What Causes Windshield Wipers Not to Return to Their Original Position?
2 Answers
Windshield wipers not automatically returning to their original position may be caused by aging wiper blades or the presence of dust and other foreign objects trapped between the blade and the windshield, which obstructs the wiper's reset function. You can clean the wiper blade and windshield with a wet cloth, and replace the wiper or blade if necessary. It could also be due to wiring faults, motor failure, or wiper switch malfunction. These issues are recommended to be addressed at an auto repair shop. Below is some relevant information about windshield wipers: 1. There are generally two types of windshield wipers. One is the traditional intermittent type, which is the most common wiper with three to four segments, adjusted by the driver based on rain intensity and visibility. The other is the rain-sensing type, which has been increasingly used in mid-to-high-end models in recent years. A good wiper must be heat-resistant, cold-resistant, acid- and alkali-resistant, corrosion-resistant, fit snugly against the windshield, reduce motor load, produce low noise, have strong water-repellency, and be soft enough not to scratch the windshield, ensuring clear visibility. To ensure driving safety, it is best to replace the wiper annually. 2. Windshield wipers are crucial for driving safety, especially during rainy seasons. Regular inspection and maintenance are essential. Here are some tips: 1. Avoid oil stains: If the windshield or wipers accidentally come into contact with oil, they won't clean rainwater effectively. Although wipers rest on the windshield, they are often overlooked during daily maintenance. If oil stains are found on the glass, it's best to clean the wiper blade and glass with glass cleaner during car washing. 2. Keep in the lowest position when not in use: When not in use, windshield wipers should be placed in the lowest position, and the lower part of the windshield should be cleaned regularly to prevent foreign objects from causing long-term pressure on the wiper blade, leading to deformation. 3. Don't forget the wiper blade during car washing: Although wipers rest on the windshield, they are often overlooked during daily maintenance, and problems are only noticed when they are used. The maintenance method for wiper blades is simple. Every time you wash the car, besides cleaning the windows, it's best to wipe the wiper blade with glass cleaner to extend its lifespan.
Hey, I've encountered the issue of wipers not returning to their original position, which is usually due to mechanical component malfunctions. Thinking back, it could be that the linkage mechanism is deformed or loose. The linkage is responsible for the back-and-forth movement of the wipers during operation; if it's bent or worn, the position will shift and prevent them from returning to the original spot. Alternatively, the motor itself might be faulty—if the position sensor inside the motor is broken, it can't control the travel distance. I also remember one time when the wiper arm was stuck by a tree branch or there was too much snow buildup, increasing resistance and preventing the wipers from returning. Older cars are most prone to this issue due to lack of lubrication in the joints or long-term wear and aging. I suggest you first check around the wipers for any obstructions and gently push them to see if they move smoothly. If you can't fix it yourself, take it to a repair shop right away—they can use tools to test whether the linkage and motor current are functioning properly. Don't delay, especially since driving on highways with faulty wipers is too dangerous. Adding some lubricating grease during regular maintenance can help prevent this issue.
