Hi,
This may be similar to what I just fixed on an '00 dodge:
http://www.dodgeintrepid.net/showthread.php?t=89711

Accessing the Integrated Diagnostic System:

Procedure for Automatic Temp Control (ATC) equipped vehicles:

With the engine ON and the vehicle stopped set the temp to 75*F. Next hold down the Floor, Mix and Defrost buttons until the ATC display begins to flash. While the display is flashing, the system will run it's tests and calibrations.

When the display stops flashing, the tests and calibrations are complete.

The ATC display can only display one error code at a time. Any stored codes can be scrolled through by pressing the Panel mode button once for each code. DO NOT press any other button or you will have to start the test over. Note the codes and refer to the list below to determine what system is malfunctioning.

List of Climate Control DTCs:
23: Blend door actuator feedback failure (bad servo)
24: Mode door actuator feedback failure (bad servo)
25: Ambient temp sensor failure
26: ATC In Car thermister failure (ATC only, bad ATC head or ATC head disconnected while battery is connected)
27: ATC in car sensor failure (ATC only)
31: Recirculation door actuator stalled (stuck door or bad servo)
32: Blend door actuator stall failure (stuck door or bad servo)

34: Engine temperature message not received (ATC only, bad ATC head or bus failure)
35: Evaporator sensor failure
36: ATC control communication failure (bad ATC head or bus failure)
37: Blend door actuator output shorted to battery (bad servo or wiring fault)
38: Blend door actuator output shorted to ground (bad servo or wiring fault)
39: Mode door actuator output shorted to battery (bad servo or wiring fault)
40: Mode door actuator output shorted to ground (bad servo or wiring fault)
41: Recirculation door actuator output shorted to battery (bad servo or wiring fault)
42: Recirculation door actuator output shorted to ground (bad servo or wiring fault)
43: Common door shorted to battery (probable wiring fault, could be a servo that failed in an odd manner)

47: A/C switch failure (MTC only)
48: A/C control mode door input shorted to ground (MTC only, wiring fault or bad servo)
49: A/C control mode door input shorted to battery (MTC only, wiring fault or bad servo)

    When I did this on the '00 it caused the system to start working again. I didn't replace any parts.

2001 town and country 3.8 will not heat


Start the engine and drive it for 10 to 20 minutes. Stop, leave the engine running, open the hood. Feel the upper hose and the lower hose. Are they both cool? What does the temp gauge show? If both hoses are cool and the temp gauge is low than the t-stat is most likely stuck open.

I have a 2001 Chrysler town and country with a heater problem. all blowers work find but i get very little or no heat. after sometime it will get warm but not enought to warn up the car. any hepl??


This is most likely low coolant level. Have you checked? When the level is too low, hot coolant doesn't circulate through the heater core. If you top it off, it should be throwing heat again. Keep an eye on the level, you may have a leak somewhere. If this isn't it, let me know so I can try to help further.
