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...
