i have a 2000 f250 4x4..my headlights and dash lights went out last night ..they will come back on from time to time but not for long .and some times not both dash and headlights at the sametime . any ideas
Check all your grounds pertaining to the headlight harness and make sure all connections are clean, tight and free of corrosion. If everything seems ok there then I'd consider the headlight switch itself to be bad.
