Easy blend door question

[footee]

I'm workin on an 04 Explorer. Noticed the vents weren't blowing as hard as they should. I got behind the glovebox and noticed the tab is broken on the door, actuator working properly. Can just that tab be replaced or do I need to get an entire blend door? ...and go through the headache of changing that...

So you think the Blend Door which is for warm or cold, is blocking the air flow from the fan?

Good look here at the setup inside: http://www.dormanproducts.com/digitalassets/document/902-224_IS.PDF

Not sure if you can just get the tabs, but you may be able to make something that will work.

The blend door that shits the airflow off to the vents. It's the same concept, the tab that the actuator connects to, to open and close it. I have no idea how it got broken off but it has.

Thats not technically the "blend door" then, blend door is strictly warm or cold air selection and is electric, other doors are vacuum operated.
In diagram it is labeled "temp door", and controlled by "Blend door actuator" which is why is it called Blend Door by most, lol.
It either block off heater core from air flow or opens heater core to air flow, I guess if it broke and got lodged at an angle it could block air flow.

Is this the door you mean or is it another door in that diagram?

I understand what you're saying. I would have to call it the air to panel door then. It is vacuum operated. I can see it's clearly broken from the vacuum actuator. If that piece just pops off and another can be installed, that would make life a whole lot easier.

I have never had to replace anything on the vacuum side in the air ducts so I am ignorant.

So it would be the arm of that door that is broken?

Glue gun, "plastic weld" maybe?

Sorry can't find a picture of it

And the other thing is why did it break?
Does the door move easily?

My thoughts exactly. I bought it that way. The door seem to move fine as does the actuator. I agree it's a pretty odd for it to break at that point.
