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.

How Do You Know If Wiper Arm Tension Is Too Weak?
That’s the question many drivers ask. One easy test is to lift each wiper arm off the windshield. If it doesn’t spring back firmly when released, the tension may be fading. Another sign? Uneven wiping or sections of the windshield that stay foggy, no matter how new the blades are.
Wiper arm springs lose their strength over time due to constant use, heat exposure, and even exposure to UV rays. Rust or grime buildup around the pivot point can also cause the arm to stick, reducing the pressure needed for proper contact. That’s why a quick inspection every few months—or during regular maintenance—is a smart habit.
At Auction Direct USA, technicians recommend checking both the arms and blades together. If tension feels weak or the arms are corroded, a quick replacement can restore full wiping power. It’s a small fix that pays off big when driving visibility matters most.
