So, I am continuing to work on my 1971 GMC project.
The hi beams dont work.
It is a GMC and when I push the hi beam floor switch (which is brand new) I get no headlights with one push and the inside two headlights when I push it again.
The GMC has 4 headlights so I think two inside ones are low beam and all four would be hi beam but not sure.
Harnesses to the new headlight lamps look fine (someone else put them in), I replaced the floor hi beam switch with no luck.
I dont see a fuse for headlights at all. Dash headlight knob works fine. Can’t seem to get the power to all four of the headlights.
I am stumped.
Any Ideas???????
