The wiper control switch is located on the right hand side of the steering column and controls all front and rear wiper functions.
Moving the switch up 1 position selects intermittent windshield wiper operation. The rotary potentiometer on the stalk selects 1 of 6 delay periods. When a rain/light sensor is incorporated into the system, the intermittent position also initiates wiper operation controlled by the rain/light sensor. The sensitivity of the rain/light sensor can be adjusted by rotating the rotary potentiometer to 1 of the 6 positions. Moving the switch up 1 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 windshield 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 front wash/wipe function. The washer pump will operate for as long as the switch is held. A short operation operates the pump momentarily and the wipers complete 3 full cycles before stopping. The headlamp washers will operate if programmed wash/wipe is selected and the headlamps are on. The power wash function can also be selected by depressing the button on the end of the stalk.
Rotating the outer ring of the wiper control switch to the first position selects the rear window wiper intermittent mode on. Rotating the outer ring of the wiper control switch further on to the second position selects the rear window wiper normal mode on. In intermittent mode, the rear window wiper will complete 1 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 5 full cycles with 3 automatic, short operations of the rear washer pump. The rear window wiper then operates in the rear window wiper on mode until selected off.
The rear window wiper also operates continuously if reverse gear is selected and the windshield wipers are on.
The wiper control switch comprises 8 switch positions and two intermittent rotary controls. The inner rotary control selects the intermittent delay between wipes. The outer rotary control selects the rear window wiper positions.
The switch positions each complete a combination of earth paths to 3 connections on the CJB (central junction box). The CJB interprets the selected combination of switches and operates the respective function accordingly.
