Also pre 2016. They changed the switch in 2016 so the lever stays in either the up or down position so pressing the lever when it's already up or down won't accomplish anything. Pre 2016 models had the lever go back to the neutral position after it was activated. Hated that!!
Just wondering if a dealer can/will do any of this reprogramming, such as the flasher change, adding the temperature to the right cluster 7 I believe I even read about adding climate control to there as well. To me, I would be hesitant to try this at home!
