Finally received my ‘05 roadster after the dealer spent a month trying to get the top to work -with no avail. I have gone thru the entire procedure as outlined by Pizzaguy here, with the following results:
1. When I depress the top down control the windows go down and there is a constant beeping, but nothing happens.
2. When I put the top down manually the top raises correctly when I press the button.
3. I have manually cycled the top up and down several times with no success.
4. I have pulled the no. 25 fuse for a few seconds with no success.

To me it appears that the problem is with either the Top Open Switch in the top of the windscreen, or the Cargo Divider Switch. The cargo switch seems to be working okay as it clicks but I cannot get access to the top open switch. Since I believe that these two switches are wired in series how do I troubleshoot to find which is bad? Then if it is the Top Open Switch how do I access it to repair/replace it?
Thank you for any help.
