Subaru Problems? Ask a Mechanic for Answers ASAP
This usually means the nut that holds the wiper arm on is not tight enough. If you pop the plastic cover up you should be able to access the nut. I believe it's 10mm, tighten the nut and then retry the wiper. This should solve the issue if the motor is working.
Please give it a try and let me know.
Sounds good Susan, I am thinking it's likely the wiper froze to the window after the car was washed. Of course I don't know where you live, but if it's cold and you turned the wiper on, it can actually happen. I also sent you a diagram to help.
Thought I would check in and see how you made out with this?
