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