Canyon GMC 2004. 5cyl crew cab. The dash light problems doesn't always happen. To me it seem like a loose connection somewhere? If I stop and kill the engine the dash lights may turn back on or the may not. The radio and it back-lights are also the radio is involved also the clock gets real dim. The truck has the auto headlights. Is there a sensor that might be dirty or a fuse. Just asking most probably out of my knowledge and will have to take it to the dealership.
