Some vehicles may exhibit a condition where
the windshield wiper blades chatter or wipe unevenly. Several different conditions
can cause wiper blade chatter. To completely repair wiper blade chatter, all
or following should be checked and repaired as necessary:
• | The windshield glass must be clean. |
• | The wiper blade element must be clean. |
• | The wiper arm tip pressure must be within specification. |
• | The wiper blade element set must be within specification. |
Windshield Glass Cleaning
Clean the windshield glass with windshield cleaner. The cleaner used
should be one that will not harm the paint finish or scratch the glass. The
windshield glass is clean when water no longer beads, but sheets across the
entire glass surface.
Wiper Blade Element Cleaning
- Lift the wiper blade assemblies off of the windshield glass.
- Clean the wiper blade element with a clean cloth saturated with
full strength washer solution.
- Rinse the wiper blade assemblies with water.
- Place the wiper blade assemblies back onto the windshield glass.
Wiper Blade Element Set Inspection
- Remove the wiper blade
assemblies form the wiper arms. Refer to
Windshield Wiper Blade Replacement
- Look down the length of the blade element. The rubber element
(2) that makes contact with the glass must be on the center line of the blade
assembly ± 15 degrees (1).
- Replace the element if necessary.
