So i went to put my top down this AM and it wouldn't go. So i opened and closed the trunk since in the past it had been a sensor or something blocking it. Then when it was going down it made it 95% and stopped. it wouldn't go back up and made a terrible grinding noise when you tried to push it to go down. Just dropped it at the dealer and after paying $150 to diagnose they said it would be $750 to fix the part they "think" is causing the problem. They said the part is $400 and labor $300. I will try to get the part number from them today but they said something like it is the "Drive Lock, Switch, Bolt + cable, Conjunction, something or other" I think it is the top cover drive switch but will find out more. It seems expensive and excessive and maybe not even the problem. I asked the to put the top back up so I can think about it. Anyone have anything similar happen?
