No low beam headlights
Trying to troubleshoot headlights, 1974.
My headlights will come up, and high beams work... just no low beams. Would both low beams go out at the same time? I wouldn't think so...
Are the high and low on separate fuses? I wouldn't think so, but just asking.
Also, the fuse box - there's nothing that blatantly says headlights... so which fuse runs them?
I know they worked, but the car was at a shop for 16 months not driven... now they don't work. Tail lights and turns work... as well as interior dash & dimmer on the instrument cluster.
Thanks in advance.

Easy to test the headlights on low by using battery. Sounds like perhaps dimmer switch? If you have a meter or test light you could unplug the low beam and using dimmer switch see if you are getting voltage at light socket

I had a similar problem on my 78. The low beams wouldn't come on. If I turned on the high beams the low beams would come on.
I changed the dimmer high beam switch but that wasn't it.
It turned out that the left low beam headlight connector had 1 wire that wouldn't seat on the bulb. Once I pushed that into connector to the bulb BOTH low beams started to work.

Yes... I only have the two side screws... missing all 4 top screws... ordering some now.
But the bezel is stuck.. the whole assembly needs to come up more in order to pull out... but reaching the adjustment screw is gonna be a challenge.
