My sunroof just decided not to close. It will open, but not close. So I pulled out the manual and under practical hints it gave directions on what to do. Simple enough, I figured, even though I didn't have the toolkit, I decided to use a vicegrips and any sockets i could find that fit(16 or 17mm) Well the white plastic hex nut broke, and I got an ovalish shaped rod. I used the vicegrip on that and it doesn't move. Is there something I have to disconnect to disengage the power and switch it to manual? Thanks, M44
