I ended up taking my Acadia to the dealer and they did a "reset" for about $100 and everything works just fine now.Thanks for posting this. I have a 2013 GMC Acadia that has been having this issue for awhile. Same thing: the buttons dont seem to respond or they just go whacky and 1 press changes them 3 times. I am going to order this. I tried looking for it once with DIC as the search. No luck. But looking for GMC 2013 Acadia hazzard assembly seems to give me some hits. If you could tell us what part/where you ordered that'd be great.
