Wiper Motor Operation

[340Challman]

The 3 speed, and probably the 2 speed wiper motors, just run in a continuous direction clockwise or counter clockwise whichever it is right? They don't oscillate do they? You can just adjust the running speed of the 3 speed motor correct? If that is the case, my linkage is never going to work without hitting the upper cowl when the motor rotates to the highest part of the arc. So, do they oscillate?

The operation is one full turn of the output shaft of the motor.

Ok, as I thought. Well has anyone else installed an AMD upper cowl and had linkage problems?

The motor goes round and round, but the linkage pivots back and forth.  Maybe post a video of the issue?

The linkage is attached to the motor by a lever arm. That then makes a circle. When the lever is at its highest point of travel in that circle, I have interference. Also when the lever is at its farthest point in the circle to the drivers side of the car, my linkage binds up.

So the motor and the pivots all mount to the upper cowl. If those dimensions are off, you're going to have problems. If the location of the motor is too close to the drivers side pivot, the motor is going to try to shove the linkage too far in relation to the pivot and will bind up.

That's my problem.
