I was helping a friend out today because their fan doesn't seem to be blowing as strong as it should. I took out the resistor and took some readings.

these were the values, I didn't write them down but I remember the ranges
low - 200k range <--that number was huge it surprised me
medium-low 20K range
medium-high 2K range
High -100 ohms...ish

My thought is "High" should be 0 ohms or very close to it, the first two numbers were huge.

My question is what are the resistance specs for this unit? I looked at the forums and couldn't find it. I even called a ford dealership to ask and they didn't even understand me...
I don't want to just buy another if this resistor is still in spec, and later realize its the motor itself.

Can someone help?
 






Hook the motor up to 12v directly and get the "blow result".... that will like tell you if its the motor.
 






Here's the diagram with the resistor values.
