Why is the windshield wiper not moving?

Reasons why the windshield wiper is not moving: 1. The fuse is blown, causing the wiper to malfunction. Open the fuse box to check and replace the corresponding fuse; 2. The motor is burnt out. Turn on the car ignition to power on, open the front hood and activate the wiper. If it's not damaged, you should hear the sound of the motor running, which is quite noticeable. However, if there is no sound and a burning smell is present, it indicates motor failure. The windshield wiper is a blade structure installed in front of the windshield, consisting of components such as the motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Its primary function is to clear rain, snow, and dust from the windshield that obstruct visibility.
Yesterday, while helping my cousin check out a car, I encountered this exact issue—the wipers wouldn't move, and the system needed inspection. First, check if the fuse is blown. Open the small box on the left side of the driver's seat and replace it with a 20A fuse, which is very cheap. Leaves stuck under the windshield can jam the wiper arm, and if the rubber blade is frozen to the glass, forcing it might burn out the motor. The most troublesome issue is when the motor gears rust solid. Last time I took it apart, I found that accumulated water had corroded the linkage, and replacing the whole set cost over 300 yuan. Wiring aging and short circuits are even more dangerous, as rain-induced electrical leaks could fry the car's computer. Always remember to return the wipers to their proper position when turning them off—leaving them misaligned for long periods can loosen the springs.
