Ok, I bought a truck a few months ago. It is a 1993 Chevy Silverado. I don't know a whole lot about vehicles but it also has 1500 on the side of it and 4X4 on it too. After I got it the radio would just shut off after a few minutes of it being on and it did that for the next month or so. Today the radio wont come on or do anything. Does anyone have any insight as to what the problem could be? Could it be just a fuse or would it be something bigger like wiring?? Any help with this would be greatly appreciated!!
