Heater just stopped working all at once, we have already changed the thermostat & antifreexe, I do not hear a clicking noise as some others have stated, it blows just does not get warm

Do you
have the same problem?

Check this for me. With the engine hot and the heater on, feel both heater core hoses. Both should be hot. If one is hot and the other isn't, chances are the heater core is plugged. If both are hot, chances are the blend air door is stuck only allowing cold air to enter the vehicle.

Let me know what you find. NOTE: Since it started all at once, if sounds like the door.

It is part of the HVAC system and is located near the heater core in the heater core box.

Glad to help. Let us know if you have questions in the future.

By the way, was it the blend door actuator?

It sure was, we took out the glove box lining and took out the actuator box(great video of how-to on you tube)and the pin would not turn so we knew from the video that this was the culprit, the piece was only around $42, so it was much better than it being the blender door itself, once again thanks for all the help
