84 quad lights, pass low beam works only with high beam

[Bobby Pootz]

Hello,

I've tried to search but have found no answers, I swear I read it last year while looking at headlight threads.

The passenger side low beam light does not go on. It will only come on with the high beams on.

I've done nothing recently to change anything electrical, I also checked to be sure the ground was good and it was.

Any help would be great, I know it's not the bulb. Thanks in advance!
