[xj] Warm air from vents

I’m getting hot air from my Windscreen vents in the upper dash. None of the
climate controls are turn on. The blower is not running. I think my Jag might
have the “Gardiner Mod” unless something else is causing it. It may have been
installed by a PO. But I don’t need warm air here in Mississippi now. How can
I turn this off or at least change the warm air to ambient air. I read the
archives about the Gardiner modification, but couldn’t gather much about how
to change the temp of the air coming in from hot to normal.

On a related note, I think my heater valve is stuck in the closed position.
The plunger is not extended downward. Could this be related to hot air from
the Windscreen defrost vents?
