the wiper pivot lever arms. The left side drive link has a plastic socket-type bushing (6) on each end. The right 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 (8) of its respective pivot. The right 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 left side drive link is snap-fit over the exposed end of the wiper motor crank arm ball stud.
- Motor (11) - The wiper motor features an integral die cast bracket to which the wiper module bracket is secured with a stamped steel clamp and two screws near the top and which has a single rubber insulated mounting ear at the bottom. This die casting also serves as the wiper motor transmission housing from which the wiper motor output shaft exits. 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 connect the wiper motor to the vehicle electrical system through a dedicated take out and connector of the headlamp and dash wire harness.
- Pivots (2) - 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 serrated driver with a keyway. 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 ineffective or damaged, the entire wiper module unit must be replaced.
