My AC is currently only blowing through the defrost vents. Figured out the problem was from a broken tube running from the vacuum reservoir to the HVAC check valve. Pictured below is the actual tube.

I have a couple questions;

What kind of tube is it/where can I find it?
How do i go about replacing it, the tube runs into the firewall but I can’t see where it comes out the other side?

Thanks in advanced!

Maybe you can connect them back together with these.

You should be able to go to an auto parts store and get vacuum line if you want to install new lines.
