It's very likely that your Lighting Control Module is failing. I've seen several fail in our Patrol cars although they are Crown Victorias. Same car with a little different equipment. All of you lights are controlled by this module. It's a black box usually mounted under the dash above the gas pedal (although your vehicle is a little older than the cars I regularly service and I could be mistaken.) They are not cheap if purchased new. If you need to, try a reputable Auto Dismantler.
