Howdy. Just in triage mode with my 1-day old Firebird acquisition. First annoying feature is the door buzzer goes off when either door is open independent of key position or key out of ignition entirely.

It will go off if I manually push the door switch, but I suspect this may something more sinister like a short or failed component wherever this door switch is run through (steering column?).

If anybody has any first-hand experience and/or can make some suggestions for debugging, I would be most grateful. My Kung Fu for electrical issues is about 5/10 (10 being a grand master), so I'm willing to fire up a volt meter, but thought I'd check in here first.

Thanks for listening!
