When I pull the knob on the dash out all the way, the parking lights, tail lights and everything work fine, but I have no lo beams. When I click the lever on the steering column back the hi-beams come on, but if I click it again no lo-beams. I haven't tested the bulbs themselves, as both lights went out simultaneously I'm inclined to believe it's the switch on the steering column. Do I have to pull the steering wheel off to fix this? If so, where can I get one? If it's going to be time-consuming the truck isn't worth taking to a mechanic to get it done. It's beat up and I don't want to invest too much money into it. Any and all suggestions greatly appreciated! Thanks!
