2008 town & country driver's side door node doesn't work.

Hello, the questions I would have is: what diagnostic testing has been done to confirm that this "node" is what is causing the battery to drain? Where did the "replacement node" come from? Is it new from Chrysler? Used? Do you have a diagnostic tool on hand in the event something requires programming upon replacement? Is it possible that the part you are speaking of may not be the actual problem, but maybe there's a wiring issue that's now been disturbed with replacement of the part -- causing no power at all, when before maybe it was shorted to power causing the draw? Lots of questions, and even though you are making efforts and trying hard to resolve this concern, you'll really need some resources like a wiring diagram and workshop manual and diagnostic tools to get through to the bottom of this concern.
