And I'll be even more direct than I was in my previous posts here ... Don't believe what you read or see on the intertubes on this. It IS more complex than most think.

If you've got a True RMS voltmeter, you can measure voltage on the control wire.

In my case, doing all the above and a few more allowed me to become fully convinced that the power and signal going to the fan all made sense, and were there. So with the fan not spinning, it only remains to swap in a new fan.

For a still unknown reason, my PA Soft BMW Scanner 1.4 did not run this time. I was going to try installing it from scratch on a different laptop, but at this point, I don't think it would tell me anything new.

And in defense of @upallnight, in exchange for the occasional rough comment like that, he has probably the highest batting average on here for tough problems. I'll take that over friendly wrong answers any day.

Good luck getting this solved.
