What a waste of time and money. So what my whole window might have to be replaced? U can’t just remove the 2 arms and replace them?I'm in similar situation (2019 JL 2 door). Right support bar fell off back window and obviously window will not stay up with just one arm. I thought a quick trip to dealership would be easy, uh no. According to the dealership, the support arm cannot be reattached to the window, the entire window has to be replaced. OK, took it back once window was ordered and in stock, but it was clear window, not tinted like original. So, there will be a third visit to get it repaired once the tinted window arrives. We'll see if that visit goes as planned.
