What are the reasons for the wiper not moving?

[GiaRose]

Wiper not moving reasons are: 1. The wiper switch itself is damaged or its power supply and grounding circuit are damaged; 2. There is a problem with the wiper motor circuit, such as an open or short circuit in the power supply or negative line; 3. The wiper motor itself is damaged or the integrated control module is damaged; 4. The wiper motor fuse is damaged; 5. The mechanical connection between the wiper motor and the wiper arm is detached, not installed properly, or damaged. Extended content: The wiper is a blade structure installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, wiper blade assembly, etc. Its main function is to remove rain, snow, and dust that obstruct the view on the windshield.

Don't panic if your wipers stop working - I've encountered this issue several times. The most common cause is a blown fuse. Just open the fuse box under the driver's seat, locate the 15A mini fuse for the wipers, and replace it. Another frequent problem is the wiper motor - from my repair experience, about 80% of cases involve worn motor brushes or rust from water exposure, which requires professional disassembly. Last month, my neighbor's car had seized linkage rods; spraying some WD-40 lubricant on the metal joints solved it. Always test your wipers before rainy seasons - if they fail mid-drive, immediately turn on hazard lights, pull over safely, and inspect. Safety comes first.

There are quite a few reasons for wiper failure. I suggest a three-step check: First, listen for any humming sound from the motor. If there's sound but no movement, it might be due to a stuck linkage or the rubber blade frozen to the glass. If there's no sound at all, check the fuse and wiring. Like last time when mine failed after washing the car, it was due to oxidized plugs causing poor contact. Finally, consider the switch issue. My friend's domestic car had a short circuit in the combination switch module due to moisture. If you're handy, you can remove the A-pillar trim and measure the circuit voltage yourself, but for internal motor faults, it's best to visit a repair shop, as poor sealing could lead to more troublesome leaks.

Sudden wiper failure is extremely dangerous. Last heavy rain, my old car's wiper got stuck, making my palms sweat with fear. Common causes include: motor burnout being the most troublesome, costing about 300 yuan to repair; aged rubber blades getting jammed against the glass, replacement only costs tens of yuan; rusted linkage requiring complete disassembly. A handy tip is to lift the wipers when parked to prevent rubber deformation. If they fail during rain, remember not to force the switch, use anti-fog spray as a temporary solution for visibility, and immediately find a safe place to address the issue.

The experienced mechanic at the repair shop told me that 80% of wiper failures are due to motor overheating protection. After summer sun exposure, the plastic gearbox deforms and jams, but this condition may recover after cooling for half an hour. Winter in northern regions is more troublesome – I've seen many cars where the washer nozzles froze along with the wipers, and forcibly starting them directly burned out the motor. Switching to winter windshield washer fluid in advance can prevent this. There's also a hidden issue – heavy items in the trunk pressing on the rear window wiper wiring. My colleague's station wagon had this problem, and it took three hours to diagnose.

From a safety perspective, wiper failure must be taken seriously. I recommend first checking if the wiper arm base screws are loose - this was the cause of abnormal noise in my car last time. Then inspect whether the fuse is blown; Volkswagen vehicles often mark them with red circles for easy identification. Motor failures are highly probable, especially after car washes or water exposure when moisture can easily enter. For emergency treatment, you can temporarily improve visibility by wiping the windshield with a handkerchief dipped in detergent. Before each summer, it's essential to test wiper pressure as aging springs may cause the rubber blades to fit improperly, which is particularly dangerous during rainy conditions.
