Blind Spot Module bad on one side need replacement.

What is your question?

I have tested both blind spot modules on each side and have narrowed it down to one of the modules being bad and need to find a replacement part but having a hard doing so for the 2012 Chrysler Town and Country. The part number is 56038942AA. Searching online they want like $800-900 for this part. Is this universal? For example, can I use one from a 2013 T&C? The ones for a T&C 2013-2016 are way cheaper ($300-400) than the one for a T&C 2012.
