Wiper Help....

Frnknsteen said

Just trying to envision it in my mind, but the wiper motor should give you a set amount of throw as it goes around. Say 4" for the sake of argument. What I would do is put the wiper at the bottom of it's stroke, then move it to it's top location and see what location on the arm gives you the proper amount of sweep on 4" of movement. It might help to make a little paper protractor so you can simulate where the arm will be at the top and bottom of it's stroke. See below for a sketch of what I am trying to describe:

Don't know how the passenger side is driven... Does it have a tie rod that drives it off the driver side? I would think if there is, that they would have to tied at the same distance to get the same amount of movement.

The wiper motor turns in complete circles. I'll have to measure the distance on the motor lever but I believe it's close to 2". So it starts pointing towards the driver's side and goes counter clockwise. This it'll have roughly 4" of throw. Now I'm thinking that if the driver's side needs another 6" and that means moving the pivot point closer to the fixed pivot by roughly 1/2". I'll have to check and see what that gives me on the end of the wiper blade.

I believe that because the passenger side runs off the driver's side pivot point it'll remain unchanged unless I change the driver's side arm. So moving the driver's side movement pivot will be ok since it'll just turn the fixed pivot more however it'll leave the passenger side pivot and arm assembly unchanged.
