No Heat but not overheating
 
On Sunday I replaced my battery. Everything was working just fine. Monday morning I went out to start my car and there was no heat. There is cold air blowing out of the front vents but there is nothing blowing out of the defrost vents up front. The Rear Defrost works just fine. I made sure there was plenty of coolant also. Please help!!!

Also it is not overheating and the temperature gauge is reading in the middle like it always has. I dont think its the thermostat but I really have no clue.

May need to to recal the ATC
RECALIBRATING YOUR AC:

1. Start the engine but do not move the vehicle.
2. Set the Temp control to 75 degrees.
3. Press and hold the Floor, Mix (vent/defrost) and Defrost buttons at the same time. The floor is a bottom button and the others are upper.

4. The control head will begin to blink and enter a diagnostic mode.
5. Release the Floor, Mix and Defrost buttons.
