1980 Monte Carlo headlight issue

[John1980Monte]

So now I noticed on my 1980 Monte Carlo I have a headlight issue. I have the four light setup. On the one setting both outter headlights come on. When I hit the dimmer switch both headlights on drivers side light up but on the passenger side only the inside headlight turns on. And for some reason the passenger side marker light is off, but when I go to signal left and right the turn signals work. Any help would greatly be appreciated. Thanks in advance guys

The most famous suggestion, check the grounds on the rad support. Then check to ensure the plugs have the right color wire in the correct plug cavity.

on the passenger side the high beam is burnt out on the hi/lo beam

I forgot to mention, I cleaned up the ground wires on the support, thought that would have solved it but it didn't. Ok thanks on suggestions guys. I will replace the bulb and update. Any suggestions on the marker light?

before you replace the light check with a test light to make sure the hi beam wire has power

I know it's a silly question, I don't have the high beam indicator light on the dash. Do was wondering what lights in the front should be on while switching high to low beam? Thank you in advance

the two outside light are hi/lo, the inside lights are hi only. On low beam only the two outside lights are on
