Symptoms
- Wipers streak or leave a haze on the windshield
- Wipers skip or chatter across the glass
- No memory of the last time blades were replaced
Likely causes
- CommonRubber edge worn or hardened from UV exposureSun exposure dries out and cracks the rubber edge over time, even with light use.
- CommonDebris stuck to the blade edgeDirt or grit on the blade can cause streaking that looks like a worn blade but just needs cleaning.
- Less commonBent wiper arm or frameA bent arm changes the pressure angle on the glass and prevents even contact.
What to do
- Inspect the rubber edge of each blade for cracking, tearing, or a rounded/worn edge instead of a sharp one.
- Wipe the blade edge with a cloth and rubbing alcohol first; sometimes streaking is just debris rather than a worn blade.
- If streaking continues after cleaning, or the rubber looks visibly worn, replace both blades (front) as a pair.
- Measure your wiper size or check your manual/vehicle database at the parts store to get the correct length.
- Lift the wiper arm carefully, release the small tab or clip holding the old blade, and snap on the new one.
- Test with washer fluid on a dry windshield to confirm even, streak-free wiping before driving in rain.
