  • I am trying to hook up lights on my 2007 Rainier running boards. Using the overhead courtesy lamps circuit to control. Board lights to come on and go off when the courtesy lights come on and go off. Problem board lights 12 v the courtesy lamps 8v.
    new lights are LEDs. Which circuit and where might it be located to tap into to provide 12v to lights and work with courtesy light circuit.
  • I have the same problem on my 2004 Rainier. Went to Buick Rainier Electrical Problems and there were no comments when I searched.

    This issues is killing me. While driving at night the lights go off and I can't turn it back on. It's extremely dangerous. I can do two things; continue to drive for about 5-10 min and it will go back on. Or pull over turn off the engine and wait about 10-15 min and start the car again. But when I drive it will go off again. This issue is intermittent it happens whenever it feels like it.

    I did a few things. Unhooked my battery to reset all electrical systems. It worked for a few days and then started again. None of the fuses are blown. I turn on and off lights when i exit or lock/unlock the doors but that didnt work. I took it in and no one knows whats wrong.

    Has this ever happened to anyone? Does anyone know what is wrong?

    I'm incredibly frustrated about this. I hope someone can help.
