CCONLEY

I have a 2015 GMC Sierra 1500 that has this issue. I just got done taking everything apart in the dash and took all the connections off of both grounds left and right twice. Cleaned everything up and trimmed the insulation twice. Reconnected everything and for the first 30 minutes everything worked like it should then bang everything started glitching and bouncing again. I don't know where to look or what to do at this point.
