Theory of Operation
The A/C Heater Control calibrates each actuator individually. Automaticcalibration occurs upon power up after
installing a new A/C Heater Control. Manual calibration occurs by sendinga command with the scan tool. The pur-
pose of actuator calibration is to determine the total span of door travel between physical stops. To calibrate the
actuator, the A/C Heater Control first moves the door to an end stop, and then counts the number of pulses it takes
to move the door to its other stop. An expected range of span is stored in the control’s memory. If the measured
calibration value is less than the expected range for this actuator, this DTC will set. Note thatthe control clears all
stored calibration faults at the beginning of the calibration procedure.
When Monitored:
During actuator calibration.
Set Condition:
If the total span of the Mode 2 (Defrost to Floor) Door is less than the low range limit.
Possible Causes
DOOR DRIVER ELECTRICAL CIRCUIT(S)
MODE 2 (DEFROST TO FLOOR) DOOR SEIZED, BINDING, OBSTRUCTED

B104C–BLEND DOOR CONTROL CIRCUIT/PERFORMANCE (SINGLE-ZONE)
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The A/C Heater Control monitors the door driver circuits during actuator operation for shorts to ground, shorts to
battery, and shorts to other door driver circuits. If detected, the A/C Heater Control reports these types of faults as
Control Circuit/Performance DTCs. It is important to note that Control Circuit/Performance DTCs do not indicate
where or what type of short is present and that additional system testing isnecessary to provide more details about
the reported fault.
When Monitored:
With the ignition on.
Set Condition:
If the A/C Heater Control detects a short on any of the door driver circuits while attempting to drive this actua-
tor. This DTC has a maturing time of 5 seconds and a de-maturing time of 10 seconds. If the DTC’s status
changes from active to stored, it will stay in memory for 100 ignition cycles.
Possible Causes
DOOR DRIVER CIRCUIT(S) SHORTED
NOTE:TheDTCmustbeactivefortheresultsofthistesttobevalid.Donotperform this test if the DTC is
stored. Refer to HVAC System Test for stored DTC test procedures.
Diagnostic Test
1.RUN THE ACTUATOR DTC DETECTION TEST
Turn the ignition on.
With the scan tool in HVAC, erase DTCs.
Turn the ignition off, wait 10 seconds, and then turn the ignition on.
With the scan tool, select System Tests and then select Actuator DTC Detection. When the test is complete, select
View DTCs.
Repair
Diagnose and repair the DTC(s). If multiple DTCs are present, beginning with the common circuits, diag-
nose and repair all short high DTCs and then all short low DTCs. Refer to the Table of Contents in this
Section for a complete list of HVAC related symptoms.

CIRCUIT
Disconnect the Blend Door Actuator harness connector.
Measure the resistance between the (C61) Blend Door Driver circuit
and the (C34) Common Door Driver circuit in the A/C Heater Control C1
harness connector.
