I have a 73 SE and all of a sudden some of the buzzers started acting weird!  First, the door/key in buzzer came on and wouldn't go off as well as the dome light.  Second, the lights-on buzzer starts buzzing when I turn the lights on driving down the road and won't go off unless I turn off the lights.  I have taken the door jamb switches out and checked for damaged wiring but found none.  Where are the switches located for these buzzers?  Any help would be appreciated!!

Ok, both buzzers even related to the door jam switch are wired independently from the dome light. I mean, the dome light is controled by a yellow wire to the switch while both buzzers are tapped into a black wire circuit to the switch.

Each circuit reachs one of the two prongs at switch, both to be triggered with the door ground signal.



So, PROBABLY somehow the black wire is being accidentally grounded. Either by a slightly damaged door jam switch (one of the prongs failing to ground) or the wire itself somewhere. Still with dome light working propperly
