Started my car up and have speaker noise/loud buzzing coming from speakers, even with radio off. And even with the car off and key out it would make buzzing noises for 10 or 15 minutes. The radio does not work. Radio lights up but does not play anything. It sure seems like I have a short some ware. I was looking to pull the fuses so I could stop the noises,seems like there is several fuses for the radio. Does anyone have any ideas to help with this issue ?
