Billy E46 Posted December 7, 2018 Report Share Posted December 7, 2018 (edited) Good evening all, I drive a E46 330 ci Msport and I came across this strange fault recently, I would like a bit of technical advice on this, as per the title, this is an intermittent fault, the blowers are spinning fine and the dashboard controls all functioning fine and the blower spins to the speed levels, however there seem to be no air coming out of the vents, i am struggling to diagnose what could be the problem, has anyone come across this issue before and what could be the part that's gone wrong? appreciate all your help and advice many thanks B Edited December 7, 2018 by Billy E46 Quote Link to comment Share on other sites More sharing options...
kirkynut Posted December 18, 2018 Report Share Posted December 18, 2018 Try changing the Final Stage Resistor in the driver's footwell above the pedals, YouTube it. It's often known as the Hedgehog. Kirkynut Quote Link to comment Share on other sites More sharing options...
momo Posted December 18, 2018 Report Share Posted December 18, 2018 Isn't there a flap in the heater box that opens up when the heaters are on? Could be stuck.. Or could be the actuator motor that's failed.. You haven't had a double-din stereo conversion done have you? Quote Link to comment Share on other sites More sharing options...
