Chrysler Sebring Convertible 2007 with 2.7L the mode and blend door actuators give errors but do turn on selftest modus on ATC. The error shown on display are 4 items, 23, 24, 32 and 33: 23: Blend door actuator feedback failure (bad servo) 23: Blend door actuator feedback failure (bad servo) 24: Mode door actuator feedback failure (bad servo) 32: Blend door actuator stall failure (stuck door or bad servo) 33: Mode door actuator stall failure (stuck door or bad servo) The actual problem is that in practice the mode door and blend actuators do not function. Can anybody give me a hint? Regards. Peter.

Question edited for clarity.

The videos should help. They are pretty much the same for all Chryslers.

Wiring, schematic, electrical diagrams, fuse diag, error codes etc are basic contents of these online books they have here on this website www.reliable-store.com I have attached. Must check it out

blend door actuator not working

1 - Blend door actuator 2 - Mode door actuator 3 - HVAC wiring harness

While it's possible there are other problems the repair procedure would be to replace the blend door motor and while doing so confirm that the blend door moves freely without binding up.

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

Hi,
This may be similar to what I just fixed on an '00 dodge:

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)
33: Mode 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)
44: Common door shorted to ground (probable wiring fault, could be a servo that failed in an odd manner)
45: A/C control blend door input open or shorted with respect to ground (MTC only, wiring fault or bad servo)
46: A/C control blend door shorted to battery (MTC only, wiring fault or bad servo)
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)
50: A/C control electric backlite (EBL) switch fails (MTC only)

51: System voltage too low for calibration!!! (check battery cables, battery and alternator!)

Hi,

Chysler HVAC code 23 = Front Mode (Blend) Door - Range too Large.

Possible causes:

- Actuator circuit test faults preset
- Overcurrent faults present
- Mode door or A/C Heater housing components warped, worn, damaged or broken.
- Mode door actuator
- A/C Heater Control (ATC)

HI. Here is the complete line up of specs concerning your vehicles front and rear tires. You did not post the trim line of this car, so I posted all models and tire combination's specified by the manufacture.

Code 23= Blend door feedback control


On cars with automatic climate control: To enter diagnostic mode, set the temperature to 75F, press the the off button. Press Floor, Defrost\Floor, Front Defrost simutaneously for 3 seconds until the temperature display begins to flash.
On cars without automatic climate control, set the blower to any speed, turn the temperature control in between warm and cold. Press Floor, Defrost\Floor, and Front Defrost. All codes will flash via the Front Defrost button.
When the test is over all fault codes will be displayed (on cars without automatic climate control, they will be blinked out on the Front Defrost button).
Code Action
23 Blend door feedback control
24 ATC mode door feedback failure
25 Ambient temperture sensor failure
