    if blower motor is bad would have no air volume, if compressor is bad would have either leaks, noise, or no cold air

    The blower motor supplies the air volume into the cabin. The compressor only activates the Freon within the system. Keep in mind there is a blower motor resistor that also provides power (at different levels) to the blower motor.
