Your heat is not blowing out of your floor vents but they blow out of the defrost and upper vents what could be wrong?
My guess is that you have a vacuum line that isn't connected or that has a hole. In the cars I've driven, the blower blows air into the heater box, where the heater core lives. Vacuum lines open and close flaps (or doors) on the heater box to direct the air where the control unit says it should go. These lines are usually rubber tubing, and the ends can dry out and crack, causing leaks. I have never worked on a dodge, but I've replaced miles of vacuum line on other cars.
Why wont your heater change from feet to defrost but blows out hot air still?

Why does your Buick century's engine surge fast and slow when the heater is turned on in idle?
Depending on the year of the Buick Century it may have vacuum controlled heater blend doors. These use engine vacuum to move the doors that control where the heat is directed. If one of the vacuum lines has a hole in it, it would cause the engine to run unevenly due to the vacuum leak. Check the vacuum lines and listen for air leaks. You can also try spraying the vacuum lines with *small amounts* of carb cleaner, if the engine idle goes up when you spray a particular spot there is a vacuum leak there.
