My dear old 86 ram has the 4 headlights, 2 low beams and 2 hi beams. My problem is when I pull the lever to go from lo beams to high it does illuminate all 4 beams but goes back to only lows as soon as I release the lever. I was thinking it might be a relay or something in the lever on the column but recently I had a couple days when it magically fixed itself and kept the hi beams on as it's supposed to. Anybody out there have any clues or insights? Can you point me in the right direction to continue troubleshooting this? Where does the hi beam/lo beam relay live in a Gen 1 truck and is it possible that it can fix itself for only a short spell like that? Thanks in advance ever body...
