The drivers side sliding door on my 07 T&C is stopping at the same spot, whether is opening or closing. The track is free of debris. What could be the problem here? it will work fine after of before this certain spot., which is about 9 inches from the fully closed position.

 

There's a plastic liner in the track. Sometimes it wrinkles or gets displaced. I had a similar problem with my Plymouth Voyager years ago. Look for movement of the liner as the door cycles.
