Dad check this out. I built this truck from top to bottom. i put in windows[
(that were hard) headliner and alot of things. This wiper motor was the hardiest thing i put in. And i'm still not right. I loosened the set screw on the motor arm. Moved it a little, i thought i had it. Now my passanger wiper goes all the way back. Fine The drivers side does half the window. What is wrong. I thought this thing was a perfect switch.
