One Windshield Wiper Stopped Working? How to Fix Broken Wiper That Won't Move (Most Common Solution)

I had just replaced the wiper blades with the top-of-the-line Bosch brand, and it was quite the disappointment when the fix didn't go according to plan. When I activated the wipers, one blade worked, while the other stayed limp. Worse yet, the working blade overtook the broken one, causing an unsettling noise.
In this video, I show you the most common cause of wiper problems. Usually, the nut holding the wiper arm onto the car becomes slack. In this case, I could immediately tell it was loose and was able to tighten it with my fingers. In an abundance of caution, I used a wrench to secure the 14mm nut for the long term. Usually, this issue can be resolved in a few minutes, and will save you a trip to the mechanic or dealer. #wipers #wiperblades #wiperblade
