Anyone have a fix to close sunroof from UP position? There seems to be something broken as it will not go down and pressure will not force it down. It's as if there's something that locks it in the up position that is not disengaging.

I have searched sunroof issues, however, I did not come across this particular problem.

Motor seems to be fine and something does retract when I push switch backwards, but, it appears that there is something not connected as I can hear internals sliding backwards and forwards while roof remains popped up.

Best regards,

Patrick
