[T3] Blower Motor

[William J]

 Jim :

 From what I can tell if the Bentley schematic is correct the fan looks like 
it has 2 coils for the fan motor yet the schem may not reflect reality. 
Since there are 2 wires that lead right into the fan housing 3 counting the 
ground where is this resistor .

 I'm trying to imagine how a resistor failing would cause the low speed 
switch contact to burn unless the wire to the resistor is now touching 
something internal . It did work on low for a while then the second switch I 
had did the same thing.

 Yes my date was off having some issues with this old XP pro computer, Think 
I've got that fixed now.
