At the second I saw your comment, I went to the car and tried again. It still doesn't work and seems like the dimmer rheostat is bad or unplugged. I want to fix this, is this expensive? Or I can repair by myself?

Do you see the headlight indicator light come on on the cluster?

For checking the rheostat you can open and remove the little storage cubby on the lower left of the dash. Once you do that you can reach in and verify that the connector is plugged in.

Yes, I can see headlight indicator light when I opened the headlight on night. Does this mean something?

It means that the signal is being fed to the dimmer to tell it to go into night mode.

That the problem is with the rheostat or its wiring.
