A fellow club member has a 2004 Boxster S with some top issues. All was working fine until last week, when the top would not retract/open. The 30A fuse is intact, and all pre-requirements to operate the top were followed. My guess is that it's the main switch, but I thought I'd post here to see if there is any common issue that has been found in these cases more often than other reasons.

Thanks!
