Why are my headlights, dash lights,fog lights flickering intermittantly, and wipers working themselves intermittantly?

SOURCE: Headlights dont work

sounds like the contacts in the headlight switch have gone bad.. the switch needs to be replaced - I have seen this more than once...usually due to someone installing "high performance" headlight bulbs that pull additional current causing the light switch to "fry" over time.
first do yourself a favor, and test the bulb from one headlight, just to make sure the bulbs arent both burned out.

Try your headlight switch. If it is going bad it should affect all of these since they all work of the same switch.

where is the dome light bulb located?

take to a dealership because it sounds like a problem in the security system and take both remotes so they can reprogram them to the truck

SOURCE: lights flickering, horn honking, wipers moving while driving

Sounds like a bad body control module. Take it to the dealer to have them check and confirm.
