I recently had my heater core replaced so the whole dash of my TJ had to come out. After I got it back, whenever I turn my lights on, my gauges fall, the backlight for my gauges goes off, and the turn signal lights and high beam light come on. If I turn my lights off, everything works again. Also, when the lights are on, the light that shines in the driver's side floor comes on.
It is definitely more than just the standard Jeep problem of the gauges falling. I have had that problem in the past, and I already tried fixing it that way.
Does anybody have any ideals at all of where to look or what the problem might be? I would appreciate any ideals at all.
