Blower fan not working

What is your question?

I replaced the blower reaistor, the blower motor and the relay. Fan still not working. I was checking the relay fuse prior to replacing and saw it smoking. Curious if this is now a wire issue at the relay box? And if so. How would I go about fixing?

What makes this problem better or worse?

Nothing better or worse
