I was driving today and a coil-wrapped transparent conduit hose dropped into the passenger footwell. Its about 18" -20" long, about 1" round. Looks like it would hook up from environmental controls to an interior car vent. Anyone have any idea where its from? What it is? How I can reinstall it?

 

It connects to the AC for the glovebox. From memory, just slide it back on, but it will take some serious twisting to get to where you can see where it goes.
