I installed a brand new blower motor (non-OEM) and it spins in the wrong direction, therefore there is very poor airflow coming out of the vents. How do I change the direction of the blower motor? I can not return the blower motor, so I'm stuck with it. I was thinking of cutting the two wires leading to the blower motor, switching them and then resoldering them. Any help would be greatly appreciated, because right now I'm at a total loss!
