What is the voltage on the power side and the ohms reading on the ground side, tested at the light bulb connector. Almost definitely sounds like a ground. Check ground resistance straight to the battery.

The ground behind the driver side front bumper to the frame. Two wires on one 10mm bolt right by the frame horn. I chased mine for a year and found it loose. Same lighting issue.
