Hey guys I’ve had a 5th gen 4Runner for a few years and now I’m a new 80 owner as of last weekend...been doing some odd end repairs and while I was working on my a/c I noticed this hose right behind in between the block and firewall. Does anyone know what this hose is supposed to go to... looks like it’s been cut off and just left, been driving it a week with no issues. Any help would be great.

Looks like the rear heater has been aborted?
