Fuse #12 (8a) regulates the rear dome light, central door lock vacuum system, and the anti-theft security system on my 1990 190E. The fuse has blown twice in the past 24 hours. I have also noticed the the lower copper contact is not attatched to the fuse board; it seems to have overheated and broken off. My question is three-fold. 1) Do I need to replace the fuse box due to #12 slot being broken? 2) Should the anti-theft system be on such a low amperage? 3) How can I disconnect the anti-theft system?

#12 is listed as regulating the central vacuum, dome light, and seat adjusters. The seat adjusters are on another fuse because they are not affected by the blown fuse. Any help would be greatly appreciated.
