Trailblazer headlamps

My headlamps aren’t working.
All other lights work.
All fuses check out ok.

What year model?

Have both high and low beams failed?

Are you aware of when they failed or did you flip the switch and get no results?

With the light switch turned on flip the dimmer switch to see if the high beam indicator in the dash is illuminated.

Pull the dimmer lever back to see if “flash to pass” functions.

And have you tried changing the bulbs?
