Here’s the reality: If your windshield wipers are catching, skipping, or hitting each other, something is off—and ignoring it usually makes it worse. The good news is most of these problems come down to alignment, wear, or simple installation mistakes, not expensive repairs.

What Causes Wipers to Catch or Skip
When wipers don’t move smoothly, it’s usually not random. In most real-world cases, one of these issues is behind it.
- Loose wiper arms: This is one of the most common—and most ignored—causes. Even slightly loose mounting nuts can throw off the entire motion.
- Worn linkage: Over time, the linkage that connects the motor to the arms develops play. That’s when one wiper starts lagging or hitting the other.
- Blade condition: Old, hardened, or uneven blades don’t glide—they drag. That’s what causes skipping or that jerky movement across the glass.
- Incorrect installation: If the arms were removed and put back in the wrong position, they won’t park or sweep correctly.
- Motor timing issues: Less common, but if everything else checks out, the motor synchronization could be off.
Common Mistake: A lot of drivers jump straight to replacing the motor, when the issue is usually something simple like alignment or worn blades. That’s an easy way to spend money you didn’t need to.
What Actually Fixes the Problem
Don’t just start replacing parts—fix these in order. Most problems get solved in the first couple of steps.
- Start with alignment: If the arms aren’t positioned correctly, nothing else will fix the issue. Turn the wipers on and off, let them park, and check their resting position.
- Tighten the mounting nuts: If there’s any looseness at all, fix that first. A slightly loose arm can cause uneven movement and collisions.
- Check blade condition: If the rubber is cracked, stiff, or uneven, replace the blades. Trying to “clean” worn-out blades rarely works long-term.
- Clean the windshield and blades: Dirt and buildup increase friction more than most people expect, especially in dry or dusty conditions.
- Inspect linkage (if problem persists): If one wiper feels loose or moves differently, the linkage underneath may be worn and need replacement.
Real-World Insight: Most wiper problems aren’t caused by a single failure—they’re a combination of slightly worn parts and small misalignments. Fixing just one thing usually isn’t enough unless you start with alignment.
Quick Troubleshooting Steps
- Check blade size: Wrong-sized blades can hit each other or miss sections of the windshield.
- Test park position: Turn the wipers on and off and watch where they stop. If they sit too high, they were likely installed wrong.
- Feel for looseness: Gently move each arm by hand. If one feels noticeably looser, that’s your problem area.
- Listen while operating: Clicking or uneven sounds usually point to linkage wear, not just blades.
Key Takeaway: If your wipers are catching, fix it early. Most of the time it’s a simple adjustment—but if you ignore it, it can turn into a more expensive repair involving the linkage or motor.
If your wipers are still acting up after these fixes, it’s worth taking a closer look at related issues like blade quality or installation. You can also check this guide on choosing the right windshield wipers to avoid repeating the same problem.
Helpful Resources Worth Checking
Use these resources to verify safety information or double-check details before spending money.
How do I stop my wipers from skipping?
Start by cleaning the blades and windshield, then check alignment and blade condition. In most cases, skipping comes from worn blades or improper positioning—not the motor.
Why do my wipers hit each other?
This usually happens when the arms are misaligned or installed incorrectly. Resetting their position after letting them park typically fixes it.
Should I replace the wiper motor?
Only as a last step. Motor issues are much less common than alignment or blade problems, so check those first.
Can dirty glass cause wiper problems?
Yes. Dirt, oil, and residue increase friction, which can cause skipping or uneven movement—especially in dry conditions.
How often should wiper blades be replaced?
Every 6–12 months in most cases, but sooner if you notice streaking, skipping, or noise.
