Based on the systems affected by this code, we will most likely start with:
B0325
ŚredniFault code B0325 means a low signal level in the air recirculation mode switch circuit (switch 3) in the air conditioning and ventilation system.
Code B0325 indicates a problem with the air recirculation switch in the air conditioning system – a too low signal in the circuit can prevent proper switching between inside and outside air circulation. This is a typical electrical fault requiring diagnostics of the wiring and the switch itself. Contact a mechanic to professionally check the ventilation system and restore driving comfort.
Symptoms
Air recirculation mode not working correctly; inability to switch between outside and inside air circulation; recirculation button indicator may not respond or may flash; reduced air conditioning effectiveness.
Possible causes
Faulty air recirculation switch (dirty, worn contacts) Broken or shorted wire in the signal circuit Corrosion on wiring harness connectors Faulty A/C control module (less common) Blown fuse responsible for the A/C system

Does code B0325 require professional diagnostics?
The code alone is not enough. To find the cause, you need to read live data, check freeze frame conditions, and compare with vehicle behavior. Book a diagnostic session.
