Can someone please give me some kind of idea what is wrong with my heater?? It only blows out cold air. You have to put the switch on a certain setting between hot and cold or it will make an annoying clicking noise.
 
Sounds like you have a blend door that is stuck closed.
The blend door is what allows cold or hot air into the blower air that blows onto the interior of the vehicle if it sticks open you get hot air all the time if it sticks closed you get cold air all the time.
the sound is comming from the vacuum pull off trying to open the door.
Since all of this is under the dash I recommend oyu take it to a certified tech.
Happy heating
