hazard light issue....?
Recently bought what I've been told is a 1976 F100, but appears to have some 1978/79 items. I have a weird issue: the turn signals in the rear work fine, as do the parking lights and brake lights. All bulbs look good, nothing blown. When I turn on the hazard lights, only the rear passenger light activates. Everything else is dead. What in the world would cause that?

first thing I did was check the bulbs, they are all good. Next thing was to replace both flashers. When I turn on the left turn signal, the left light blinks correctly. When I turn on the right turn signal, the right light blinks correctly. When I apply the brakes, the brake lights come on correctly. When I turn on the parking lights, the rear parking lamps work properly. When I turn on the hazards, the only light that comes on / does anything is the passenger rear, and it flashes. No other light on the truck comes on or flashes when the hazards are on.

Did you check the corrosion on all bulbs in question? I would invest in a bottle of contact cleaner DeOxit is a good one.

yep, checked that, checked the grounds, etc. They all work except when I put on the flashers. I wonder if the flasher switch is going bad, or if the column wiring is messed up (getting the impression that this truck is a hodge-podge of years)
