Wiper, Rear


WASH/WIPE

CIRCUIT OPERATION

INTERMITTENT OPERATION
When the rear wiper stalk is moved to the "on" position, then the rear wiper will perform two complete wipes and stop in the park position. After that, its operation will vary depending on the selected mode of the front wipers.

REVERSE GEAR WIPING
If reverse gear is selected while auxiliary or ignition is on and a front wiper function is selected, then the rear wiper will operate as well.

If reverse gear is selected while the front wipers are off (or performing a wash/wipe cycle) then the rear wiper will operate in the mode indicated by the rear wiper switch.

REAR SCREEN PROGRAMMED WASH/WIPE
If the rear wash/wipe switch is operated, the rear screen wash motor will operate for 1.5 seconds or for as long as the switch is held on, whichever is the longer. The rear wipe will be operated 0.5 seconds after the switch closed and will continue to operate until three full wipes have been completed after the washer motor has ceased it's operation.

WIPER OPERATION WITH SPEED DEPENDENCY ON
If the vehicle has speed dependent wipers, the wiper adapts its speed to the vehicle speed.

The speed barrier, where the wipers move between a faster or slower operation, is 2 mph.

HEADLIGHT WASH/WIPE
If the headlight switch is in the on position, the first and every alternate operation of the front screen wash switch will activate the headlight wash/wipe motor, which will operate for 2 seconds, regardless of the length of time the switch is pressed.
