Heat working, but only blows on windshield vents??

My heater is working and blows hot air just fine, no smells or lukewarm air.

Problem is, no matter what position the selector switch is in, it only blows out the defroster vents.... Anyone had this problem before? And if so, how do I fix it?

GTyankee,

Thanks for the links. Have watched a couple and will watch the others. Looks like it could be the blend door or vac line problem so I will get to looking this weekend and see if I can't nail down the problem. Thank God I still have heat at least!
