I read over the recalls and they do have recalls on brake and turn signal lights but not the low beam headlights while driving at night.

Sounds like the relay or headlamp driver module relay 46, for the headlights is going bad, though.
Or, it could alternatively be bad grounding of wire somewhere or bad wiring in general.

I would check in the underhood fuse box for the relay and see if wiggling it to ensure a good connection helps matters.

Headlights no longer come on


You probably have two separate problems. If both your low beam headlights were going on and off, the most likely reason is the low beam headlight relay located in the underhood fuse panel. It is designated as #46. Try switching it with #45 relay, right next to it, for troubleshooting purposes.
For the fog light check relay #39

The DRL Module controls the operation of the DRL's and the automatic headlights. A faulty DRL Module is the most common cause of low beam failure. The DRL Module is located under the dash, just above the brake pedal.

Low Beam headlights not working


The daytime running lights run the high beam bulbs at low voltage so it sounds like you need to put the relays back where they were and either replace the low beam bulbs or repair the wiring to them.Also the relay you removed could be defective.

Driving down highway last night and lowbeams turned off. High beams worked, couple of miles later, low beams came back on.


You may want to check the terminals at the back of the headlight. Normally this is caused by loose connections. Other than that check the rest of the wiring and the relay.

First face the vehicle so the battery in on the right.
Second open hood.
Third Remove the Grill by pushing firmly on two retainer clips that are on the top, use the wide slot screwdriver to get the rest of the clips off. Pull up gently on the grill it should then pop out. The grill extends under each headlight assemblymag-glass_10x10.gif any other retainer clips should release when the grill in popped out.
  • Step 2 Fourth on top of the headlight assembly you will see one 1" tab on the right and left side, pull the tabs upward about two inches and this should release the headlight assembly. You then should be able to pull the headlight assembly out toward you.
  • Step 3 Finally at the back of the headlight assembly you will see two rubber caps one for low beam and one for high beam, the white base is for the low beam and the black base is for the high beam. Unsnap the wire harness from the bulb base, turn the bulb clockwise.

    Replace the bulbs high beam on the outside and low beam on the inside.

    Try swapping #45 cooling fan relay and #46 HDM (headlight driver module) relay in the underhood fuse block. These are solid state modules and are not like conventional relays.
