Hi, I have a 2000 suburban 1500 4X4 with a sunroof. it is partially stuck in the vented position. the passengers side is vented and stuck in place. the drivers side moves both ways when switch is pressed either way, to the point it twists the glass as passengers side is solid. Any ideas? (truck was unused for almost 2 years sitting in a yard, sunroof vented the whole time, battery died and had to be jump started as well) Other than playing with the switch, the only other thing I tried was to spray WD40 on the track.
thanks.
Jim.
