Both headlights out.

First check fuses,9, 28, 10, 52, with a test light. If ok then check low beam relay for power.If ok get back to me

See the guides below on testing wiring and relays

Attached below is the wiring diagrams for your headlights

I am giving you the wiring diagram for the exterior light system which includes the headlights.
If you look at the power wire that is on the side of the relay that would not be hot until the relay is tripped you can see that the day runner lights, DRL, and the low beams share the same power wire. It may have come loose somewhere and that could happen before the fuses are reached, so it would not blow the fuses and it would have to be loose after the node where the hot lines come off of the relays and share a wire until they split into seperate nodes for each. The color is on the diagram and the wire would be a heavy gauge.
Besides the coincidence of both relays failing at the same time or the body control module, BCM, having some issue that affected both, the ground wire is the only other thing I can think of. The ground for the low beams and high beams have a common mount point, but do not share a common ground wire which is the ground wire for both the DRL and the low beams. So, it could possibly be broken or loose as well.

Hello,

Here are the headlight wiring diagrams so you can see how the system works along with a guide that will show you how to check the wiring.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Cheers

Have a pro look at it as the harness may have burnt up to the multi function switch. Especially with the smoke. Unless you left something over the light sensor you can also check the headlight relay behind center of dash but it may be a body module so a pro will need to scan it to see if there are any code. You might try swith ing the headlamp relay with a like one and see if that cures it as the relay may have stuck. See diagram

If the alternator is over charging you will have a faulty voltage regulator, get this checked first.

Check the voltage at the main battery cable at the back of the alternator, let me know what that is at idle and at higher engine speed.

Inspect socket/wiring for corrosion-Could be grounding out or the ground is open on that side-check ground point G-101 at left front corner of vehicle

Ok first you need to open the hood and you should see a couple of black metal tabs that look like you could pull on them. Pull those (2 per headlight assemble) and then pull the assemble out in your hands and change the bulb then put it back and push the clips back down.

If you open the hood, you can gain access to the socket from behind the headlamp assembly.

There is nothing you can do about this unless it's a ton of water then you can drain it out but it will accumulate again. Other than new headlights is about the only thing you can do. A seal is probably broken in them.
