What is this thing?

Hello everyone,

I was working on my truck today and noticed that this part had dry rotted and broke, problem is that I don't know what it is.

Truck details - 1996 F150 XL

Part in question

The yellow circle is what I'm trying to figure out, the blue line represents the hose that broke and where it went. I'm pretty sure that it's a hose and not a wire, there's nothing in it at all.

Thanks in advance.

It's a recirc door actuator. Where I live about 75% of trucks are driving around without it connected and the drivers have no idea. Generic 1/8" vacuum hose, or fuel hose for 2-stroke engines, will fix it.

Thanks y'all, I really appreciate it.

Any idea how much of a pain the replacement is? The blend door itself seems pretty easy, but the hose looks like it could be rough.

How hard is replacing the hose? Peel back the cover on the harness to find a good section of the hose. Run a piece of rubber vacuum hose from there to the actuator.

What does heat have to do with anything? It is the fresh air door. Not the temperature blend door.
