Want this question answered?
We just put a new cd player in my daughters car. we had it done professionally but now we have no heat coming out of our heater, just cold air. Do you think they did something wrong? Could it be the blend door
Sounds like your blend door may be broken. the blend door opens and closes on the heater core to allow heat into the cab by letting the air blow over the heater core. The heater core basically looks like a small radiator and when the blend door gets opened up, it allows to air from the blower motor to blow through the heater core fins and that heats the air before it is pushed out the vents into the cab... Check out www.heatertreater.net Those guys have videos on there of what I am talking about. It may not be your blend door though. Could also be the blend door motor or the dial to turn from cold to hot... I would check that blend door first though...
The heater blend door is not run by vacuum. It is run by an electric actuator.
It does not. It is cable controlled thru a "blend door". If you are having no heat, it could be because of a clogged heater core, or the cable has came off the blend door, or the blend door control.
How do I locate the heater blend door actuator in a Ford f150 pickup
I do not have heat in the car and the blend door clicks. How do I access the blend door in a 2005 Ford Explorer?
First check the fuses then check your blower fan then check the blend door and blend door actuator and then the control panel
Low on coolant, stuck open thermostat, plugged heater core, faulty temperature blend door,
The heater core is like a small radiator - the engine coolant flows through the heater core . The blend door mixes varying amounts of unheated air with the heated air to regulate the temperature
Yes, it is possible the blend door is broken in the heat position.

You either have a bad a/c heater controller or a bad or weak a/c heater blend door..........
