While we can't know what temperature the engine is really running,
it's certainly somewhere that Chrysler called normal. have you
checked for blockage in the heater core? Proper function of the
blend-air door? If this vehicle can shut off water to the heater core
when the heater is off, is that valve functioning?

Jumping from "my heater isn't hot enough" to "I need my engine to run
hotter in spite of the temp gauge" is quite a leap.

The difference between thermostats will make no significant difference
in the temperature of the air blowing on the windshield. Yer problem is
in the air handling for the defroster or the heat exchanger (heater core).

Make sure the defroster fan is working. Make sure there are no air leaks
(feel around under the dash, there may be vents not closing), make sure
the heater core is very hot.

Did you try turning the fan on high? What is the temp knob set at? Full red
(hot)?

I find that the heater output on my 2002 Caravan is marginal during
bitterly cold days when the temp drops below 10 degrees F or so.

On the standard Voyager/Caravan without the rear heater, the heater
output in terms terms of BTU's is simply marginal in my opinion.
The air does come out of the heater at a sufficiently hot temp.
There is simply not enough capacity. When I put the fan on its highest
speed, the air temp actually drops. This tells me that the heater core
simply isn't adequate.

I've also had the problem of ice forming on the windshield under such
conditions.

You are trying to heat a big box with a marginal heater.
I doubt that there is much that can be done.
My dealer has said that others have a similar complaint.

In reality, if the standard heater was perfectly adequate, why would
Chrysler/Dodge offer an optional rear heater???
