Short demonstration on how to inexpensively replace the climate control buttons on a 2011 BMW E92.
Sorry for the shaky video. Did the work while recording on the massive iPhone 6S +. Thanks for looking!
Got to www.ebay.com and search for "(your car) climate control unit". For example "2011 M3 climate control unit"
Some of our bimmer friends have found these units on Ebay for only $5!
