What to Do If the Windshield Wiper Doesn't Return to Its Original Position?
4 Answers
If the windshield wiper doesn't return to its original position, the following checks should be performed: Check if the motor is functioning properly: After identifying the fault, follow the principle of checking external parts before internal ones and simple issues before complex ones to save time. Turn off the wiper motor and then turn it back on to check if the motor operates normally. If it does, then motor failure can be ruled out. Check if the wiper is stuck or has an open circuit: Once the motor is confirmed to be working properly, the next step is to check issues other than the motor, such as whether the wiper has an open circuit or is stuck. These are relatively simple tasks. Check if the hardware lacks lubrication, causing excessive friction: If none of the above issues are found, check if the hardware lacks lubrication, leading to excessive friction that prevents the spring from automatically returning to its original position. Then, apply lubricating oil to the surface of the card.
If you encounter a situation where the wiper is stuck in the middle, never force it. When I faced this issue before, I found that it might be due to worn motor gears or a jammed linkage mechanism. The simplest solution is to first park the car in a safe place, open the engine hood, and check if there are leaves or ice debris stuck in the mechanical arm. If it's caused by ice buildup, carefully use a heat gun to warm the wiper arm connection. During the rainy season, pay extra attention—if the wiper doesn’t return to its position, it can severely obstruct your vision. Once, I had to turn on my hazard lights and pull over to the emergency lane on the highway because of this issue. I recommend asking the mechanic to apply grease to the wiper linkage during every maintenance service—this area is often overlooked but is actually the most prone to rust and jamming. If you can’t fix it yourself, just take it to the repair shop to replace the motor assembly. Never disassemble the parts on your own—I’ve seen someone accidentally short-circuit the airbag wiring.
Windshield wiper not returning to the correct position? This issue commonly occurs in vehicles over five or six years old. I've found three main causes: deformation/displacement of the linkage mechanism, wear on the motor's reduction gears, or burnt contacts in the wiper switch. For DIY repairs, first disconnect the power to prevent accidental activation, then check for loose mounting screws. Pay special attention to abnormal wobbling at the motor drive shaft - last time my car had this issue, excessive play in this area caused misalignment. Regular maintenance with WD-40 spray on linkage joints works wonders, especially important to clear ice buildup immediately after snow in northern regions. Replacing the motor isn't actually difficult, but be sure to purchase a compatible model - online shopping makes this convenient nowadays. Finally, remember to adjust the rubber blade position properly, as ineffective wiping also compromises safety.
If the wipers don't return to their position, you need to immediately check the linkage mechanism. I've experienced this twice, both times due to worn plastic gears. First, make sure the wiper switch is turned off. If there's still a buzzing sound, it's likely a motor issue. Open the hood to observe the connecting rod's movement path, and use a flashlight to check for any sticking points. Replacing the linkage assembly yourself is quite troublesome, so it's better to go directly to a repair shop. Unusual noises from the wipers are usually a warning sign; it's recommended to replace the wiper blades every two years. In heavy snow, remember to remove the ice first before turning on the wipers, as forcing them to work can severely damage the motor.
