Blower motor not working
2002 northface with auto climate control blower motor does not work, all fuses
are good, do i need to replace the blower motor relay
If there is more than one relay the same in truck you can simply swap them to trouble shoot that part. But...There's also a resistor in the duct work that can fail. Did you loose the blower motor one speed at a time until you only had high speed and then lost that too? That's a sure sign its the resistor. A bit of googling will tell you its location and how to get it out.
