Location of the resister for the heater on 2002 Kia Spectra

The heater only works in the "high position. I replaced the contol panel, but from what I have read...it sounds like the resister is gone. Where is it located and is it an easy fix for some what experienced mechanic

It is located in the passenger foot well compartment at the bottom of the heater housing four wires going to it in a square pattern to screws holding it in place to the heater housing. Green/Orange, Green, Green/White, Green/Red.
$45 for part, .5 hour to replace.
