Ok, so the 4x4 switch checked out fine but I also tested that yesterday. Tested it again to be safe. I tested the main light switch and it has no resistance value on the dimmer. Then I fiddled with it again and it did have a resistance value on the dimmer. I got fed up with it and threw it back in the truck, hooked everything back up and gave it whirl. I changed 4x4 modes and my backlight fuse didn't blow. Noticed an entirely knew problem, the headlights don't turn on. All the interior lights work, the dimmer works, the backlight for the instrument panel doesn't blow. So I gave the knob a turn and the parking lights work fine and putting it into auto mode turned on the parking lights. Then I gave the dash a couple of bangs and auto mode would no longer work and the defroster no longer worked. I am officially declaring this a problem of the main light switch. I won't have money to go buy one for a few days. I will update with the results at that point. Oh, I also check the junction box and battery distribution box fuses that control the headlights. They both checked out. I didn't check the bulbs. I guess I should do that. I still think it is the switch though. Too many problems right in that area.
