You may want to repost this at rec.autos.tech
alt.autos.gm is pretty much a dead group.

Could be the ambient light sensor on the dash.
Could be the headlight relay in the fuse box under the hood.
Could also be a blown fuse or as simple as the light bulbs failed.
Next up would be a broken ground wire.
Then possibly a bad BCM.


How about we start with a few tests first?

Are both high and low beams not working? On both sides?

Pull out the headlight switch to turn on the headlights. Do they come
on? If yes do both High/Low beams work?

If you pull the dimmer switch up all the way (like you're dimming the
lights) do the headlights come on?

If it is the BCM, it may be cheaper to buy a new car.

If your Buick is anything like my 2001, it will be falling apart soon
anyway. I gave mine away after 6 years.

Nah. That car is actually an easy bypass to drop the BCM out of headlamp
control. You just return to using the switch instead of the automatic
lights. You do lose DRLs but unless you're in Canada they are not
required anyway.
