Maybe You Saw this problem on your Saab – wiper parked in vertical position when you turn off the car.
Matthew Brenengen created interesting DIY video in which he explains how to easily solve this problem without replacing the entire assembly.
In his case, This was the fourth time our wiper motor has stopped parking where it should (and the far right position).
The first two were fixed under warranty. The third time Matthew did what everyone else does, and replaced the motor. This time he figured out what was wrong and fixed it. It was just a corroded ground. Easy, easy fix for FREE:
Thanks to Matthew on behalf of Saab community on a detailed video DIY presentation.
