I have a similar problem, but when I push the button, it pops up then makes a loud, grinding noise and stops. I'm afraid to push it in case it gets stuck OPEN. That wouldn't be good. My mechanic told me to take it to a body shop, so I did and they didn't know what to tell me. Any suggestions? I'm going to sell it in a month or so and want to get that taken care of, since I'm in Florida
