Hello everyone, it's my first post here, I've got a strange electrical issue with my 2005 E90 325i(type VB11). Electric mirror adjustment doesn't really work. It only works when footwell lights are on and then those adjust only in some directions(driver's one adjust in all directions apart going down while passenger's only adjust to the right). Mirrors heat up correctly and don't adjust at all if footwell lights are off. I've checked the fuses, F27(for preLCI cars) was blown(5A), replacing it with new 5A fuse caused it blow immediately, I have no other 5A fuse so right now I've placed 15A one and so far it hasn't blown although mirrors work the same way as they did with a blown fuse. Weird thing is that mirrors work that way with or without F27 fuse(which makes me think it wasn't the mirrors fuse but for some reason it keeps blowing so there must be some kind of issue for sure). F21 fuse was fine although just to be on the safe side I replaced it as well. Do you have any suggestions what should I check? Mirrors don't work since I've got the car. INPA shows no codes corresponding to the mirrors(there's one code for AHL motor in right headlight).

that mean that you have short circuit in powering mirrors and you mirror get power when footwell light on for some reason
so you need to disconnect mirrors and test circuit for short to ground those which are not ground by function
