Windshield Wiper System

The windshield wiper system consists of:
- Windshield wiper pivot arms
- Windshield wiper motor
- Wiper linkage and pivot shaft
- Multi-function switch
- Windshield wiper governor

Off/Low/High Speed
The windshield wiper motor is located in the engine compartment and is directly connected to the wiper linkage. The windshield wiper motor is a two-speed, permanent magnet motor. The windshield wiper motor has a brush rigging that permits the selection of LO or HI speed.







Interval
The windshield wiper/washer control knob on the multi-function switch controls the interval wiper function. When the windshield wiper/washer control knob is in any position in the S-F (interval: slow-fast) range, the windshield wipers make single wipes. The wipe cycle is timed by the desired pause set within the S-F range.

The windshield wiper governor is wired in series between the multi-function switch and the windshield wiper motor. It operates as a timer mechanism for the interval wiper function. It is located on the LH strut tower, directly below the hood support rod pivot.

Two-Speed
When the windshield wiper/washer control knob is in the LO position. the windshield wiper motor operates at low speed using the common brushes. When the windshield wiper/washer control knob is in the HI position. the current bypasses a portion of the armature winding. causing the windshield wiper motor to run faster.

When the windshield wiper/washer control knob is moved to the OFF position. the windshield wiper blades will cycle until they reach the park position and the windshield wiper motor will stop.
