Beer Belly Posted August 25, 2020 Posted August 25, 2020 My 2015 Sierra was throwing Trailer Brake System warnings, so I dropped it at the dealership for diagnoses and came up with a bad Controller. I ordered a new one from Rock Auto and will be swapping it out myself. Any tips, tricks or tutorals appreciated.....looks simple enough, just want to make sure I don't break something from one of those hidden screws. Thanks in advance.
sierra015 Posted August 26, 2020 Posted August 26, 2020 Several good videos on You Tube showing this repair, it’s not difficult. Good luck,

Good luck, Thanks. I did try a search on you tube and couldn't find a video on the '15 Sierra, or anything that looked like my Dash. I'm sure it's an easy swap. Dealer wanted $230+ to replace it, I bought the part for $40 to my door, just don't want to miss something and break a panel. Edited August 28, 2020 by Beer Belly
