Windshield Wiper Adjustment?
Is it possible to adjust the arc through which the windshield wiper arms swing?
Here's a scary one that I have never heard of and which I hope is fixable.
Recently I was eastbound on I-10 in my new-to-me 07 Dutch Star when I ran into a bit of rain. No problem, I thought. I turned on the intermittent wipers, and then went to the constant wiper setting as the rainfall increased, and eventually went to high speed wipers as the rain came down in a flood. The wipers, in intermittent mode veiewed rom the driver's seat, move about a 90 degree arc from approximately a 3 o'clock rest position to a 12 o'clock maximum. In constant low-speed mode, the arc is about 95 degrees, from 3 o'clock to 11:30. In high speed, the arc is over 120 degrees from 3 o'clock to 10 o'clock. Due to the curvature of the windshield, the high speed mode arc puts half the wiper blade off the left edge of the windshield. On two occasions during the rainstorm, the wiper went way over to the left and stuck, hung up on the curvature of the windshield by the friction of the contact of the wiper blade arm against the glass. I had to pull over to the shoulder to manually lift the blade arm to restore normal wiping action.
I presume the momentum of the wiper arm in the high speed mode swings and twists the arm so that it can move around the curvature of the windshield. Is it possible to adjust the arc through which the arm swings?
