What Are the Reasons for a Car Wiper Not Moving?
2 Answers
Reasons for a car wiper not moving: 1. The wiper switch itself is damaged or its power supply or grounding circuit is faulty; 2. There is an issue with the wiper motor circuit, such as an open or short circuit in the power supply or negative line; 3. The wiper motor itself is damaged or the integrated control module with the motor is faulty; 4. The wiper motor fuse is blown; 5. The mechanical linkage between the wiper motor and the wiper arm is detached, improperly installed, or damaged. The wiper is a tool on the windshield of motor vehicles designed to simply clear rainwater and other debris that may obstruct vision. The primary condition for using the wiper is to operate it when there is rainwater. Never use it dry without water, as this can damage the rubber blade of the wiper and the wiper motor.
I've been driving for over 20 years and encountered non-moving wipers several times. The most common issue is a blown fuse - there's a fuse box under the hood, just check the manual to locate and replace it. Or it could be a faulty motor; if you don't hear the humming sound when switching it on, suspect this. Last time during rain failure, I tried shaking the wiper arm to check if the linkage was rust-jammed - adding lubricant might help. Poor switch contact can also cause trouble, with dashboard lights flickering. When automatic wiper sensors fail, they just stop working - I almost had an accident on the highway that time. Pull over immediately to check - fix minor issues yourself, leave complex ones to professionals. Non-functioning wipers are extremely dangerous, so regular anti-rust checks are essential.
