Why does the wiper move once and then stop?

[VonChristian]

The reasons why the wiper moves once and then stops: 1. The wiper motor fuse is damaged; 2. The control module integrated with the motor is damaged; 3. The mechanical structure connecting the wiper motor and the wiper arm is detached, improperly installed, or damaged; 4. The wiper switch is damaged or its power supply or grounding circuit is damaged; 5. The negative circuit of the wiper motor is open or short-circuited. The wiper, also known as the windshield wiper or windscreen wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. The wiper consists of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly.

My old car had the same issue before - the wiper would move once and then completely stop working. This is usually caused by a faulty wiper motor. Either the gears inside the motor get jammed or there's a short circuit in the wiring. Continuous rain can sometimes allow water to seep into the motor and burn it out. Another possibility is the wiper linkage becoming disconnected - if the metal connecting rods rust solid or break, the entire transmission mechanism fails. When I checked mine by removing the wiper cover panel, I found the linkage joint had loosened, and tightening it with a wrench fixed the problem. If you're not comfortable doing it yourself, better take it to a repair shop. Also remember to regularly clean leaves and debris from the wiper trough - accumulated debris can jam the mechanical parts. I now apply some grease to the wiper pivot every six months as maintenance.

I've repaired this issue on many vehicles, and it's usually a mechanical problem with the wiper system. The key is to check if the motor is working: if you can hear the motor humming when you press the switch but the wipers don't move, it's 90% likely that the linkage has come off or is stuck due to rust. If there's no response at all, you need to check the fuse and circuit. In the front fuse box, there's a fuse marked with a wiper symbol - if it's blown, replace it with a 15A one. When troubleshooting on your own, remember to prioritize safety: remove the key before operating. Additionally, in winter, ice can freeze the wiper arms, so you'll need to de-ice them before use. It's recommended to inspect the wiper mechanism every 20,000 kilometers, as aging rubber components can also increase the load on the motor.
