Smile 2003 HVAC Issue

My '03 quad cab has an HVAC issue that I am troubleshooting and I'd sure like some help.

First, I have verified that all the doors operate as they should and have replaced the recirc door. I still seem to have this problem: The passenger vents blow hot when the heat and vents are on but the driver side blows luke warm at best. Also, when the temp knob is set all the way to cold the passenger vents still blow some heat. I don't know what a "DUAL ZONE" system is supposed to look like but I don't think I've got it. And I'm not trilled at the prospect of removing the dash again but...

Any ideas?
