Default Root cause insight into the common BMW blower motor resistorfailures

If it's just a typical DC motor with two leads, apply 12V and
it should run full speed. You could [then] measure how many amps
it draws when running.

That makes a lot of sense!

Plus, it's easier to hook up leads to the harness connector than it
is to get a DMM lead on the impossibly hard-to-get-to 40Amp Fuse F76 for
the blower motor.
