Why do the wipers keep swinging?

First, in order to understand whywipersThe device will continue to swing, and we need to explore how it works. The wiper motor is the core of the entire system and is powered by a DC permanent magnet motor.mounted on the front windshieldWiperThe electric motor is usually designed to be integrated with the worm gear mechanism. The worm gear mechanism is used to achieve deceleration and torque increase, and the continuous rotational motion is converted into left and right swing motion through the four-bar linkage mechanism.

When we want to turn off the wiper on the rear windshield, we can do it through the control button of the rear wiper or the wiper adjustment lever. However, if the wipers still don't stop swinging despite these actions, it means there may be some malfunction that needs to be addressed.

First, we can check whether the wiper motor is faulty. If the wiper motor feels hot when you touch it, there is probably an internal short circuit and the motor needs to be replaced.

Another reason why the wipers may not stop working isfuseof poor contact. If the fuse has this problem, we need to replace it.

Additionally, a faulty switch may prevent the wipers from turning off. If a switch fails, we need to repair or replace it.

Finally, if none of the above fixes the problem, the wiper motor wiring may be faulty. In this case, we recommend disconnecting the negative terminal of the battery and sending the vehicle to a repair shop or 4S shop for further investigation.
