What Does B0365 Mean?
This code indicates the Body Control Module (BCM) has detected that the feedback signal from the right-side actuator is shorted to ground. The actuator could be for HVAC blend doors, door locks, mirror adjustment, or seat positioning depending on vehicle configuration. The BCM expected a variable voltage signal from the actuator's position sensor but is instead reading near 0 volts, indicating a direct path to ground in the feedback circuit.
Common Causes
40%
Damaged or chafed wiring harness causing feedback wire to contact ground or chassis
30%
Failed actuator with internal short circuit in feedback potentiometer or position sensor
20%
Corroded or damaged connector pins at actuator or BCM creating ground path
10%
Failed Body Control Module with internal short in feedback circuit driver
Diagnostic Steps
1
Step 1: Perform visual inspection of the right actuator wiring harness from actuator to BCM, looking for pinched, chafed, or damaged wires, especially where harness passes through body panels or near moving components
2
Step 2: Disconnect the right actuator connector and measure resistance between the feedback signal wire (consult wiring diagram) and ground with a digital multimeter; should read infinite resistance (open circuit). If reading low resistance, trace and repair short in harness
3
Step 3: With actuator disconnected, back-probe the BCM side of the feedback circuit and measure voltage; should read approximately 5 volts reference voltage. If 0 volts, suspect BCM internal fault
4
Step 4: If wiring tests good, connect a known-good actuator or measure resistance of actuator feedback potentiometer through its range of motion (typically 500-5000 ohms variable); replace actuator if resistance is 0 ohms or does not vary smoothly
5
Step 5: Inspect both actuator and BCM connectors for corrosion, bent pins, or moisture intrusion; clean with electrical contact cleaner and apply dielectric grease if corrosion found
6
Step 6: Clear codes, operate the affected system through full range, and verify repair by monitoring live data for proper feedback voltage swing (typically 0.5-4.5V) and confirm no code returns

The most common cause of B0365 (Right Actuator Feedback Short to GND) is: Damaged or chafed wiring harness causing feedback wire to contact ground or chassis
Typical repair costs for B0365 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This code does not affect vehicle safety or driveability. The affected comfort or convenience feature (HVAC door, power seat, mirror, or lock) may not function properly, but the vehicle remains safe to drive normally.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B0365 to identify the root cause.
