2003 Chrysler Town Country Blend Door Actuator Locations

This is most likely being caused by a defective air temperature control blend door and or actuator. This part moves back and forth deep inside the HVAC ducting to divert air across the Heater core or the AC Evaporator core, when they fail or stick they can create this issue.

The most likely problem is either the blend door actuator or a broken blend door itself.
Both are only accessible by complete removal of the instrument panel(dash).
The blend door actuator can be tested with a Chrysler factory scan tool hooked up to the DLC(data link connector). If blend door actuator is working when tested with the factory scan tool, then blend door itself is at fault.
The only other way to test the blend door actuator is to test for 12v at connector, but you would have to remove the instrument panel in order to gain access to the actuator

Usually a sign of a faulty blend door actuator under the dash. The blend doors direct air thru the heater core and vents.

sounds like the actuator. I had the same problem. Mine got to the point where it will now only work with the key. Had it looked at by dealer.. actuator is bad. Good luck.

sounds to me like a blend door problem or blend door actuator problem
