Headlamps on a 2004 Chevy Impala don't work

My headlamps on my 2004 Chevy Impala just suddenly stopped working. Do you have some ideas on what might be wrong?

Possibility the bulbs need replacement.

Check the fuses both in the instrument panel and underhood.

If blown, you’ll have to find out why.

It’s possible you have a faulty headlamp switch.

Also, check for poor ground/power connections.
