only thing I can think of is the wiring is ****ed up somewhere.

check voltage at the wires.

Also, get a service manual, itle show you what voltage your suposed to be getting.

lots of people have the headlight not going down problem, but no one has reported back how they fixed it. the online factory service manual is in my signature. there are lots of electrical diagrams showing how the headlights work, but it is complex.

The headlights have their own timer called "headlight timer".
