As the title says, but it will move from where it stops to completely open, then back to where it stops. It stops just right before it stops sliding and makes the transition to go down. Ive looked for obstructions and even greased up all the channels. I have not seen any broken plastic pieces or anything. I need this fixed asap, heck... I know we dont have rain in the forecast, but with my luck and this sunroof open....it will come a flood!!! Thanks in advance guys!!!
