A 2001 Chrysler Town and Country does not have a water control valve in the heater system. The cabin temperature is controlled with electric motors on airflow control doors.
Sometimes, the best way to fix a heater control valve on a 1996 Town Car is to put in a new heater control panel. A used heater control panel can be found in an automobile salvage yard for less than the cost of a new one.
No such part on a Town and Country. There is a blend air motor under the dash that controls the heater output.

Blower Motor Resistor is located under the hood on the fire wall behind the right valve cover and the heater hose. It's about the size of a deck of playing cards.
