I have a saab 93 convertible 2005
the problem is with the roof it would only just start to open then stop the same as when something to large is in the boot.
I removed the six nuts which hold the roof bag to the back of the seats in the boot .The roof now works fine.(I am a tech support engineer) so I deduce the problem is a micro switch which says when the boot has to big a bag in it.
the problem I have is where is the micro switch so I can adjust the gap.
