Question about 1992 Buick LeSabre
There is no relay.... there is a "Lighting Control Module". Its above the fuse box. Its hard to tell you what to check, without a wiring diagram, but if you disconnect the headlight switch and they go out, I would guess that the switch is bad, if you disconnect the switch and the lights stay on, then I would say the module is bad. But I would get a wiring diagram and check fully before spending any money on a module.
