Pint,
There is a VERY good reason for the second unit in larger cars and vans.
It is call 100+ degree days and A LOT of glass! and no the second unit
usually does not have separate controls for temp but for on/off, but the
second heaters (which I installed one in my 69) had two switches - fan speed
and air direction (under seat or defrost). The second heater was great when
I first started the car on a HOT PHOENIX day, to blast the hot air out of
the rear window to cycle through the front cooling unit. And talk about
melting snow off the back window - less than 2 minutes with 3 inches of snow
in a blizzard in Flagstaff. The pipes came in two pieces, unlike the ones
for the regular chrysler which were one unit. The heat was contolled with
four vacuum hoses.
The Rear air is ONLY mentioned in a couple of places in the FSM. I was
able to determine the rest from the parts manuals and the dimbles in the
floor behind the back seat.
