one of three possible things.
This is weird. I think I have narrowed it down to one or all of three things. Ignition Switch (most likely candidate), loose ground wire, faulty computer!
When I go to turn the truck on in the second position the electronics turn on but the dash lights do as well!
Then if you have the ignition key out, and turn the lights on the electronics turn on and so does the lights and dash lights.
I replaced the headlight switch, dimmer switch, fuses, all recently.
What do you guys think? Truck starts fine. Runs fine.
