defrost blows hot vents blow cold

a new HVAC problem here...when set on auto at my standard 70 degree setting the defrost vents on the dash all blow warm air as expected on a 40 degree day but all the upper vents are blowing cold air. even if I turn the temp dials up to 80 and adjust the air temp in Idrive for the hotter setting, the air is ice cold from the vents and hot on the upper defrost vents. Any ideas? I've kept my HVAC settings the same for the last 2 years so I noticed this problem immediately.
Thanks!
