Why is the windshield wiper not moving?
4 Answers
Reasons why the wiper is not moving: 1. Open the engine cover and observe whether the transmission linkage is dislocated; 2. Check if the fuse is intact; 3. Disconnect the motor wire plug, turn on the power, and use a multimeter to measure if there is voltage; 4. If the fuse is intact but the motor has no voltage, check whether the wiring and the combination switch of the turn signal are intact; 5. Check for any burnt smell indicating a motor failure. The working principle of the wiper is: the motor on the wiper drives the output through the worm gear on the armature shaft and drives the output gear through the idler gear and idler shaft. The output arm connected to the wiper linkage is then manipulated by the output shaft. When the motor rotates, the output arm and linkage are driven to move back and forth.
The windshield wiper isn't moving, possibly due to motor failure. The motor drives the entire system and is prone to overheating and burning out after prolonged operation. If the switch doesn't respond, try replacing the fuse. Fuses are usually located in the engine compartment fuse box, and swapping in a new one is simple and straightforward. Poor switch contact is also common, as aging buttons may fail to transmit signals. Additionally, wiper blades stuck with debris or connecting rods rusted and jammed can cause the wiper to stiffen and stop moving. It's recommended to first check the fuse and switch yourself. If that doesn't work, head to a repair shop immediately to avoid reduced visibility during heavy rain, which increases accident risks. Regular maintenance can minimize these issues, such as cleaning wiper blades quarterly.
Don't panic if your windshield wipers suddenly stop working. Common causes include a blown fuse due to electrical overload—replacing it can restore normal function. Issues with the motor or switch failures are also frequent; if the control component fails, nothing will move. If this happens during rainy weather, visibility becomes dangerously poor—pull over immediately and turn on your hazard lights. I also recommend regularly spraying windshield washer fluid to keep the wipers flexible and prevent the linkage from rusting and jamming. Generally, simple problems can be fixed yourself, but for complex faults, consult a professional technician. Safe driving is always the top priority.
I've also encountered wipers not moving, most likely due to a blown fuse. Try replacing the fuse, located near the in-car fuse box. If that's not the issue, the motor might be burnt out or the switch contacts oxidized and failed. A rusted wiper linkage could also cause sticking—in such cases, pull over and check as soon as possible. Simple daily maintenance is crucial, like cleaning wiper blades to prevent dust buildup and ensure smooth system operation. Prevention is always better than emergency fixes, and regularly testing wiper functionality is basic knowledge.
