Electronic circuit board controls all timing and washer commands. When washer switch is pressed for more than one second, washer fluid is sprayed on windshield as long as washer switch is held. Wiper will operate for 6 seconds after washer switch is released. Wiper motor operates in either low or high speed, depending on switch position. Rotating switch to DELAY position operates wipers intermittently. Delay can be varied by rotating switch back and forth. Immediate wiping can be activated by rotating switch to MIST position. Wiping action will continue as long as switch is held.
