battery flat

Hi, this morning battery flat.
I had this months ago before and had a lost of 1A/h at the battery. Removed fuse 16 and problem was solved. Without these fuse a lost of 0.3 A. I think that is normal, there are still things using power. Well, after removing fuse 16 everything was working except the auto dimming mirror. So I decided last week to reconnect the fuse and the mirror works again. BUT . . . . again a flat battery after 24 hours.
How can it be that fuse 16 takes so much Ampere? Is it the mirror or are there other parts that takes power from this fuse.
I have no wire diagram so cannot search what these parts are.
Can somebody help me?
Gerard

For the original design of fusebox, which you will most likely have on a 2000 model year car, RAVE says it feeds the "accessory socket relay".

To answer your question, fuse 16 is passing a lot of current because there's an abnormally low resistance somewhere in the circuit.

With the car's electronics in proper "sleep" mode, i.e. with everything shut down and after about 20 minutes, 0.3A is far too high. The current consumption should ideally be less than 50mA.
