One More Update
Sorry to clog up a thread, but I wanted to update why this is important. Now that I have got this corrected, I can now actually regulate the heat coming from the blowers (both Defrost & Heat modes). Before I was only getting blazing hot air coming out, and now I can regulate it better.
