What to Do When the Wiper Doesn't Reset?

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.
My old car once had the wipers stuck halfway, which was really embarrassing. Later I found out it was caused by the wiper arm's mounting bolt being loose, causing angle misalignment. Adjusting the position with a wrench fixed it. If rust causes sticking, spraying WD-40 and letting it sit for half an hour before moving works great. Once I pulled the fuse while washing the car and forgot to put it back, resulting in completely frozen wipers – so remember to check the wiper fuse box under the dashboard. Actually, if you're handy, removing the wiper cover to check for linkage deformation isn't too difficult, but if the motor's broken, it's best to have a professional shop replace it – the disassembly and reassembly require real skill.
Don't panic if your wipers won't return to position - it's likely a mechanical issue. First, park your car securely, turn off the wipers, and restart the system. If that doesn't work, check if the wiper arm is obstructed by leaves. If you've recently had your windshield replaced, improper installation angle could be the culprit. During maintenance, I recommend having technicians thoroughly inspect the wiper system: gear wear, linkage lubrication, and motor voltage. These components typically last 6-7 years, but acid rain can accelerate aging. Remember to test wiper reset function before rainy season - safety is no trivial matter.
