Thread: Mystery Wire/Hose?

Yup, sucks great! : \

then thats a vac leak. seal that thing off, or get a new hose to run to your htr core.

Alright, I will seal it up and and order a new one. So its called a heater core vacuum hose?

Im really not sure what its called. Someone asked me where it went the other day. They said they usually see the middle of the vacuum manifold capped, theyve never actually seen a hose come off it. So I traced it down and took those pics. But I do know that if that thing is sucking air, you're loosing powah. I'll have to do some research to see what its function is.

Sounds good, and I would really like to know the "function" of this hose. Thanks!
Edit: It's sealed off good to last for now. Going to buy some brake cleaner and start testing some for more leaks while im at it. Two leaks at once so far..

Ok, apparently that line controls the switching of your airflow. I.E. Floor, Vent, Defrost. Have you noticed bad air flow, low heat or the controls not switching properly? I know in mine, when I switch to say, front defrost....I hear a little pssshhhh sound.

Yea, barely any air flow on full blast. And when I switch to to front top vents, or to bottom feet, It just blows everywhere evenly. Doesnt switch anywhere I want it to.
