BMW 7 Series: Wiper Motor

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 wiper blades to judder
  • Alternating rest position of the wiper blades.

The wiper motor has two speed settings for wiping the windscreen.

The wiper motor receives information about the wiper stage via the LIN bus. The LIN-bus messages are evaluated by electronics in the wiper motor.

A constant speed is generated by the electronics, enabling consistent wiping by the windscreen wipers.

The wiper motor stores the wiper arms, and therefore also the wiper blades, outside the field of vision, as in the E65. In addition, they are stored on alternate sides. This prevents unnecessary wear on the wiper blades and they will remain pliant for longer.

Washer Fluid Pump

A washer fluid pump is located in the washer fluid reservoir for cleaning the windscreen. The pump is actuated directly by the junction box electronics.

Pump for Headlight Washer

A high pressure pump is used for the headlight washer system. The pump is activated via a relay in the front power distribution box.

Heated Washer Jets

Three heated water jets are used for the windscreen washer. The washer jets have a PTC resistor that automatically limits the power consumption.
