back windows dont work. If you put them down they dont come back up. Is this a recall that is covered?
Window would not roll up. Mechanic removed door panel and had to order new window regulator. Estimated cost for parts and labor: $300.00
I heard a pop in the window regulator which bust the window on the driver's side. It sounded like someone had hit the window with a baseball bat. Immediately I could hear glass fall within the door and then the window slowly started to slide down.
Replaced Convenience Module in trunk with a used part procured online for $150. Resynchronized windows. Works perfectly.
