I have a 1990 Jeep Cherokee Laredo, and last night i went to go somewhere and had no head lights. I had all my marker lights, turn signals and brake lights, but no head lights and my fog lights wouldnt work also. SO i attempted to use my brights and my headlights came on, and only would stay on if i held the brights in place, as soon as i let go, they shut off. Anyone think they know my problem? or have had this problem.

-Thanks

 

I would say headlight switch.
