Blower fan does not work properly

Hi and thanks for using 2CarPros.com.

If the motor was turning slower than it should be, it may be bad. Have you checked to see if there is power to the blower motor since you replaced the resister? Also, have you confirmed the motor has a good ground and nothing is blocking the fan?
