all lights were working on my k10 until i put a new radio in the car, the only lights that work now are the headlights and indigators and the reversing lights, all the other lights ( sidelights,interior light,dash lights, rear brake lights ) arent working atal and have no clue whats going on and i dont know if its just a fuse or what but i have no manual to tell me where the fuse is located for these lights, just the headlight. so any help with this situation would be very helpfull at this stage as i dont know whats going on.
