- Lifting or Skipping: When your wiper blades lose contact with the windshield and start to lift or skip, it’s often because they are worn or the spring tension has ослаблевать. Replacement is advised.
- Frozen Blades: In cold climates, wiper blades can freeze to the windshield, damaging the rubber. If this occurs, wait until the ice thaws before attempting to operate your wipers.
- Worn or Loose Frame: The metal frame of your wiper blades can weaken over time. Check for rust, corrosion, or loose bolts, and replace the blades if necessary.
- Damage from Obstacles: If your wiper blades encounter obstacles like tree branches or debris, they can become damaged. Inspect them carefully after such incidents.
- Harsh Weather Conditions: Extreme heat, cold, or UV exposure can accelerate the deterioration of wiper blades. Regular maintenance is crucial in such conditions.
