Default Headlights wont open or turn on!!

Ok so they worked last night. I get up today and they wont open or turn on. Yes the taillights work and the parking lights. The fuses are fine, to both headlamp motors and low beams. Performed a hard reset with battery while assembly was manually up. Connected battery back and lights went down using motors but low beam never came on! Any suggestions?!?

There is a control module for the headlights under the passenger side headlight. Also check for codes.

How do you know the motors are working if the switch won't open them up ?

Also did you try flipping on you hi-beams to see if that helps or if they work ?

See if you getting power down to the control module. If not its you headlight switch. I had the exact same issue. Hi beams and eveything worked fine but they wouldn't pop up and low beams wouldn't go on.

I had one of my techs at my dealership working on it and he got to the module and got them to move by connecting and disconnecting that. They worked. But no low beams. High beams only. So the module moved them but the switch wont. I am going to swap out the switch this afternoon and see if that works.

My guess is the headlight switch failed. Search the internet they will be half the price of the dealership
