I just bought a 94' chevy k1500 4x4 with a new(45k on motor) 6.5TD, well the cargo light didn't work the guy said, so i thought to myself alright i'll check that out, i unscrew the screws to the housing for it and start to pull the 2nd lighting fixture out of its place and i hear a pop from the front of the truck then the far left light started smoking for a second or 2, so i didn't think anything of it..well i get inside my truck, all the gauges light up now BUT there is no power to the radio or the equalizer, the a/c controls and all that works, but no radio, no equalizer and no dome or floor lights..i checked the fuses and all were there and intact? what else could of went wrong?Thanks in advance..
