If you are able to, try to push the inside top of the slide while some one pushes the open switch. If you can move the top somewhat mere then what it has been opening then something is out of alignment, if it won't go out any more than something is stopping the top of the slide. As said above look at the slide roof when slide is mostly in to see if something is stuck to the back side of inside seal.
