Hello,

Thank You for your answer, but I did check the ground and the other wires and connection points. That car has never done this before, and I bought it brand new in Dec. 2004. So I checked the BCM fuses and found one blown replaced it and know it all works! Thanks :)

At one time I had the drivers side low beam headlight go out. I replaced the buld and it worked for about two hours. Then the pass side went out replaced the bulb and it worked. At the time to check headlights the drivers side went out. I can not keep replacing the bulbs. Is there a way to get a wiring diagram to trace wires to try to find the problem. Thank you in advance. Jim

Found the trouble to the drivers headlight low not working. There must have been a repair to replace the socket for the headlight, because one of the splices came apart.Repair the splice and now the headlight works.
