I have a 2006 roadster that until recently the top was working fine. Now when I release the top, the windows go down and I hear the motor working but the back of the top won’t release from the back top of the trunk. I also found a small white plastic piece in the trunk. I’ve taken it to two places already and no one can seem to help, including the Chrysler dealership. I love the car but I’m about at the point where I’m ready to get rid of it over this.
