Amperage and voltage are inversley proportionate if you reduce the voltage to a blower motor you are increasing the amperage the blower motor is using. This will cause the blower to die sooner not last longer. As an example:
If your blower motor is rated at 24v and used 10amps to run, it would require 20amps to run at 12v and the windings in the blower may tolerate it for a while, but not for long.
