[W126 Coupe] white hose on left side of center console

[Shayegan, Richard]

While running the new wires for the new speakers, I came across a white
hose (well, shaped like a hose, but it was made out of foam and had a
coiled wire in it) on the bottom left side of the center console. What's
this hose for? Mine had a tear in it, it doesn't look easy to replace (I
couldn't see either end of it) so I just patched it with duct tape. It
seems to be involved with the climate control (when I would turn on the
climate control I would feel light airflow coming out of it).
Thanks,
Richard
