What to Do When the Wiper Blades Won't Move?

If the wiper blades won't move, you need to check whether the screws on the wiper are loose. Tightening the screws should resolve the issue. Below is an introduction to related information: Usage: When there are foreign objects such as mud or sand around the wiper blades, they can get stuck and prevent the wipers from moving. After removing the foreign objects, manually shaking the wipers a few times should allow them to function properly. Components: The wiper assembly includes components such as the motor, reducer, four-bar linkage mechanism, wiper arm spindle, and wiper blade assembly. Principle: When the wiper switch is pressed, the motor starts. The motor's rotational speed is converted into increased torque through the worm gear mechanism, which drives the swing arm. The swing arm then moves the four-bar linkage mechanism, causing the shaft installed on the front bulkhead to swing left and right. Finally, the shaft drives the wiper blades to sweep across the windshield.
The other day while driving, I encountered a situation where the windshield wipers wouldn't move. Don't panic right away, there could be several reasons. At first, I thought something might be stuck in the wiper arm, but upon checking, there was no foreign object. Next, I tried checking the fuse—the fuse box is usually located under the hood or below the driver's seat. Open it up and see if the fuse corresponding to the wipers is burnt black. Replacing it often solves the issue for many people. If the fuse is fine, the problem might be a faulty motor or linkage. The motor might hum but not move, while the linkage—the part connecting the wiper arm—could be rusted or worn, causing it to jam. Forcing it to operate might damage more components. At the time, I used a wet cloth to wipe the windshield as a temporary roadside solution. Later, when I took it to the repair shop, the technician confirmed it was a motor failure and replaced it. Remember, driving in the rain with malfunctioning wipers is very dangerous, so try to fix the issue as soon as possible.
When the wipers won't move, my first thought is: Is the fuse blown? This is the most common issue. Check the owner's manual to locate it and try replacing it with a new one. If the motor makes no sound and doesn't move, it's likely the motor is faulty or there's a linkage problem—rust or deformation in the linkage can cause it to jam, requiring lubrication or replacement. A faulty wiper switch or control module could also be the culprit, such as aged wiring disrupting the signal. If you're DIY-ing, check for loose connectors and gently wiggle the wiper arm to see if there's any abnormality. But don't recklessly disassemble complex parts at home to avoid causing more damage. It's best to drive to a reliable repair shop and let a professional diagnose it with proper tools—safety first.
My windshield wipers aren't moving, it's most likely a blown fuse. Just find a new fuse and replace it to solve the problem. It could also be that the wiper motor is broken - if the motor isn't turning, there'll be no sound. Or perhaps the linkage mechanism is stuck, making the movement stiff. A simple check will do: first turn off the engine, open the hood, locate the fuse box and check the wiper fuse condition; then try gently pushing the wiper arm - if it's stuck, don't force it. If all else fails, take it to a repair shop to avoid delaying your drive. Wiper malfunctions affect visibility, especially in rain, so address them promptly.
