[BMRBOI 8]

Hi I have a 92 325i, my windows don’t work (unless you open the door) same goes for my interior lights. Ive been told it’s the BCM, where do I locate this item? Any one has pictures of it? I have a few spare modules around home but im not sure of there uses or where they can be located hah! Anyone who could share their knowledge would be much appreciated.
