I've measured my blower, and the power draw is proportional to the speed setting - low speed uses less than high speed. Sitting with the engine off, reading battery voltage, and each higher setting drops the voltage another 0.1. Back to a lower setting and that 0.1 comes back. I'm not sure about the why or how, though.
Volts - Fan setting
12.2 - Off
12.1 - 1
12.0 - 2
11.9 - 3
11.8 - 4

Reason: add actual numbers
