ok here is my problem. when i drive at night, my lights dont turn on in my dash, i have to just about turn all the lights on in the truck to get them to light up. instead of getting them to turn on the wrong way, how could i fix it so when its dark out, they will light up like normal cause the knob to turn them higher or softer doesnt work its either all the way on or none at all. can any one help??? i'll try to explain it better if i need to.
