Check the blend air door. It is located near the heater core. If it is stuck, then you won't get heat

I saw your other posts before seeing this one, so I've responded several times.
The blend door actuator on the drivers side (closest tot he floor) is most likely the one which controls the heater door. Remove the actuator and turn the rod by hand. With the engine running and at normal temperature you should then feel heat. Try this several times to be sure its the proper one. If so then repalce the actuator.
