Are you uncertain that the blower motor and resistor were replaced?

I have seen where a blower motor has bad bearings and this causes the resistor pack to burn out prematurely.

Even though the blower was replaced, you may have gotten a bad one.

You will have to test the blower by jumping from a known hot lead to check if it is even working.
