Why Wiper Arm Tension Needs Checking—Not Just the Blades 

It’s easy to assume that replacing worn-out wiper blades is all it takes for a clear windshield. But at Auction Direct USA in Raleigh, NC, technicians often remind drivers that there’s more to it—specifically, why wiper arm tension needs checking—not just the blades. That small spring-loaded arm attached to the wiper blade plays a bigger role than most realize, especially when the weather turns nasty. 

Wiper arms might not seem like high-maintenance parts, but they work hard every time the switch is flipped. They press the blades firmly against the windshield, clearing away rain, dirt, and bugs. When the tension weakens, though, even brand-new blades can leave behind streaks, chatter across the glass, or completely miss sections of the windshield. And that’s not just annoying—it can be downright dangerous when driving through heavy rain or snow.
