2007 mustang AC/Heater controls messed up after sound system install

I recently changed out my head unit on my 2007 v6 mustang. I read about a lot of people having AC issues after changing their head units, but my issue is slightly different. The blowers work fine and so does the cold and hot air, but the AC only blows cold when set to full cold, if I move the knob even one tick away from full cold, the air turns fire hot. The rear window defrost button also does not turn off. I checked the wires and connecters for the AC controls and everything looks fine. Is there anything else besides a bad climate control that can cause this problem?
