My 2001sonoma headlights are always on .when you turn the switch on the dash they do not get brighter.
headlight switch has a short in it and needs replacing This is very common on older ford trucks.
I would start with replacing the head light switch
More that likely the headlight switch is bad. Turn your headlights on and when they start to flicker tap on the headlight switch real fast. If they flicker to you tapping on the switch, that's the problem. They had problems with that switch around that year. It's a pretty cheap fix and you can do it your self quickly. Can also be a sign of a failing alternator.

Try replacing the headlight switch, it has the dimmer built into it.
On the back side of the headlight switch (behind dash) there is a little silver button Push this button and you will be able to pull know all the way out of switch-then unscrew bezel and remove switch from rear Ford suggests replacing connector at the same time
The headlight switch may be bad. Try replacing. Its the Headlight switch. The switch has a built in Circuit Breaker that self resets. It has become bad and will eventually give it up.
could be the the headlight switch, dimmer switch, headlight relay, or a problem with the wiring
