996 Cabrio roof troubles. PIWIS "end position not reached" error

[dcapper]

I was out for a drive. It started to rain and my roof wouldn't go up. I had to manually put it up. When I got home I found the parking brake switch faulty. I replaced it and checked the fluid. The fluid was low so I topped it up. I tried to use the switches on the dash and the gear above me tries to move a little but that's all. If I extend the latch out and then hit the button it will fully close. But it still won't open. I hooked up my PIWIS to calibrate and I'm getting Function inactive, end position not reached. I metered the 3 micro switches in the latch and they are all testing fine. Any ideas what to do next?

I posted long ago about a piece of the clamshell drive that is likely your issue. Final microswitch is OK but not being pressed. Check my old posts.
