Temperature controls not working, stuck on eco mode, seat heater not working...
Temperature controls not working inside the cabin, stuck on eco mode, seat heater not working, as well as the radiator fan going on at full speed constantly. I just recently installed an android head unit, but even after going back to stock comand, I couldn't resolve the problem. Any ideas?
Best regards,

Eco mode is a default if the ac system is low on refrigerant, or the line pressure sensor is bad, but you've got the seat and fan issues too. Are you able to scan the vehicle modules? You'd need a scantool beyond a basic obd2 scanner.
The reason I ask is because sometimes a malfunctioning front or rear SAM can cause issues like these. The malfunction doesn't mean the SAM may need replacement, it could be a power/ground circuit minor problem. But a scantool like icarsoft, etc is needed to communicate with the vehicle modules.
There's also the possibility that you may have inadvertently messed up a connection somewhere with the Android install. Happens sometimes.
