I have a 2007 convertible. I stored it last year over the winter and when I went to put the top down this summer it wouldn't move. It unlatches from the front window and lifts an inch and the trunk unlatches but the trunk wont move up to let the top go down. I've tried manually moving the trunk but it only lets me move it so far before it stops moving and it still needs to open more. I'm stuck on what is wrong.
