When I trun on the head light switct the low beam and high beam light do not work.

the switch supplies power to the relays that switch on the lights according to the position you have it at
so on high beam there will be 2 high beam lights working
on low beam there will be 2 low beam lights working
back to passing lights or flashing head lights , both beams will work so the switch is the last item to consider
Now with only one side beam not working it comes back to the ground on that light for that bulb
remember that electricity follows the path of least resistance so it the ground is bad the current will ground out through another point including a light which will switch that light off or make it not work
remember the brakes light that flask when an indicator is used --same thing

Your running lights which come on when you are in drive should be the ones flashing when you use the key FOB to lock or unlock vehicle not your head lights. Although unusual maybe both low beam head lights are burnt out or a bad ground, that the only thing that makes sense to me.

To clarify, when you pull the turn signal lever towards you, the high beam lights will come on only as long as you hold the lever up. This is the flash to pass feature.
To switch the headlights from low beam to high beam, you push down on the lever towards the dash. Then the high beam lights and the blue indicator light should stay on.

First check, is there more than one headlight bulb, if so, the low beam bulb has failed, needs replacing.

If not you'll probably find that the head light bulb has a double filament, low and high beam. The low beam filament has failed. You have to replace the bulb.

I have the same problem and I've tried two fixes so far and neither has worked.
- I replaced the daytime running light module and that didn't work
- I replaced the trun signal/hazard/light switch and that didn's work

I've had one comment that it could be a ground issue.
hope this saves you spending money on "fixes" that don't solve the problem

Common problem, there is a headlight relay in the power distribution center under the hood that needs changed out.

Check for headlight relay and fuse. Some cars have separate circuits for head light flasher and normal high/low beam. From your description, I would suspect a bad connection to/from relay or relay itself.

possibly head lamp switch. daytime running lights on separate circuit and use the high beams at reduced voltage. does flash to pass work? that's high beams too. do high beams work?

Is it just low beams?
do taillights work?

You headlight lamp have a diffuser mechanism which allows it to flip between the hight beam and low beam feature of the bulb. In fact, you high beam will function even if the low beam is not working.

I would recommend the purchase of the new headlight lamp. It would cost you you any where from $15.00 per unit to get a replacement lamp

the head lights have tree wires goig to it one groun one gets power when high beams on the 3rd gets power only with low beam on test the wires or try by plugin a good known head light to conector if it works with low beam then replace both head ligts because head light come with two bulbs in one high and low
