Hello, my stereo all of a sudden didn't work one day when I got in my van. I checked the fuse box inside the vehicle and found the audio/mirrors fuse but it was fine. Tested the wire harness and I'm getting power from the 12v acc wire but not the constant 12v wire. The diagram for fuse box under the hood doesn't have anything obvious to check. Anyone know if there is a fuse for the constant 12v ? Or any other advice on what to check. Im stumped. It's a 2017 SV thanks.
