19 Sierra Denali Infotainment Issue

Recommended Posts

Hello, I have been having a problem the last couple weeks where when I use the volume knob on the dash it glitches the system to turn off and on the screen while also cutting the source music etc when turning the knob. If I use the volume controls on the steering wheel everything is fine.  

I have tried pulling the infotainment fuses on the right side block, and disconnecting the battery in trying to reset it. I have also reset all to factory settings to no avail. 

Any help is appreciated. Thanks.

From my couch the first thing I would recommend is try swapping out the knob.  It's merely a switch, and it's possible it could be malfunctioning.
