My Buick Roadmaster Esteate Wagon's Interior lights will not go off. I replaced the headlight dimmer switch and the twighlight (autolamp) switch and they still won't go off. If I take the fuse out, I get a buzzing sound from the fuse box. The lights will go out if I turn the ignition on and off and do not open the doors???
