What Causes Windshield Wipers to Not Return to Their Original Position?

[McJulian]

Windshield wipers failing to return to their original position can be caused by several issues, including a malfunction in the wiper drive motor, external wiper faults, or wiring problems. Below are some maintenance methods for windshield wipers: 1. Check if the motor is functioning properly: After understanding the various scenarios of the aforementioned faults, the inspection should follow the principle of starting with external factors before internal ones, and simple checks before complex ones to minimize time consumption. Turn off the wiper motor, then turn it back on to check if the motor operates normally. If it does, then motor malfunction can be ruled out. 2. Inspect hardware lubrication: Check if the hardware lacks lubrication, leading to excessive friction that prevents the spring from automatically returning to its original position. Applying lubricant to the card surface can help alleviate this issue.
