cunfused headlights

Been working on vehicles since the 70's finally came on something that has me stumped. Pulled old 2000 ram out of barn for son to use and seem to have head light issue. Started out as low beam light driver side would not come on, tested and replaced all fuses, looked for any obvious corrosion or broken lines and found none. Also checked wiring in steering column and found no issues. Move around cable harness to see if this would a reaction. NOPE. Just out of curiosity turned lights on and pulled fuse for right side headlights out. WTF. All of a sudden all four lights came on including right side which has no fuse in holder. Before this tested line for left side low beam and had no reading on meter and the continuity tester showed nothing. Bulb in tester is working tested it on right side lights and battery. Also checked light switch. Wire for low beam is violet with white tracer line. I am stumped folks any ideas would be appreciated.

As a general rule, when something acts goofy like this, I look at all of the grounds. Make sure every ground in the headlight circuit is good. Start at each light and work back.Just my 2 cents. Good luck

Sounds like a patchy ground connection. Double check the wiring. I it's simple to do and I think that's your most likely culprit.
