PONTIAC G6 TOOL PROBLEM

2005 Pontiac G6 • 124,000 miles

I can not turn off my headlights. For some unknown reason the headlight won't go off. The only way that I have found to turn them off is to disconnect the battery. I have tried turning them off without the auto light sensor on or off and still they won't go off. All doors and the trunk is closed and they still won't go off. Any suggestions?

Do you have a multi meter to do some testing?

No, however I can purchase one. I have used one in the past. What should I be checking? Also, I removed the Relay 38 for my low beams and the lights went off. Do I need to reinstall to before I start?

Alright so its the low beams staying on?Also have you looked to see if there is another relay in the fuse box you can swap the low beam one with to see if it corrects the low beam beam lights staying on?A multi meter will be needed to trouble shoot the problem. You may even need a scan tool depending on the trouble tree. Let me check on that also please let me know about the relay swap possibility?

Yes, I switched a known good relay with the low beam relay and it did not fix the problem.

I. Just looked up repair info on your head lights and like I guessed the first step is check for codes in the body control module then use the scan to perform a head light output test with the scan tool which there talking about a tech2 scan tool the dealers use. The body control module controls the head lights on that car every diyer scan tool I can think of wont read body control. Module codes. So you would have to take it somewhere to get the codes read and write down the exact code numbers you have.

When the head lights are supposed to be off you can see if the white wire out of the head light switch is showing as a ground?Thats the input into the body control module to tell it to turn the head lights on.
