Number 19 fuse melted

[vinaslinis]

Hello, I am newbie here, I have 1988 bmw 750il, I found my fuse number 19 is melted I know it is blower motor fuse, so I found in this forum some info but sorry I don't get it, so what can cause this problem? blower motor needs to be replaced or rebuilt? or I have problems with sword? ( my ac switch worked on all positions without any issues) or there is another resistor somewhere around blower motor? Thank you

Fuse 19 is for automatic climate control, also fuse 8,9,20, 21 and 29 http://shark.armchair.mb.ca/~dave/BMW/e32/e32_88.pdf
Is the blower speed adjustable in all ranges?
Does the blower motor make noise?

climate control worked on all speeds just fine I have cold ac, on my cover says " nr 19 blower motor" , now when I busted out that slot blower ofc doesn't work, I gonna replace fuse slots on weekend from part car, also gonna do inspection of blower motor. so I am just curious what can cause that fuse to melt

Heater/blower motor removal and testing might help http://www.nmia.com/~dgnrg/page_2.htm
In case you have a parts car, also try swopping the heater sword.
