And you have already replace the blower motor speed controller?

Customer: replied 10 months ago.
I think this is the blower motor relay
Customer: replied 10 months ago.
Customer: replied 10 months ago.
Any way to test the relay before swapping in new one?
Expert:  Ron replied 10 months ago.

Okay that is the relay , the more common cause for the blower to fail providing the blower motor is okay is usually a failed blower motor speed controller and not the relay. Before you replace any more parts are you able to do some testing for the blower motor speed controller?

Customer: replied 10 months ago.
but like I said, it was replaced with new. I have both right here
Customer: replied 10 months ago.
As an aside, this control was replaced just a little over a year ago when I only had high speed control

Well let start with rechecking it to be sure it has not failed. See the steps in the link below.

If it passes the testing then the nest steps would be to check the blower and the circuit to t.

See those steps here as well as the wiring diagram for testing reference. Start your testing for the blower on P1.
