I had a guy come in yesterday with the same problem in a Regal GS. It ended up being his dimmer switch had gone out. The radio and climate controls would black out, along with the dash lights not coming on, when the headlights came on, and adjusting the dimmer did nothing. He replaced the switch, and all was well.

I pulled both lamps and they passed, as did the new spare bulb I installed as a control. I dont even get the high beam indicator light and it is brilliant blue when on.

thanks

Hey guys, long weekend was nice and long.

Quick update, I swapped out the master light switch, not it. I also checked the photo cell and P/Brake switch as well. I have used some elect contact cleaner everywhere I could and will attack it again this week. I have some more ideas. Back soon..

I am not done yet, but I have ruled out pretty much all of the obvious. I have zero time on this car so I really dont know any of the electrical ties in with other systems. So I am almost done screwing around, off to GM to have one of the kids there have a go. My feeling all along is that they know what it is that is wrong and just dont want to give away the surpirse ending...
I told my wife that if the harness is done I am going to remove everything and drive in next years Smash up derby.

Thank you all for the help.

all stop,,,,,,okay more research (my buddy Dan)tells me that it is most likely the Daytime Running Lights Module.

I would like to know where it is located!!!!My auto recyler has mentioned that the same car just came in, so if I can find this part is located I will be that much farther ahead.

any ideas on where it is, colour, number, has the name on it (doubtful)...

thanx again
