Wiper and Washer Systems: Description and Operation

GENERAL INFORMATION

OPERATION

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.

Remote controlled mirror
- When the remote-controlled mirror switch is operated while the ignition key is in "ACC" or "ON" position, current flows through multi-purpose fuse No.7 remote-controlled mirror switch, remote-control mirror, remote-controlled mirror switch, and ground, causing the mirror to move.
