On my 98 Yukon, if the dome over ride button is in the out position, the interior lights come on and stay on, regardless if a door is open or not, instead of the interior lights only coming on when a door is open.
My first guesses are that either the over-ride button switch on the dash could be bad, or, one of the door closed sensing buttons could be bad, making it appear that a door is always open.
Has anyone had a similar problem, and if so, how did you troubleshoot it, and what did you determine was the problem?
This vehicle is a recent acquisition, and I don't have much history on it, so I don't know when or how this problem started.
Thanks
