I have an issue with my IS 300h 2019.
Climate control buttons not responding, but there is a light on them. Seat heater buttons not responding. Outside temp showing E. And radiator fan is always on, even on cold car.
By now replaced radiator fan sensor and outside temp sensor, nothing changed. All fuses and connections are ok. Got a code U0164 - Lost Communication with HVAC Control Module.
Any help please?
