Need Help, R56 N12 engine weird Cooling Fan issue
Hi, I have an 2010 r56 n12, 2 wire cooling fan. recently the fan starts normally after it reaches temperature but it never stops unless I turn the car off which then stops. The same applies to the AC, when I command it to turn on, the fan turns on but never stops, even if I turn off the AC. I have no codes.
BTW, Water pump, Thermostat, temp sensor, radiator, condenser, fan relay, everything is ok.
When the engine temp reaches 108 Celcius, the fan starts as it should. After the temp drops to around 80 C, the fan is still on, the temp starts to climb up to 105 and stays there meanwhile the fan keeps running. everything works normally. no boiling, engine working temps normal, except the fan.
In conclusion, If the fan is turned on by either the AC or the engine temp, the fan will stay on until I stop the engine. any idea? Thank you guys
