I have a model 2014 Chevy Silverado single cab 4x4 and the drivers side window and passenger side have stopped working as well as the stereo stays on after the vehicle is shut off (opening door does not cancel the radio) I have replaced the window switch. I have also checked all fuses and they are good any ideas where to look next. I’ve took it to the dealer and they couldn’t find the problem
