1998 venture sliding door schematic

Does anyone know where I can find a schematic for 1998 chevy venture back driver side door? I'm trying to get a part name or part number for the middle rollers to keep the door on the track.
Thanks

Why not phone a dealership PARTS guy and ask him. I doubt a schematic will tell you any other name than 'roller'. I know my Haynes doesn't say anything.

What is the door doing or not doing?
