Help required – how do you manually close a Saab 900 sunroof?

The headline to the story says it all, really….

I’m in need of help and I’ve googled everything I know.
I have a 1993 Saab 900 Turbo (2dr) and can not get the sunroof to close. I’m trying to figure out how to manually close it until I can take a look at the switch.
I’ve read something about a closing the sunroof manually from the trunk???
Thank you for your help in Anchorage.

I know there’ll be a manual winder somewhere, but I never needed to access mine so I never looked it up.
Classic 900 owners – your assistance please……
