What is the reason why the car wiper cannot return to its position?

The reasons why the car wiper cannot return to its position include: a problem with the wiper motor, poor contact with the battery or wiring. It is recommended that the owner go to a repair shop for inspection and repair as soon as possible. The wiper, also known as the windshield wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and increase driving safety. 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, using a DC permanent magnet motor. The wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part.

As a seasoned driver with over 20 years of experience, I've encountered the wiper not returning to its original position several times. Once during heavy rain, the wipers suddenly stopped halfway, and I nearly hit the roadside. After stopping to check, I found that the small joint in the linkage was rusted and stuck, requiring some lubricant spray to move again. Another possibility is that the small gears inside the wiper motor are worn out, or poor switch contact can also cause the return to malfunction. I suggest you first check if the wiper arm is loose or clean out any leaves and debris in the slots, as they're especially prone to freezing in winter. A simple method is to try pulling out the wiper fuse and plugging it back in, which can sometimes resolve electrical control issues. If that doesn't work, don't push your luck—head to the repair shop immediately. Driving with malfunctioning wipers in the rain is extremely dangerous, with blurred vision and increased risk of skidding. For regular maintenance, remember to frequently clean the wiper area to prevent blockages, which can save you a lot of trouble.

Buddy, I'm a DIY car repair enthusiast. If the wipers aren't returning to their position, it's most likely due to a broken linkage from aging or worn-out worm gears in the motor. Poor contact in the switch button could also cause them to stop midway. Here's a simple way to check: first, turn off the engine and try manually pushing the wiper arm to see if it returns—if it's stuck, the mechanism is faulty. Clean the wiper groove to check for any debris like stones or ice chunks blocking it. Then, locate the wiper-related fuse in the fuse box and try unplugging and reinserting it. Avoid forcing it, as that can damage parts. If the internal sensor in the motor is faulty, you'll need to replace it—it's not expensive, but be careful if doing it yourself. Wiper failure on the highway is terrifying, as it can completely obscure your vision. I recommend applying some lubricating anti-rust spray to the wipers before rainy seasons. Don’t delay—address the issue early if it's minor.

I value vehicle safety. Wipers failing to reset severely impair visibility in rainy conditions, posing a driving hazard. Common causes include mechanical failures such as linkage fractures or internal motor wear, and switch issues can also prevent proper resetting. External factors like freezing or debris jamming are also frequent. Steps to address: immediately stop to clear obstructions; if unsuccessful, seek professional inspection promptly to avoid driving risks. Regular cleaning is recommended for prevention.
