<e36> HVAC Blower Motor

[Mike Schaublin <mschaublin@xxxxxxxxx>]

     First things first - thanks to all the contributors on the list for 
     sharing your collective wisdom.   Between the current postings and 
     archives from Dale B's page, I learned enough to do the routine 
     maintenance on my '94 325i that the dealer would've charged an arm 
     and a leg for.  
     
     On to the problem.  I recently replaced the microfilter, and just 
     the other day I noticed that my blower doesn't change speed as I 
     move the switch from position 2 to position 3.  Speeds 1,2 and 4 
     work as they should.  
     
     I figured this was an easy problem, and I got a new blower 
     resistor, installed it, and ... I still had the same problem!! So 
     my question is, what else could it be?  
     
     Since the fan works on all other speeds, I figure it can't be the 
     motor (or could it?).  The only other thing I can think of is the 
     switch.  Does anyone know of the fan switch ever failing on these?  
     
     The last thing I'm thinking is that in the thrashing around trying 
     to remove / install the microfilter, I pulled a wire out somewhere. 
      Does this sound possible?  If so, where is the blower motor and 
     the associated wiring?  
     
     Any help would be greatly appreciated.  We're approaching another 
     cold Michigan winter, so I'd like to get this sorted out.  
     
     Thanks,
