When they notice their car’s windshield wipers not working properly, many drivers tend to think about the inconvenience it might bring during rainy or snowy days. One of the common culprits behind malfunctioning wipers is the windshield wiper motor. Understanding how to repair a windshield wiper motor can save them time and money. According to the National Highway Traffic Safety Administration, visibility issues account for 17% of all vehicle crashes (NHTSA, 2020). Ensuring that wipers are in top condition plays a crucial role in vehicle safety.
Steps to Repair Windshield Wiper Motor
Repairing a windshield wiper motor involves several steps. Here’s a step-by-step guide to help them through the process:
