What Are the Reasons for the Wiper Not Working?

[Gale]

There are several reasons why the wiper may not be working: 1. Check the screw area: If the wiper is not working, check if the screws are loose and tighten them if necessary. 2. Check for debris: If the wiper is not working, check if there is any debris like mud around the wiper, which can block it and prevent it from moving. After cleaning the debris, shake it manually a few times to see if it works. 3. Check the fuse: If the wiper is not working, open the hood and check if the transmission linkage is dislocated. Next, check if the fuse is intact. If the fuse is intact but there is no voltage at the motor, check the wiring and the turn signal combination switch. If there is normal voltage at the wiper motor when the power is on, the motor may be damaged. 4. Check the rubber: Pay attention to whether the connection between the rod and the wiper arm is correct. Lift the wiper and touch it with your fingers to check for any damage to the rubber wiper and the elasticity of the rubber blade. If the blade is aged, hardened, or cracked, it needs to be replaced.

Last time when my windshield wipers stopped working, I researched and found there could be various causes. A common issue is a blown fuse – when it melts in the fuse box, the entire circuit loses power, naturally preventing operation. The motor itself might also fail, especially after frequent use during rainy seasons leading to aging or water-induced short circuits. Switch problems are another culprit, where poor button contact or wiring faults prevent signal transmission. If the linkage transmission part gets stuck or the gears wear out, movement becomes impossible. Electrical issues like loose connections or oxidized plugs can also interrupt current flow. In more modern cars, faulty rain sensors may cause automatic control malfunctions. So when wipers fail, first check the fuse location – always remove the key for safety before troubleshooting. Minimize using wipers to scrape ice/frost during normal use to avoid overload and reduce problems.

I often encounter the wipers not moving when driving an old car, which is very dangerous from a safety perspective. Driving in the rain with blurred vision and failed wipers significantly increases the risk of accidents. Possible causes include power interruption—the most common being a blown fuse, motor response failure preventing movement, or a malfunctioning switch button which is even more troublesome. Sometimes, the wiper arm gets stuck by foreign objects and can't move. For solutions, it's recommended to immediately pull over safely, turn on the hazard lights, and check if the fuse is burnt out and replace it. Try pressing the switch button multiple times to see if there's any response, and tapping the motor lightly might provide a temporary fix. However, safety comes first—don't force the car to move. It's more reliable to visit an auto repair shop as soon as possible for a thorough inspection.

I think the wiper not moving is mostly a simple malfunction. Last time, I first checked if there were any leaves blocking under the wiper blade and removed the obstruction. Then, I inspected the fuse box, found the corresponding position, and tried replacing it with a new fuse—this step is easy to operate. I pressed the switch a few times, and if there was no movement, it might be an internal failure. I felt around the motor connection for any looseness. I regularly clean the wiper system to reduce the chance of jamming. If these simple fixes don't work, I drive to a professional shop to test the wiring and avoid tampering to prevent electric shock.

From a maintenance perspective, I've repaired wipers and found the costs reasonable. Minor issues like a blown fuse can be fixed by replacing it for just a few dollars. Replacing the motor with a new part might cost over two hundred, but it lasts longer. Repairing the switch or control module usually stays under a hundred, much cheaper than letting it escalate into major repairs. I recommend finding a reliable repair shop to diagnose the circuit with a scanner, rather than risking costly DIY mistakes just to save money. Driving with faulty wipers in the rain is a serious hazard—it's worth spending on repairs to avoid potential accidents. Don't delay until it causes a crash.

I believe preventing wiper issues can save a lot of trouble. During regular maintenance, I check the wiper system: clean accumulated dust on the wiper blades, maintain lubrication to avoid dry wiping; confirm the fuse is not burnt; keep the switch button clean to prevent oxidation; turn off automatic mode promptly after rainy days to reduce motor load. These simple and easy habits extend wiper lifespan by over five years, avoiding sudden failures that threaten driving safety.
