Diagnosing blower motor in 2003 X5 3.0

[Corellian Corvette]

Today I purchased probably the nicest condition E53 I have ever seen, from lady who was meticulous about it. The car drives (and smells showroom fresh). I paid peanuts for the car due to one potential risk - the blower motor doesn't work.

The story I heard was that it was working fine, it hadn't been driven for a while, she went out to start it on a very cold day and broke the door handle, then while warming up the car the blower "just stopped"

Now I have X5's that are way more beat up, way more abused with way more miles and the blower motor works fine, so the bet I took is that the problem is actually the resistor (or something else) vs. the blower itself.

Question is if there are good suggestions on how to test this. I have used the scan tool to run the blower motor - nothing happens. I have checked the big 50amp fuses in the glove compartment and they were all fine.

When I test the buttons on the heater panel I *can* hear the actuators move. Although I am aware the problem can be with the heater panel as well.

Any other tips on checking the motor itself? I'm planning to buy the resistor for it but wanted to see if there was any other diagnosis in the meantime.

Thanks!
