Zipoteloco Posted December 23, 2014 Share Posted December 23, 2014 New here, I have a 2014 Sierra crew cab SLT with bose system. Couple days ago after installing a sub, every time i turn the ingnition swith to the on position, the horn honks around 3 times rapidly, the truck starts and warnig lights on the dash. I tried disconnecting all the power to the after market amp but it still doing it. Anyone has any idea why is doing this? Quote Link to comment Share on other sites More sharing options...

ZakAttack Posted December 7, 2019 Share Posted December 7, 2019 Z, I have this problem now in my (new to me/used)2015 3500 Denali HD. I can’t figure it out and it’s driving me nuts. I leave for work early and the triple horn beep is annoying to sleeping kids and neighbors. Any help would be appreciated ! Quote Link to comment Share on other sites More sharing options...
