Based on the systems affected by this code, we will most likely start with:
B0365
ŚredniFault code B0365 means a low signal level in the air conditioning control selection switch circuit 11 (dual zone). This is a fault related to the Body Control Module (BCM) and HVAC system.
OBD-II error code B0365 indicates a problem in the air conditioning switch circuit for one of the zones in a vehicle with a dual-zone HVAC system. It most often manifests as a lack of response from the climate control panel or incorrect airflow operation. The cause can be a faulty switch, defective wiring, or the body control module (BCM). Accurate diagnosis requires a specialist scanner and checking individual system components.
Symptoms
Air conditioning not working or working incorrectly (e.g., no response to setting changes, no airflow in one zone). The check engine light or HVAC fault indicator may illuminate. Sometimes the fan only works at one speed or does not start at all.
Possible causes
- Faulty A/C control selection switch (button/panel) - Open or shorted electrical circuit (low signal, short to ground) - Corrosion or damage to plugs and connectors - Faulty BCM (Body Control Module) - Faulty blend door actuator motor
