Low Speed And High Speed Operation

• When the wiper switch moves to the 1 (low) position, current (1) flows through the wiper switch to the wiper motor, then to ground. The wipers operate at low speed.
• When the wiper switch moves to the 2 (high) position, current (2) flows through the wiper switch to the wiper motor, then to ground. The wipers operate at high speed.
• When the wiper switch returns to the OFF position, the autostop function activates and the wipers stop at the park position.

Autostop Function

• While the wipers are operating, the autostop switch remains on except when the wipers are in the park position. Current flows through the INT relay to the wiper switch, wiper motor, then to ground. Thus, the wipers continue to operate until they reach the park position even if the wiper switch moves to the OFF position.

Intermittent Wiper Operation

• When the wiper switch moves to the INT position, the intermittent wiper (INT) relay turns on, and current flows through the INT relay to the wiper switch, wiper motor, then to ground. The wipers operate at low speed.
• When the preset period of time has passed, the INT relay turns off. The current stops flowing through the wiper motor. The autostop function activates, and the wipers stop at the park position. Cycling through this sequence of operations, the wipers operate at specified intervals.
