Bad ground in headlight system

Hey all,

Headlights are not working on low beam, but high beams are dim. Checked the relay, dimmer switch, and all fuses and all are good. Pretty sure its a grounding issue at this point. does anyone have a diagram or know the locations of the grounds for the headlights so i can check/fix them? Can't seem to find any online

Many thanks!

Similar issue on my '02, but it affects the daytime running lights and those little corner bulbs above the headlights. Bulbs are good, but no light.

The DRL (high beams) are switched by relays to form a series circuit.

Sorry I do not have the electrical diagram.
