C220 W203 no air blowing through vents

[Dan ban]

Hi all, replaced my heating blower this morning and I can hear it blowing but nothing is coming through the vents. Any ideas please.??

It might be needing a reset; try cycling through windscreen, vents, floor, etc manually to see if that helps.

Do any of the lights work on the heater module? Recirc etc?

Hi all, thanks for your responses, I'll try resetting the flaps tomorrow, I done this earlier but the hearing was on and in the video it says turn everything off. I have a digital display so maybe different to that video???
Yes all buttons etc work perfectly but no air is coming out of any vents.

How do you reset flaps on a digital system Please.

Hi all, I have a digital unit and not the old type so that method don't work any other ideas please?

Your car is presumably post-2004 then, so your display will be different from the one in that video.
That reset procedure only works if the air distribution controls were working before your blower replacement. It will not repair faulty flap operation caused by sticking flap motors.

Yeah I got a c220 2012. Thats what I don't understand, it was all Working perfect and all I done was change the blower and now it blows but don't come out of the vents.

To be honest, I think it should be blowing more than it is, iv then the box off under the bonnet and can feel it blowing.

Thanks. When you installed the new blower, did you go for like for like. What brand is the blower.?

Hello! Did you get to the bottom of this? Weirdly just changed my radio now no air from front vents but can hear the motor no problem. Thanks
