The headlights on my '83 Mark VI come on as soon as I start the car and I can't turn them off...Vacuum failure or bad headlight switch?

make sure there is nothing covering the lamp sensor. Sounds like its blocked or bad though. If the switch was bad, it would have the lights on constantly.86 Lincoln Town Car (Galactica).

Turn the autolamp off on the outer dials and see if they go out. If not, switch.

yup... autolamp sensor is bad then probably (or the wires from it to the switch are buggered). If the relay was welded shut, it would keep the lights on no matter what you did, so that's apparently fine since the lights went out with the feature turned off... so that leaves the sensor and switch and related wiring.
