The only way it will give me Hot air is when I select the Highest temp indicated by Hi on screen.
I also have a popping sound which I think is comming from cooling system although Im not certain of this..And may not be related to the temp select issue
Any ideas?

Assuming you've already dealt with the foam deterioration of the blend flap, it's likely the blend flap actuator.
