I had exactly the same thing with my '93 Ghibli when I was working on the radio. One of the fuses had blown and because of the poor design of the fusebox, you get current flowing in parts of the fusebox where it shoud not.
Also in my case I heard the little speaker in the passenger footwel buzz when one of the doors was open. After closing the doors the noise was gone, but when locking one of the doors by hand while in the car, some funny noise came up as well. Unlocking the door solved the problem.
If I am not mistaken it was the fuse for the interior lights (these should not work at this moment if my theory is correct).
