Doing a little maintenance on Cheapster Cherokee and saw this guy unattached to anything:

just hanging down between the washer fluid and coolant bottles. The line goes into the dash


So should it be plugged in somewhere? The only place I saw that could be proper is this vacuum canister with a large opening plugged up either with a plug or RTV sealant.

Also noticed that someone put the wrong AC hoses on this vehicle at some point in its life. Note the worn down spot on the underside of the hood:


The ac compressor clutch isn’t engaging so no air. Also it only blows through the defrost vents at the top. Since the mix doors are vacuum-powered and that line goes into the dash, I think it might be the issue.
