In the diagram for headlamps, the top wires are voltage for high beam and low beam. The bottom wire coming off the headlamps is ground, a constant ground. The headlamp switch appears to ground the low beam relay. Our database doesn't give good info for your headlamp operation, at least I couldn't find it.
If the turn and headlamps both work off the same multifunction switch, I'd have to check that when the problem is ongoing.
