What are the reasons for the wiper not returning to its original position?

The reasons for the wiper not returning to its original position are: 1. Aging of the wiper rubber; 2. Presence of dust or other foreign objects between the rubber and the windshield; 3. Wiring fault; 4. Motor fault; 5. Wiper switch fault. The function of the wiper is to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. The method for removing the wiper is: 1. Fully lift the wiper and adjust the angle of the blade; 2. Change the angle of the wiper blade so that it forms a 90-degree angle with the wiper arm; 3. Once positioned at the angle, you can start the removal process. Lift the rubber blade, remove the entire wiper blade, separate the rubber blade horizontally, press down on the main bracket, and the entire wiper blade can be removed.
I think the wipers not returning to their original position might be due to the wiper linkage being stuck or a problem with the motor. I've driven quite a few cars and encountered this issue several times, especially during heavy rain when the wipers not working can be very dangerous. The linkage is that metal rod connecting the motor to the wiper arms; over time, corrosion or rust from rainwater can cause it to bend and get stuck, preventing the wipers from moving and leaving them halfway. As for the motor, if the internal gears are worn or there's an electrical fault, the wipers may move sluggishly and stop midway. Additionally, if the wiper arms are installed too tightly or have become loose, it can affect their positioning, causing them not to return accurately. I recommend checking the wipers' movement regularly before driving to ensure they operate smoothly and aren't clogged with debris. If you notice any issues, get them fixed immediately—don't delay, because safety comes first, especially when driving at night. Also, different car models have varying designs, and older cars are more prone to such failures. Regular maintenance can prevent most problems, including clearing debris under the windshield to protect the linkage—something I've learned from experience. Addressing small issues early can save you from bigger troubles later.
