Cooling Fan Runs while car is off
Came home the other day and wife's 2010 C350 cooling fan was running.The car had been sitting idle for about 10 days.I started the car with no problem and the fan shut off when I turned the car off.When I tried to start the car the next day the battery was dead.mechanic shop checked all codes and no issue was found.Any thoughts on why the cooling fan would just come on by itself??
