The reason I mentioned the autolamps is because it supplies the ground for the headlamp relay. If for some reason the autolamp module was faulty, it could supply the ground circuit for the relay, even though the ignition was not on.
I'm going by the wiring diagrams for a 98 but they should be the same. The power for the auto lamps is taken from fuse 36 of the Interior fuse panel.
The headlamp relay is located in the relay module in the lower center of the dash. In the neighbor hood of beneath the radio. Fuse 11 of the power distribution box(under the hood) feeds the coil of the headlamp relay. The ground for the relay as mentioned above is supplied by the auto lamp sensor and or the RAP module during an alarm condition. Fuse 12 of the power distribution box supplies the 12 volts through the headlamp relay, when the coil is pulled in, to the headlights and park lights.
To test the relay, pull fuse 12 and see if problem goes away. If it does, then your relay is staying pulled in. At this point I'd try a new relay. post back with your results and we'll go from there.
