There is one more thing, The blend door may be stuck! Stick your head under the dash and operate the temp knob, see if the servo for the door works.

Yes if the door your speaking of which controls the air from the vents to the floor. Every now and then by tapping on the bottom of the panel outside of the heater core I can hear something open up and then there heat but it doesnt last to long

You need to figure out which door it is, the one I want you to find just moves when the temp dial is turned, not floor or defrost knob. When you find that door, remove the controler, be it electrical, or vacuum operated, and see if you can spray some white litium grease on the shaft, work it by hand until it frees up! Then put it back together. Open the hood, look at the two heater hoses going into the car, does one of them have a valve on it? Watch that valve as heat is turned on and off, that may also be a problem.
