Early Bronco

My drivers side headlight DRL’s will light up but not the round headlight portion. I’ve tried turning on the headlight manually from inside, unplugging the battery for about 10 mins, checked fuses, etc. The only time I can get it to pop on for maybe 2 seconds is when I unplug the wiring harness and plug it back in(see video). Otherwise, nothing. The passengers side works perfectly fine. I thought maybe it could be the headlight module? Anyone have any ideas?
