Thank you Horack. It is always good to hear personal experiences about any fix of any system. Your input helps future lookers and other FF members.
Thank you for sharing your results and the fix. Great work Charles!I had a similar issue with my 05 Focus:
Blower worked on 2-3-4 (I suspect it was just spinning extremely slowly on 1)
AC only worked on 1
Replaced the resistor yesterday and it solved both problems.[ffrocks]
Yes, the resistor pack does control the voltage to the blower fan motor. The 3 resistors drop voltage to provide speeds 1, 2, & 3.I don’t understand why the resistor pack was the issue, doesn’t that just control the voltage to the fan?
