My 1999 Boxster has had it's hardtop on all winter, and now that Spring has sprung and the sun is shining I naturally took it off.... and found a problem:
When the soft top is closed and the clamp fastened, the windows stay open a few inches and refuse to close. They will go fully down, but not fully up.
When the soft top is fully retracted (or the hard top is in place) the windows function correctly.
When the hard top is on and I undo the clamp, the windows drop a few inches correctly... so the microswitch above the rear view mirror seems to be working. I proved this by pressing it with my finger then trying to retract the soft top- the soft top stays put as it should.
So what is the cause of the problem? Is there more than one microswitch in the system (probably yes, there must be something that tells the soft top when it's reached the fully retracted position)? And / or is there some logic board controlling everything that's blown?
If I can't figure this out then I'll have to live with the hard top on all summer (and summers only last a few days in the UK so the situation is desperate!)
