Windshield Wiper System

The windshield wiper system consists of these components:
^ Windshield wiper motor attached to the cowl top extension.
^ Windshield wiper mounting arm and pivot shaft connected to windshield wiper motor.
^ Multi-function switch which features a rotary wiper switch and push-type washer actuator.
^ Windshield wiper governor located behind instrument panel, near top of LH cowl panel.
^ RH windshield wiper pivot arm.
^ LH windshield wiper pivot arm.
^ Two windshield wiper blades.
^ Windshield washer system.

Off/Low/High Speed
The two-speed, permanent magnet, three brush electric windshield wiper motor operates in this manner:
^ A brush rigging permits selection of low or high speed.
^ When the multi-function switch is in LO position, the common brush and the blue/orange wire brush are used and the windshield wiper motor operates at low speed.
^ When the multi-function switch is in HI position, the common brush and the white wire brush are used. Electric current bypasses a portion of the armature winding, causing the windshield wiper motor to run at high speed.
^ When the multi-function switch is moved to the OFF position, the windshield wiper motor will continue at low speed until the multi-function switch outer contacts open. When the wiper park switch contacts open, the windshield wiper motor stops in the PARK position.







Interval
When the multi-function switch is in the interval position:
^ The rotary switch on the end of the multi-function switch is rotated to set the length of pause between wipes.
^ The wipers make single wipes separated by a pause.
^ The length of the pause can be set from approximately 1 to 17 seconds and decreases as the rotary switch is rotated away from off.

While in the interval wiper mode:
^ It is normal to hear a slight click at the beginning of each wipe/pause cycle.
