Hey Jeepers, when my rear window wiper is going down I hear a click and then a spring noise. It’s not hitting anything and it’s probably not cycled 100 times yet. It’s maybe coming from where the arm is attached to the bolt from the inside or it might be coming from inside the box. Any idea? I’d rather take care of it myself than go to the dealership, even though I’m under warranty. Any help would be much appreciated.
