[bmw] Blower Fan Motor

["Gary Dietz" <DietzGW@xxxxxxxxxxxxx>]

Hello all.  The blower fan motor in my 1984 733i is exhibiting 2
problems.  First, the variable speed doesn't work properly.  You can get
low speed (by setting it to one of the fixed positions) but on the
variable speed you only get high speed.    Second, it has started
squealing loudly, and sometimes doesn't run at all (particularly in very
cold weather).
 
So, I'm guessing I need to replace the blower motor.  How difficult of
a job is this?  Any recommendations on where to purchase a new motor? 
And any instructions on how to do the replacement job?
 
Thanks - Gary
