What to Do When the Wiper Doesn't Reset?
2 Answers
If the wiper cannot automatically reset, it may be due to aging wiper blades or dust and other debris stuck between the blades and the windshield, obstructing the wiper's reset. You can clean the wiper blades and windshield with a damp cloth, and replace the wiper or blades if necessary. It could also be caused by wiring issues, motor failure, or wiper switch malfunction, in which case it is recommended to visit an auto repair shop. Below are some maintenance tips for wipers: 1. Avoid oil contamination: If oil stains get on the windshield or wipers, they won't clean rainwater effectively. Although wipers rest on the windshield, they are often overlooked during routine maintenance. If you notice oil stains on the glass, use a glass cleaner to wipe the wiper blades and windshield when washing the car. 2. Keep in the lowest position when not in use: When not in use, the wipers should be placed in the lowest position, and the lower part of the windshield should be cleaned regularly to prevent debris from causing long-term pressure and deformation of the wiper blades. 3. Don't forget the wiper blades when washing the car: Although wipers rest on the windshield, they are often neglected during maintenance until problems arise during use. Maintaining wiper blades is actually very simple. Every time you wash the car, in addition to cleaning the windows, it's best to wipe the wiper blades with a glass cleaner to extend their lifespan.
I've seen this wiper not returning to position issue many times, mostly caused by faulty reset mechanism inside the wiper motor. There's a small spring and contact point inside the motor - over time either the spring gets loose or the contacts wear out, then it stops working. Could also be rusted linkage getting stuck or transmission gear teeth slipping. Last time when fixing Old Zhang's car, found his wiper joints were stuck by tree sap - just spent 60 bucks replacing a linkage rod to fix it. If this happens in winter, nine times out of ten the wiper blades are frozen to the windshield. Listen, when you notice this problem, don't force it - first turn off the switch and check at a safe spot, otherwise you might burn out the entire motor and cost yourself hundreds.
