When you say flicker, does that mean they go dim and bright or go completely out and come back on?

The headlights & dash lights are on, and just begin to flicker. They never go out , , , really weird.

Check all your grounds for corrosion. There are many body to frame black wires/cables. Even if they look good clean them as a first step. There are some underneath the frame also.
