Hi folks,
I cleaned and re-assembled everything, and what happens is that when I tight the nut holding the wiper arm to the motor and start the motor, I can hear the impulse of the motor, but it is like the arm cannot move.
The motor works fine if I disconnect the arm.
I cannot understand what prevents the arm to make its movement, everything looks good, including the splines.
I wonder, it this supposed to have this play, or should it be pushed inside?
More images, the arm looks absolutely fine, but clearly, something mechanic happens when the arm is in place, preventing the natural movement it is supposed to make.
Thoughts?
Thank you!
Alessandro
