I am trying to make sense of this heater.What is his function ? Why do
we have to turn a switch manually in order to avoid hot air from coming
out ? Is it something that recirculates inside air only ?
 Is this heater meant to run in the summer only for fresh air ? or is it
also meant for heating rear passenger compartment ? And what are those
vent above the slidind door ? Is it for Air cond ? I can't get any warm
air coming from these vent ... As you see, I am new to this business.

By the way, would somebody have the paint code for the pop-up roof on a
1991 Westy Silver. The pop-up roof is kind of grey and I am looking for
some touch-up paint... The dealer in Vancouver ( Clarkdale) doesn't
know...sic...
