Windshield wiper blade chatter and skipping of blade across windshield can be caused by incorrect wiper arm angle.
The incorrect wiper arm angle will not allow the wiper blade to flip and follow the wiper arm.
It is most noticeable on the downward stroke of the wiper.
To adjust wiper arm,
-
hold wiper arm with duckbill pliers at A
-
bend wiper blade arm at B to obtain correct wiper blade angle
Angle of blade to windshield
Wax and dirt build up on windshield wiper blades can cause streaking and smearing on windshield when using wipers.
-
do not replace windshield blades that may only need to be cleaned
-
clean wax and dirt build up from wiper blades and entire windshield with alcohol based cleaning solution or rubbing alcohol and water
