You can get the replacement door switch by RPO code from 1aauto, partsgeek, and even amazon cheaper then what the dealer or who ever sold you that part. I have one that I believe is going out. Everything on the switch is functioning right now except one module that controls the memory for the seats, adjustable pedals, and the heated seat driver side. I do show power getting to the module that isnt working, but I still believe it is the window,lock,mirror module as that is where the other module connects to. I found that one on 1aauto, and parts geek for about 130 to 160. Hope this helps.
