B0441 Chevrolet Code - Left Air Temperature Actuator

Quick Answer

The Heating, Ventilation, and Air Conditioning (HVAC) Control Module commands the left air temperature actuator movement with one of three voltage signals applied to the left air temperature door control circuit. Common causes include Faulty Left Air Temperature Actuator, Left Air Temperature Actuator harness is open or shorted, Left Air Temperature Actuator circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code B0441 Chevrolet Description

The Heating, Ventilation, and Air Conditioning (HVAC) Control Module commands the left air temperature actuator movement with one of three voltage signals applied to the left air temperature door control circuit. A low voltage of zero volts moves the left air temperature door toward full cold. A voltage of 2.5 volts stops the door. A voltage of 5 volts moves the left air temperature door toward full hot. The HVAC control module determines the current position of the actuator by monitoring the feedback voltage of the left air temperature door position signal circuit. The feedback potentiometer position is a function of the actuator position. A high voltage indicates a full cold left air temperature door position. A low voltage indicates a full hot left air temperature door position. The HVAC control module controls the left air temperature door position in order to maintain the selected air temperature.
Whenever the HVAC control module keep alive memory battery power is interrupted, the HVAC control module will perform a recalibration of the actuators. During recalibration, the HVAC control module will drive the actuators to their minimum and maximum travel extremes. The HVAC control module will then calculate a travel range from this data and compare it to a calibrated range within the HVAC control module. If the actual travel range is not within the calibrated expected range, the actuator will be considered not calibrated and the DTC will set.
