Maintenance/Repairs

My 07 Impala stopped blowing air so I got a new blower motor. I take the old one out, connect the plug to the new one and nothing. I took a multi meter and connected it’s leads to the plug that goes to the blower motor to see if it’s getting power. As I turned the fan up and down, the meter also went up and down. I’m assuming it’s getting power. Since the meter went up and down along with the fan speed dial, I’m assuming the resistor is working. Next I connect the new blower motor plug with some wires directly to the car battery to make sure the it’s not defective. The blower motor seemed to work fine. What is my next step in troubleshooting this? Thanks in advance.
