New to the whole forum thing. I have tried to have a search so apologies if I'am repeating.
I have 2007 e92 325i se and the heaters are only giving out cold air. It doesn't matter what temp it's set to still freezing. Hot cold dial set to red still freezing cold.
When the car is idol the temp gauge goes up and it blows warmish air but once the car is moving the temp gauge drops and blows cold air again. I have replaced the thermostat and anti freeze but still no joy. Engine is getting up to temp all pipes etc hot just not the bloody blowers. Any help much appreciated
