Intermittent

With the ignition switch in ON or START battery voltage is applied to the front wiper/washer switch, front wiper motor, and alarm and relay control unit through fuse C-5

When you turn the wiper switch to INT, battery voltage is applied to the alarm and relay control unit. The alarm and relay control unit momentarily energizes every 3 to 4 seconds or a variable time of every 2 to 20 seconds (depending on intermittent switch position) and applies battery voltage to the LO winding of the wiper motor. The wipers then move from the PARK position to the RUN position, and the PARK/RUN function takes over to eventually return the wipers to the PARK position when you turn the wiper switch OFF.
