BMW 7 Series: Wiper Switch on the Steering Column Stalk
The wiper switch on the steering column stalk with the following functions is
located in the steering column
switch cluster:
- Intermittent wipe
- Wipe in stages 1 and 2
- Windscreen washer
- Headlight washer
- Switch for the rain/lights/solar/condensation sensor
- Indicator for activated rain/lights/solar/condensation sensor.
The wiper switch has sliding contacts that are located on the circuit board
for the steering column switch
cluster. The switch functions are realized by means of these sliding contacts.
The interval switch is a four-stage switch. Each stage produces different input
values in the steering column
switch cluster. The input values are evaluated for setting the sensitivity of
the rain/lights/solar/condensation
sensor or the intermittent wipe stage.
The button for the rain/lights/solar/condensation sensor is designed as an
ground-switching button. It is required
for switching on the rain/lights/solar/condensation sensor. The LED is
illuminated when the
rain/lights/solar/condensation sensor is activated.

READ NEXT:
The front wiper motor is a little smaller than the wiper motor in the E65.
Advantages of the wiper motor:
Lighter
Less noise
Reversing wiper motor
Stable wiper speed
Reduced tendency of the wipe
