My Guages, radio, and headlights arent working. They only work if you flip the headlight switch all the way up and turn the brights on. (not the dimmer switch) or if the headlights are already on (they still come on at night automatically) i can get the guages and radio to work by switching the headlight switch all the way up. I checked all fuses they are all fine. The relays are fine too. My buddy and i had it working perfectly early because we found the bolts on the fuse box under the hood were loose so we tighten them down and then he started to hit the fuse box and it got everything to work fine. then laster on that day i was driving it and wanted to see if the dimmer switch (not headlight switch) was gonna work so i turned it all the way up, to turn the inside cab light on, then it made all the guages shut off again. and now the guages are only working if you turn the headlight switch on and turn the brights on or if its dark out and the automatic headlights are alread on and u flip the headlight switch up (not the dimmer switch) then the guages will work. Has anyone ever experienced this? or have any ideas? I replaced the whole headlight/dimmer switch unit with one from the junkyard and it didnt solve anything.
