B0361 Code - Left Actuator Feedback Short To Ground

Quick Answer

The Heating, Ventilation, and Air Conditioning (HVAC) Control Module commands the air temperature actuators to move by controlling the voltage supplied on the control circuit. Common causes include Faulty Left Actuator, Left Actuator harness is open or shorted, Left 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 B0361 Description

The Heating, Ventilation, and Air Conditioning (HVAC) Control Module commands the air temperature actuators to move by controlling the voltage supplied on the control circuit. A signal voltage of 0 volts or a signal voltage of 5 volts rotates the air temperature actuator. A voltage of 2.5 volts stops the door. The HVAC control module determines the current position of the actuator by monitoring the voltage on the signal circuit. The feedback potentiometer is a function of the motor position. The HVAC control module controls the air temperature actuator door positions in order to maintain the selected air temperature.
