2004 Grand Caravan sliding door

2004 Dodge Grand Caravan The driver's side automatic sliding door is acting up. When the button is pushed to open the door, it opens but then stops after moving 5 inches. If the door is fully open and the button is pushed, it closes but then stops when it is 10 inches from being fully closed. The door opens and closes smoothly by hand just fine with no binding. The track is clear of foreign objects. I have disconnected and reconnected the negative battery terminal to ensure a full reset of the system. Thanks.
