HI i have a 1995 850 2.3L turbo and i was checking the fuses the other day because my map lights were not working and while i was checking the fuses i noticed number 5 was melted in where the fuse sits, which is for the blower motor , so with the car running if you pull the fuse it sparks a lot but doesn't pop and if i leave it in it gets really hot , all of this is happening with the a/c and fan running when i shut the a/c and fan off and pull the fuse it dose not spark .
So i replaced the blower motor today thinking it was the problem but no nothing still the same .
hopefully someone on here can point me into the right direction
