General System Description

GENERAL INFORMATION

Low-speed (and high-speed) wiper operation
- When the wiper switch is placed in the LO position with the ignition switch in the ACC or ON position, wipers operate continuously at low speed.
- Placing the wiper switch in the HI position causes the wipers to operate at high speed.

Auto wiper stop operation
- When the wiper switch is placed in the OFF position, the cam contacts of wiper motor causes current to flow through the auto wiper stop circuit, allowing the wiper blades to cycle before they reach to the stop positions.

Intermittent wiper operation
- When the wiper switch is placed in the INT position with the ignition switch in ACC or ON position, the intermittent wiper relay is energized causing the intermittent wiper relay contacts to close and open repeatedly.
- When the contacts are closed, the wiper motor is energized.
- When the wiper motor is energized, the relay contacts open; however; the cam contacts keep the wiper motor energized until the wiper blades return to their stop position.

Washer-wiper operation
- When the washer switch is turned ON, the intermittent wiper relay contacts close causing wipers to cycle one to two times.

Remark
- The washer-wiper operates in the priority even during intermittent operation of the wiper.

Washer fluid level warning light
- When the washer fluid level goes down below a predetermined level with the ignition switch in ON position, the washer level switch makes the washer fluid level warning light illuminate.
