I have a wierd sliding door on my 078 T&T Touring. Almost always, it the passenger side, I press the close button (any close button) and it starts to close then backs up.... and clicks over and over. The only way to close it is manually. It usually happens on a slight grade. any ideas? The tracks are clear as far as I can tell

 

I have a similar problem, anyone have any solution for this.

This is a 2010 T&C and under warranty for another 5k miles so I want it fixed. I'll start my own thread on this.
