I've been having no luck with getting my passenger side headlight to work. Ive tried two bulbs and only the high beams will work on that side when I replace it. Any ideas? It doesn't appear to be the wiring harness in the headlight assembly itself because when I checked the power, it shows all connections are making power. Could it be the Lighting Control Module? I've never experienced this before and its weird for the high beam only working.
73 is the best number.
Are you sure you have power at the bulb connection? There are separate fuses for the low beams. #26 in the cabin fuse box is for the passenger side.

Would the left and right be separate? Because I get both high beams and only the drivers side low beam work.

As I stated, there are separate fuses for the low beams. The fuse for the passenger side low beam is #26 in the cabin fuse box.

Ok thanks I'll check it out

Also check the pins for the quick connection. I've seen them pushed down so no connection.
You can remove the light assy and plug it into the other side of the car / use the other headlights quick connection to isolate if it's in the headlights wiring or the cars wiring

The lighting control module powers both low beams from one single output but as stated before they are both fused. So it's not your LCMs fault.

GAME OVER, YOU LOSE!
Did the light suddenly stop working or did it stop working after you did something to the car? Could make a difference in the diagnosis.

^^^ What Bob said, I discovered this by accident, L/S LED bulb burned up, causing the fuse to blow. Put original back in, still no light, changed fuse, lit!
MARAUDERS get me ****!
