Wiper/Washer Systems: Operation

When the lever is lifted up from its normal position, the wipers operate every 7 seconds. When the lever is pulled down to the first detent, the wipers operate for a single stroke. When the lever is pulled to the second detent, the wipers operate at low speed.

When the lever is moved to the third detent, high speed is selected. The front washer is operated by pulling the lever toward the driver. The wipers will cycle 2 to 3 times after the lever is released.

The rear wiper is off when the wiper lever switch is in the middle position. When the switch is moved toward the steering column, the rear wiper cycles every 5-15 seconds.

When the switch is moved away from the column, the wiper operates at normal speed. The rear washer runs when the button at the end of the lever is pressed. The wiper will operate 2 or 3 cycles after the button is released.

On all models except 760 GLE, the interval relays are located under a footplate near the left kick panel. The front relay is black and the rear relay is blue. On 760 GLE, interval relay is in central electrical unit in passenger compartment. Relay is rectangular (number 117) and is on far right of top row.
