Heat Issues
#2
I'm assuming that your engine is heating up properly and your coolant level is correct. You may have a temp door problem. There are electric motors that move the temp door and the mode door that may not be working. When you change you settings from hot to cold and defrost to floor dose it seem to be changing anything.
