how can I replace the door lock motor? on 2005 Dodge Grand Caravan

From doors lock and unlock with the lock button, the sliders do not. They used to of course, but now they don't. I'm not sure what I need to replace or how to do it.

Sorry for being so wooden headed, but are talking about the door panel on the drivers door? Thx.
