My 2015 Equinox has no audio.
My 2015 Equinox has no audio. The dash display is working. Radio station and volume level displays but no sound. No sound when trying to use Bluetooth. No sound when using turn signals. Turn signals are working and display on dashboard but no sound. All dash lights come on and fan works. It is just the audio that is not working.
My 2014 did that after I had to have a jump start. It turned out to be one of the connectors above the battery became loose. All we had to do was just push it back into place.
