Why doesn't the wiper move when turned on?
2 Answers
Here are the reasons why the car wiper may not move: 1. Open the engine cover to observe if the transmission linkage is dislocated. 2. Check if the fuse is intact. 3. Disconnect the motor wire plug, turn on the power, and use a multimeter to measure if there is voltage. 4. If the fuse is intact but there is no voltage at the motor, check if the wiring and the combination switch for the turn signals are intact. 5. If the power is turned on and normal voltage is measured at the wiper motor, consider whether the motor is damaged. Here are the maintenance methods for car wipers: 1. Every time you wash the car, in addition to cleaning the windows, it's best to also wipe the wiper blades with glass cleaner to extend their lifespan. 2. Spray some cleaning solution, then activate the wiper to observe if its movement is smooth. Listen carefully for any loud "scraping" sounds. If present, it indicates that the wiper is pressing too hard against the glass and requires appropriate adjustment. After the wiper sweeps one or two times, check if there is any water left on the windshield and observe whether any scratches are left.
Once I encountered heavy rain on the highway when the wipers suddenly stopped working. It was so dangerous that I almost hit the guardrail. After stopping to check, I found out it was a blown fuse caused by a short circuit due to aging wires, which led to excessive current. Later, I learned to always check the fuse box before it rains. It's located under the hood and easy to find. If the wipers still don't move, it might be a faulty motor or switch malfunction. During regular maintenance, it's important to clear debris from the wiper arms to prevent jamming. Don't delay in such situations—go straight to the repair shop. Driving with poor visibility in the rain is too dangerous. Safety comes first; don't skimp on small expenses.
