The blower motor blows fine, the cabin air filter has been changed, but the air still isn’t blowing hard. A guy told me to reverse wiring to test polarity but I don’t know which wires to splice.

Good morning,

I posted the procedure below and attached a picture of the location of the blower for you to view.

I would suggest replacing the blower resistor as well. It is right next to the blower motor in the picture.
