I have a 320i. The car seems to run very well with no leaks and noises. But recently the car started to overheat. The temp gauge goes to the red when in idle position or whilst driving. I have checked the water level but seems to be fine plus the fan is in good working order. But sometimes, the temperature goes back to normal and stays in the middle, but more often goes to the red. As well as this problem, my car heater does not work. The fan blows cool air but not hot air. Plus on the fan speed, speeds 1,2,3 does not work but number 4 works. Another problem which just started is stalling whilst in motion or idle. Can it be the battery or the started motor. Can any one help. Thanks a lot
