Check your headlight wires for continuity to ground. The one that reads closed is the ground.

Black wire is the Ground on 2001 headlights
Left and right do not share a ground

Both should be grounded on the Rad support however, and there should be a ground wire from battery to Rad support.

So passenger side is dimmer than drivers side in low and high beam, which it would be if it was a ground issue
And passenger side is not just pointed lower, i.e. out of adjustment?

They are adjusted correctly, and yes it's dim on both low and high beam.
