2005 Trailblazer Head lights

The headlights on my Trailblazer just stopped working. I've replaced all of the lamps and checked the fuses. I'm puzzled.

Probably need to track down the headlight relay; it may be dead.

what TG said, or the switch on steering column.
headlights as in completely, or only DRLs? you likely have DRLs and then headlights, as far as know GM lights philosophy.

Oh, yeah, can't run that much juice without a relay; the headlights are a big power draw.

And I think, most likely you had switch in dashboard, not on steering coulmn, which can over ride automatic features, but it's irrelevant now. Good you got it fixed.

And here's a twist from the good old days. Some cars had a built in circuit breaker IN the light switch. This was back in the day when the light switch was a pull/push knob in the instrument panel. If it tripped, you reset it by pushing the knob in (off) and then pulling back out to regain lights.
