Windshield Wiper and Washer System
The windshield wiper system consists of the following 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 the following 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
NOTE: While in the interval wiper mode, it is normal to hear a slight click at the beginning of each wipe/pause cycle.
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.
