Purchased my first s10. Its a 2000 4.3 vortec, for whatever reason the radio will not power on. The clock is on, put it on power and nothing happens. I can press eject and hear the cd mechanisms working so i'm assuming the radio has power. It does not display that it is locked or anything of that nature. But when I hold 2 and 3 presets I cannot get it to give me a code, it gives me 3 --- dashes instead. holding 1 and 4 to be able to enter a security code works fine. I checked the radio fuse inside the door and looked over the fuses in the engine bay but I didn't see anything blown. any information is greatly appreciated! I don't mind replacing the radio just wanted to see if it was fixable prior.
