What to Do If the Windshield Wipers Start by Themselves and Can't Be Turned Off?

Open the fuse box on the driver's side door to turn off the windshield wiper fuse. Below are the differences between traditional and beam wipers: 1. Traditional Wipers: These use multiple pressure points to ensure close contact between the wiper blade and the windshield. Due to the strong pressure required from the wiper arm, this can lead to fatigue in the wiper motor. The advantage is their sturdy housing, but the downside is poor flexibility during use. 2. Beam Wipers: The first advantage of beam wipers is their lightweight design. The second advantage is that they use a single pressure point, known as a flexible steel strip, which ensures tight contact with the edge of the wiper blade. This allows for effective pressure on the windshield with minimal force, ensuring a thorough and clean wipe without excessive pressure on the glass.
I've experienced the wipers moving non-stop, which is really annoying. The most common issue is a short circuit in the wiper switch contacts, causing them to stay on constantly. Or the relay might be faulty, stuck in the on position and unable to reset. Wiring shorts are also common, like when wires age, crack, and get wet, causing leakage. The rain sensor malfunctioning could be another cause if the car has automatic wipers. I'd recommend stopping the car immediately, turning off the engine, waiting a bit, and then restarting to try a system reset. Next, check the wiper fuse in the fuse box to see if it's blown, and replace it if necessary. If the problem persists, don't tinker with the switch or relay yourself—it's easy to get shocked or damage other circuits. Non-stop wipers are particularly dangerous as they obstruct your view, and distracted driving could scratch the windshield. It's safer to take it to a professional shop right away; DIY attempts might end up costing more time and money.
