The blower motor resistor needs to be replaced. It down by the blower motor, a little tight spot but easy to change. I would recommend buying a OEM resistor because they are just better, I have a 2010 Impala, it took 5 aftermarket resistors finally until I got one to last more than a week.

You may need to add to your radiator coolant, it's probably to low to push the fluid through the heater hoses.
