DESCRIPTION





The front wiper module is secured with screws through four rubber grommet-type insulators (4) to the cowl plenum panel and the left front fender ledge. The module is located in the rear of the engine compartment where it 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 are the only visible components of the wiper module. The wiper module consists of the following major components:

- Bracket (5) - The wiper module bracket is a single die cast aluminum unit that includes provisions for mounting the wiper motor and wiper pivots as well as for the for rubber insulators used in mounting the bracket to the vehicle.
- Crank Arm (6) - 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, and has a long ball stud secured to the drive end to accept the wiper linkage.
- Linkage (3) - The two wiper linkage members are each constructed of stamped steel. A driver side drive link with 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 (7) - 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 (1 and 2) - This module features two driven pivots (2) and one drone pivot (1) for the articulating link of the right wiper arm. The two driven 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 wiper arm or the right wiper arm links.

The front wiper module cannot be adjusted or repaired. The front wiper motor is available for separate service replacement. If any other component of the module is ineffective or damaged, the entire front wiper module unit must be replaced.
