300M ATC codes 23 & 24

I just experienced a heating system failure in a 2000 300M. The ATC is showing fault codes 23 (blend door actuator) AND 24 (mode door actuator). What are the odds they both failed at the same time? Seems unlikely to me. Could it be something else that they have in common, like the ATC? I don't really want to tear into the console and replace them, only to find that they weren't the problem.

Thanks for any insight....
Mike

I have also developed this issue. Was it ever resolved? Anyone else have this issue? I tied to clean the white connector above the gas pedal, but I could not get the connector unlocked. ;(

What code(s) are you getting exactly?

There is a post on this forum about HVAC recalibration. Try this first. Is a simple diy process. May very well fix the issue.

23 and 24. When the diags run, I hear doors moving. They temp blends just fine. I can get AC or Heat and set a temp, but I only get air out of the dash vents. I never can get air to the floor or the front window.

Thanks,

David

A feedback signal failure can occur on the blend
or mode door. The body control module monitors the
feedback signal to check the position of the actuator.
The body control module not only checks the level of
the signal but also how much the voltage changes.
A feedback failure can occur if there is a short or
open circuit in the wiring, a bad actuator, a bad
body control module, a bad HVAC unit door or
connecting linkage. The easiest way to diagnose
this is to use the DRB to actuate the blend or mode
door. Note that the feedback voltage of the actuator
should smoothly change as the actuator is moved. A
sudden change in the feedback voltage to a 5.0-volt
or a 0.0-volt level indicates the actuator is bad. A
fixed feedback voltage that is less than 5.0 volts or
greater than 0.0 volts without a stall failure, or a
short failure indicates that the actuator, the HVAC
unit door, or a connecting mechanical linkage is
jammed thereby preventing movement. A feedback
signal voltage that stays on 5.0 volts or 0.0 volts
indicates a wiring or body control module problem.
The feedback voltage should always be less than 5.0
volts and greater than 0.0 volts.
The feedback trouble code can also occur from
lack of actuator travel. This can be checked by
confirming that the feedback signal smoothly
changes when the actuator is moved with the DRB.
If the signal is OK, the door travel is not correct.
The actuator must be removed and the HVAC unit
door mechanically checked for proper operation.
Typical problems that prevent door movement in
clude screws dropped in the HVAC unit or warped
doors. Replace any part that is found defective.

I was unable to find a thread for HVAC recalibration with a simple search. I have also tried disconnecting the Battery.

Here's the Calibration procedure:

STANDARD PROCEDURE - HVAC SYSTEM
CALIBRATION
This procedure may be performed on both the ATC
and MTC systems.
(1) Start engine and let run.
(2) If the vehicle has an ATC system, turn the control
head on.
(3) Set the temperature controls to the full cold
position for two minutes.
(4) Set the temperature controls to the full heat
position for five minutes.

Thanks Ronbo, I'll give that a try tomorrow.

Appreciate the help!
