WIPERS AND WASHERS

DESCRIPTION AND OPERATION

84-7

Wiper Control Column Switch

1 Wash/wipe control column switch
2 Intermittent delay rotary control
3 Programme wash/wipe position
4 Fast wipe position
5 Normal wipe position

6 Intermittent wipe position
7 Flick wipe position
8 Programme wash/wipe position
9 Rear wash/wipe position

10 Rear wipe position

The wiper control column switch is located on the right hand side of the steering column and controls all front and rear 
wiper functions. 

Moving the switch up one position selects intermittent front wiper operation. The rotary potentiometer on the stalk 
selects one of four delay periods. When a rain sensor is incorporated into the system, the intermittent position also 
initiates wiper operation controlled by the rain sensor. The sensitivity of the rain sensor can be adjusted by rotating 
the rotary potentiometer to one of the four positions. Moving the switch up one further position selects normal (slow) 
continuous wiper operation. Moving the switch up to the last position selects fast continuous wiper operation.

Moving the switch down selects the flick wipe function. The front wipers will operate at normal speed for as long as 
the flick wipe switch position is operated and will stop at the park position when the switch is released.

Moving the switch rearwards, towards the driver, selects the programmed front wash/wipe function. The windscreen 
washer pump will operate for as long as the switch is held. A short operation operates the pump momentarily and the 
wipers complete three full cycles before stopping. When headlamp wash/wipe is fitted, the headlamp washers and 
wipers will operate if programmed wash/wipe is selected and the headlamps are on. The wash/wipe function can also 
be selected by depressing the button on the end of the stalk.

Moving the switch forwards to the first switch position selects the rear wiper on. The rear wiper will complete one full 
cycle and will then operate on an intermittent function until selected off. The intermittent delay between wipes can be 
adjusted by selecting the wiper on, then off and then on again. Moving the switch forward to the second position 
selects the programmed rear wash/wipe function. The wiper completes five full cycle with three automatic, short 
operations of the rear washer pump. The rear wiper then operates in the rear wiper on mode until selected off.

The rear wiper also operates continuously if reverse gear is selected and the front wipers are on.

The wiper control column switch comprises 8 switch positions and the intermittent rotary control. The switch positions 
each complete a combination of earth paths to three connections on the BCU. The BCU interprets the selected 
combination of switches and operates the respective function accordingly.
