Question about 2003 BMW X5
The fan only blows cold air. I have replaced the hedgehog (FSR) as it did not blow at all at one point. I have also replaced the water heater valve, twice with used parts and not sure if they are working properly or if it is another problem. before I changed the valve it would get the tiniest bit of warmth come through eventually but only on one side of the car, now 2 valves later and I get nothing at all. Any ideas? The temperature gauge moves nicely up to the middle and stays there...
Andy, it sounds to me like your blend door between AC and Heater core is not functioning. Check that you are getting vacuum to the inside of the car thru the firewall from the plastic vacuum reservoir first. If you are, most likely would be at the dash lever/buttons not sending vacuum to said blend doors/flaps.

It is the Final Stage Unit/Blower Motor Resistor - changed mine and the problem never came back. After two tows and drained batteries. Most mechanics don't seem to put this one togther - you have to demand it. Funny because it is a VERY COMMON problem in BMW.

Go to your idrive., climate the vent settings. you will see a person along with vent areas on the side.
If this persons color is blue it blows cold air so turn the dial for vent closest to that person until the
color changes red then hot air comes out on the vents for driver and passenger. Then let me know.
