Temperature control problem on 2006 Ford Fusion

My temperature control on the dash is all the way to the coldest setting but it is still blowing hot air from the heater. Will not switch back over to AC. Sometimes, very rarely, it will be stuck on AC and will not switch back to heat. Also, the adjustment settings for air flow location does not work, will only blow from dash vents and not defroster.

how hard is it to change the blend door? Is it accessible or does the dash have to be removed?
