My driver side low beam recently stopped working. I tried replacing the bulb, which didn't work. If I switch my headlights (i.e. put plug my driver side in my passenger) it works, so I know its not in the housing. I'm not sure which wires in the harness go to the low beams, so I'm not sure how to check them.

Anyone able to help me with this? I'm not sure where to go from here without taking it to a mechanic.

 

Did you check the connector for the bulb?

 

Check the fuse labeled DRL/EXIT LTS located in the upper fuse panel under hood on the passenger side.

 

I assume the connector is good. I plugged the driver headlight into the passenger side, and it works fine.

I checked the fuse and it is fine.

 

That would verify the bulb is okay, but not the connector that plugs into the bulb on the driver side. Check for voltage at the connector with a multimeter. If you don't get a reading backprobe it to see if power is making it to the connector. If you have power into but not out of the connector you found the problem. Replace the connector.

 

Sorry, I wasn't being clear. I took the whole headlight assembly from the driver side and plugged it into the passenger side. Not just the light.

Do you know which wires in the harness would be for the low beam? IIRC, there are 8 or so on it.

 

Off hand I don't recall which wires in the connector are for the low beam, but you should be able to determine which they are by using a multimeter and checking for continuity between the connector at the bulb and the connector where the main harness plugs into the light assembly. Once you determine which they are match them to the harness connector.

 

I took it to a shop to get it looked at. There is power to the light, but no ground. He said something like the driver's side headlight is tied into the passenger side, and the wire (pink?) between these points is likely bad. Hoping I remembered this correctly.
