How old are the wiper blades?
A recently put them on last week.
That when this started? More info will help!! Lift the wiper arms to the upright position to see if it stops.
well the other day but it was really bad today and the whole wiper came off
Let a mechanic fix this!! It can damage the glass!!!
okay I believe maybe it was put on incorrectly.. what do you think ? the blade came off that what I meant to say
