Hi there, I see Bobby is still online. Do you still need help?

Expert:  BOBBYSS replied 1 year ago.

Thanks for the information. I am sorry that I could not get back to you yesterday. Can you tell me if all of the other exterior lights work? Do you have a voltage meter to run some tests?

Customer: replied 1 year ago.
All the other light are functioning correctly. I've checked the 50 Amp fuse in the fuse box under the hood and it is not blown. Is there a relay for the headlights that is in line with the headlight switch and the headlights and if so, where might it be?
Customer: replied 1 year ago.
I do have a voltage meter. is there some sort of diagram of the connector to the headlight showing what the pin assignments?
Expert:  Reggie Whiddon replied 1 year ago.

Hello i am Reggie okay your headlights i am looking at the diagram now your headlights leave the switch and go to your daytime running lamps module it is most likely at fault

Expert:  Reggie Whiddon replied 1 year ago.

under left side of instrument panel taped to the harness you will see the yellow wire from hedlights it should have about 5 or 6 wires in the connector when you locate it look for the yellow wire to have voltage when you have lights turned on
