When you take to the road in your Mercedes-Benz S420, you need your wipers to remove the dirt and debris that obstructs the view on your windshield. The motor is responsible for pushing your wiper blades back and forth. When any of the components in the windshield wiper motor system breakdown from damage or wear and tear, only a replacement of those parts will do.
Sometimes you'll notice that your wiper blades will squeak and scratch against your windshield, or that they no longer perform in sync. Those are tell-tale signs that something is amiss, and you'll need to replace the defective parts. StockWiseAuto.com has a wide array of auto parts for you to keep your Mercedes-Benz S420 safe and properly maintained for many miles to come.
