Windshield Wiper System

The windshield wiper system consists of the following components:
- Windshield wiper motor mounted to underside of dash panel
- Windshield wiper mounting arm and pivot shaft mounted to underside of dash panel and connected to windshield wiper motor output arm
- Windshield wiper governor behind the instrument panel between the radio chassis and steering column
- Multi-function switch, which features a rotary wiper switch and a push-type washer actuator
- RH windshield wiper pivot arm
- LH windshield wiper pivot arm
- 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 and the windshield wiper motor runs 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 park switch contacts open, the windshield wiper motor stops in the park position.







INTERVAL

NOTE: When using interval wipers, the first wipe may not occur until after a pause of up to 17 seconds.

When the multi-function switch is in the interval position:
- The wipers make single wipes separated by pause.
- The control knob on the end of the multi-function switch sets the length of the pause (from approximately 1-17 seconds).
- The length of pause decreases as the knob is rotated away from OFF and increases as the knob is rotated toward OFF.
- It is normal to hear a slight ticking sound at the beginning of each wipe/pause cycle. This sound is from the wiper control module's relay.
