Which button controls the wiper on a Mercedes-Benz car on rainy days?

The wiper of a Mercedes-Benz is integrated into the turn signal lever on the left side of the steering wheel. Due to the column shifter design of Mercedes-Benz models, the wiper switch control is integrated into the turn signal lever on the left side of the steering wheel. Wiper speed adjustment: Pushing the switch downward increases the wiper speed. Working principle: The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque, and its output shaft drives the four-link mechanism, which converts continuous rotational motion into a left-right swinging motion. The wiper motor adopts a 3-brush structure to facilitate speed adjustment. The intermittent time is controlled by the intermittent relay, which uses the motor's return switch contacts and the charging-discharging function of the relay's resistor-capacitor to make the wiper sweep at a certain cycle. The wiper blade rubber is the tool that directly removes rainwater and dirt from the glass. The blade rubber is pressed against the glass surface by a spring strip, and its lip must match the angle of the glass to achieve the required performance.
