For unknown reasons, the car has no power (can not be jumped, or charged with a battery charger) and the sunroof is open, and its going to rain sometime today. I need to get this sunroof closed..does anybody know how to manually close the sunroof?

Any tips appreciated. I can always put a tarp over it, I suppose. Then I can get some used appliances and an old sofa and stick them out in my front yard to complete the picture.
