Check for voltage to and from the headlamp switch. Got to start somewhere. Did you check for voltage to the applicable fuses? Use a voltage tester.

My wiring for your model year isn't the best, as far as headlamps. Click on the link.
As far as a battery drain. You pull/replace fuses one at a time till the drain goes away. When you pull the fuse on the problem circuit, the drain goes away.
