2002 ford focus sunroof not working correctly

The sunroof in the car is not working, the tilt switch is doing all the movements, open, close, tilt open and tilt close, but only if you keep it pressed. The open button does not do anytihing anymore.

Has anyone experienced this before? and if so what can i do to fix it.
cheers

I am having awful problems with the electrics of my 2004 focus. Electric windows only working intermittently and cigarette sockets have no power. Am hoping it's just a fuse or two
