Hi everyone, I need some help. Maybe someone has experienced a similar problem. I recently replaced a pipe in my car’s AC system that carries freon. After refilling the system, the air conditioner only blows cold air when the car is running fast or for a longer period. When I stop, it stops blowing cold air.
I checked the system and noticed two sensors showing abnormal readings:
B12/2 (temperature and pressure sensor): 9 bar and -99°C
N70b1 (cabin air temperature sensor): +97°C
I also noticed that when I press the AC button, the radiator fan does not turn on. However, if the engine gets hot, the fan works.
Does anyone have any idea what might be causing this?
