My 1995 Ranger Rover has developed a new ailment. It seems that when you want to pop up the sunroof, only the left side lifts up, while the right side doesn't do anything. If you slide the sunroof back, it will do so without any problem, but, on sliding it all the way forward, the left side lifts up a bit to seal with the body, but the right side does not, leaving a gap between the metal and the sunroof. Then the display indicates "sunroof not set". I have tried setting it several times, but the message goes away only for a few minutes, then the message pops up again. Then the sunroof did not respond when pressing the slide-back button, but it will (left side only) when pressing the lift-up button. Any ideas? I don't see anything that could be blocking it or anything like that.

On another note, my MPG hovers around 11, not anywhere near what other threads indicate, everything seems fine as far as I can tell (fluids, sound, engine doesn't seem "forced", RPM, etc.). Any suggestions?
