Description And Operation: Overview

The wipers and washers system functions on receipt of requests made by the driver or the rain/light sensor. All wiper functions for the front and rear wipers are controlled from the right steering column multifunction switch.

The wiper and washer system comprises:

• Windshield and rear window wiper motors
• A windshield wiper linkage
• Two front and one rear window wiper arms and blades
• Three front heated washer jets and one rear washer jet
• Two headlamp washer jets
• A windshield washer reservoir, a front/rear washer pump and a headlamp washer pump
• A wiper control switch
• A rain/light sensor.

The wiper system is equipped with a rain/light sensor, which controls the automatic wiper functions and also the automatic lighting functions. The sensor, located below the interior rear view mirror, detects rain drops on the windshield and automatically operates the wipers in the intermittent mode. The column stalk switch must be in the intermittent position for rain sensor controlled wiper operation.

For additional information, refer to: EXTERIOR LIGHTING .

The windshield wiper system has 4 wiper stages of operation and 4 intermittent wiper delay periods. The 4 wiper stages are as follows:

• Flick wipe
• Intermittent
• Normal (slow) speed continuous
• Fast speed continuous.

The intermittent, normal and fast speeds are affected by road speed. The intermittent wiper delay periods change with the road speed, with the delay decreasing as the road speed increases. The normal continuous operation changes to intermittent operation when the vehicle is stationary.

The wipers and washers operate with the ignition in power mode 4 or 6. Wiper functions are suspended during engine cranking to reduce battery power consumption under high load conditions.

Diagnostic information for the wiper system is available and can be retrieved using the Land Rover approved diagnostic system.
