Wiper Blade: Service and Repair

NOTE:
Possible causes of wiper blade chatter:
- Scratched windshield
- Rubber part of wiper blade is out of the frame or torn
- Windshield wiper arms/blades are loose or bent
- Wiper blades are waxy or buckled


If none of these causes apply to the problem, then the angle of the wiper arms to the windshield must be checked and if necessary adjusted before replacing the wiper blades.
