Probably your rear heater...........it's a heater core (plumbed to the
cooling system) and there's a fan in there too. The fan switch is to the
left of your heating/cooling levers on the dash. The lever on the side
truns the heat on and off --- experiment when you've got the engine up to
temperature  --- I can't remember off the top of my head which way is
on/off.

        Subject:        What is under my bench?

What is the gizmo box under my 86 Camper GL's rear bench?  It appears to
be 'stock' and it made by VW/Audio.  There is a valve that seems to turn
on/off, and some electrical wires going into the box.

Is it air conditioning?  Is it a heater for winter or perhaps a heater
for camping?
 I'd appreciate help to find out what this does, and also how to use it!

Thanks,
Shawn
