After a carwash a couple days ago my radio went out, came back on for a second, and has been out since, I thought maybe a little water got in my door and shorted a speaker so it went into protection mode but it's been super hot here so I think if any water got in there it would be evaporated but it's still not turning on, neither accessory or constant wires have power at the back unless I'm testing it wrong, but the ground wire is good, I also checked fuses 14, 28, and 47, they were all good with the multimeter. I'm not sure if this is related but my ecu also has started testing every time I turn the car off. Any thoughts on this are very appreciated
