Why Won't the Car's Windshield Wipers Move?

[GriffinFitz]

The reasons why the car's windshield wipers won't move: 1. There is an issue with the power supply to the wiper motor, commonly caused by a blown wiper motor fuse, preventing the wipers from functioning properly; 2. The wiper motor itself is damaged, either the motor or its integrated control module is faulty, and replacement is necessary after inspection confirms the damage; 3. The mechanical linkage between the wiper motor and the wiper arm is detached, improperly installed, or damaged; 4. The wiper switch itself is damaged or its power supply grounding circuit is faulty; 5. There is an issue with the wiper motor wiring, such as an open or short circuit in the power supply or ground lines.

Oh, I've been driving for over a decade and encountered many wiper failures. The most common issue is a blown fuse—it's located in the engine compartment's fuse box. Just find the label corresponding to the wipers, pull it out to check if it's blackened, and replace it with a new one. Wiper motor malfunctions also occur frequently; if you don't hear any humming sound, it might be broken. For poor contact in switches or knobs, spray some cleaner and wipe them. Another issue is wiring short circuits, especially prone during rainy days when water gets in. If mechanically jammed—like being frozen or blocked by leaves—manual cleaning is needed. These are all quite dangerous; in rainy conditions with poor visibility, first turn on hazard lights and pull over. Regular inspections can prevent many troubles.

During my last road trip, the wipers suddenly stopped working, which was really scary. Experience tells me that a blown fuse is the number one cause, and replacing it is quick and easy. If the wiper motor is humming but not moving, it might be due to rusted or worn linkage—lubrication or part replacement may be needed. A switch with no springiness could indicate internal contact issues. A faulty relay can cause the system to fail; check the instructions on the fuse box cover. It's advisable not to force the wipers by hand and to keep the windshield clear of debris. If this happens during rain, slow down and pull over immediately—forcing them to work can damage the electrical system.

Hey, there are many reasons why wipers don't move. A blown fuse is the most common issue, located in the engine compartment fuse box. If the wiper motor is burned out or the bearings are stuck, try listening for sounds to diagnose. Oxidized switch contacts can cause signal transmission failure. For short circuits or open circuits in the wiring, use a multimeter to check voltage. Mechanical failures in the wiper arm or linkage, such as damaged gears or frozen ice, could also be the cause. Malfunctioning sensors in automatic wipers might be another reason. It's recommended to start with simple checks, like replacing the fuse, otherwise seek professional repair—don't overlook safety.
