What Causes Windshield Wipers Not Returning to Their Original Position?

[TeaganFitz]

Windshield wipers not returning to their original position are generally caused by the following three main reasons: failure of the wiper drive motor; external wiper failure; or circuit failure. Below is the relevant information: 1. Check if the motor is functioning properly: First, after understanding the various situations of the above faults, we should follow the principle of checking from the outside to the inside and from simple to difficult to reduce time consumption. Turn off the wiper motor, then turn it back on to check if the motor operates normally. If it does, then motor failure can be ruled out. 2. Check if the wiper is stuck or has an open circuit: Once the motor is confirmed to be functioning, the next step is to check for issues other than the motor, such as whether the wiper has an open circuit or is stuck, which are relatively simple checks. 3. Check if the hardware lacks lubrication: If none of the above situations occur, check if insufficient lubrication of the hardware causes excessive friction, preventing the spring from automatically returning to its original position. Then, apply lubricating oil to the surface of the card.
