Question about Cars & Trucks
If you have a 740 with an electric sunroof, when the roof is in the fully closed position you should be able to push the closed switch again and have the rear of the roof pop up to the 'vent' position. If you have a manual roof, after it reaches the closed position you feel a bit of resistance; you then continue moving the crank in the closed direction and the rear of the roof should pop up to the 'vent' position.
If your roof does not move at all, you must NOT pry up the rear edge manually as there are cast tracks at the rear of the panel that hold it in place and you will break, bend, or damage the tracks, roof or the panel.
Most likely it is out of alignment and too tight for the minimal leverage applied by the motor to move it, as well as being thoroughly gunked up. The secret to lack of motion is most likely binding in the up and down motion of the panel. If manual, try moving the crank back and forth, bearing in mind that the first motion the roof makes is that up and down motion at the rear of the panel. If there is resistance to the crank motion immediately, there is 'likely' to not be any damage in the screw mechanism, just binding of the panel in the roof.
If nothing moves as you move the crank towards 'vent', push up gently through that small rectangular opening inside the headliner on the rear of the panel to help it along, by just pushing it free of the roof. The tracks at the rear of the panel move the panel up and down, either to pull it down before retracting or to pop the rear of the panel up for the 'vent' position, and if they are damaged or too gunked up, they will resist opening. The device that is connected to the motor/crank via screw cables slides back and forth in these tracks, raising and lowering the panel, which will not be possible unless you can move the crank/motor. Try to get it high enough to be able to peer inside the roof from the outside to unhook the headliner clips - once you get those, all is revealed and you will be able to see why your roof is not functioning properly.

SOURCE: sunroof will not close
When you press the button do you hear any noise coming from the sunroof? If not and you say you check the fuses then more the likely the motor burned out and you will have to replace it. But if you hear noise coming from the sunroof it may be that the sunroof came off track or is simply jammed for some reason.

a solution that i had is that if you can open your sunroof without it opening ur shade try that then fold the shade by pushing between or in the middle of it and popout the shade. this works but try not to push to hard or you can break the plastic runners on the side of the shade. check to see if nothing is in the way of the runners. then put back the back part first then slide it all the way to the back then, do the other part and clip them back together (there might be a little metal piece that pushes your shades back so check that first to see if its there first)

Definitely, you'll have to take a look to see if any obstruction is visible. To check the fuses first you'll need to find them. The fuse block cover should illustrate what each fuse is for. You can visibly check the fuses, with a flashlight. Just take a look at the sunroof fuse and check that its not burned. That the metal inside goes from one side to the other and its not burned or broken. You can use a test light or a multimeter, a test-light will do. I usually check them visibly, its obvious when you have a blown fuse just by looking at it. Its better just to pull out the suspected fuse to check it.

It sounds like it just needs to be reinitialized. Turn your key to the on position with motor off and hold the up/full vent button down for at least 30 seconds or until your sunroof either clicks or goes to the full vent position. That should fix your problem.

try this first (cheapest remedy first) open the sunroof fully take key out of ignition shut all doors then put the key in drivers door and hold key over 30 secs to unlock car(windows will go down)then wait 30 secs.then put key back in drivers door and hold key over 30 secs to lock car,windows will go up and the sunroof will close.if the sunroof does not shut properly then we start with motor park switch.....
