How to Adjust the Speed of BMW Windshield Wipers?
3 Answers
There is a sensitivity adjustment button on the lever of BMW windshield wipers, which is used to adjust the speed settings. Below is a detailed introduction to BMW windshield wipers: 1. Function: The wiper, also known as a windscreen wiper, water wiper, or windshield wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. Due to legal requirements, almost all vehicles worldwide are equipped with wipers. Rear windows of hatchbacks and SUVs also have wipers. Apart from cars, other transportation vehicles such as trains and trams are also equipped with wipers. Some engineering machinery, like cranes, also have wipers installed. 2. 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-bar linkage mechanism, converting continuous rotational motion into left-right swinging motion through the four-bar linkage mechanism.
As an experienced driver who has driven BMWs a few times, adjusting the wipers is quite convenient. There's a lever on the right side of the steering wheel with a small knob or ring that you can turn to change the speed. Typically, there are settings for low speed, high speed, and intermittent mode. The intermittent mode also allows for fine-tuning the time interval, such as slowing it down during light drizzles to avoid excessive wiping and conserve energy. The exact position may vary slightly across different BMW models, but the overall operation is similar. Don't overlook wiper blade maintenance when using them—clean them promptly when dirty to extend their lifespan. Safety comes first when driving in the rain, so adjust the wipers in real-time based on rainfall to maintain clear visibility. Remember to check the wiper system for freezing or aging during seasonal changes.
I tried driving my friend's BMW, and the wiper speed was easy to adjust. There's a ring on the control stalk near the steering wheel—just turn it to change the speed. It shifts gradually from slow to fast, making it convenient to adapt to various weather conditions. When driving in the rain, you need to be flexible: set it to intermittent for light rain and switch to high speed for heavy downpours. Some higher-end models come with an automatic wiper function, but I prefer manual control for peace of mind. By the way, wiper fluid is crucial—running low affects cleaning performance and can cause noise. Regularly check the electrical connections to avoid malfunctions. The design is user-friendly and easy to use.
