yo! its possible that one of the gear's deteriorated. seems to be more common with FL..

there was a thread here about it..

if you can get someone to 3D print it, or someone with a cnc lathe

Another thing, ive just checked this "black box" which is this vent control box and all wheels looks like new, all teeth are in perfect condition, what else can be?

I have a similar problem, I don't get either aircon or heated air even though they did work fine been told to check the channel actuators if these stop working the flaps don't move to direct airflow to where and what you want. Could be the same for you?

@The Borg or anyone else have an idea where the channel actuators/flaps are or what they look like? Same issue here.

Any info would be helpful - just so I know what to look for when I pull it apart. I'd be happy to just have the vents set to permanently be on the face. Currently they're permanently on my feet :(

I'm hoping there's a manual adjusment in there I could do to set them to the face vents.

AH, the flow adjusters or what ever their called. I'm not sure the parts I replaced are the same. The actuators I replaced change the vent flaps that adjust what air flows from what unit either heater or aircon or both. They may be the same I'm not sure. Ones located on the left passenger well, another dead center that you will need to remove the center console to undo one bloody screw O_O and the third is in the drivers well ( can be seen through a web of wires ) Hope this helps

Does anyone know which component controls the vent selection? The Borg's post is helpful but I'd rather not pull out three different components if I can just pull out one.

From what I've read through this and various threads it seems people either have problems with the flaps not changing from Heater to Cold or the flaps not changing from Face/Windscreen/Feet vents etc.

It's unclear if the same box is the cause of both or not.

I’m having the exact same issue as Cameron, AC just stayin on feet/windscreen, have disconnected/reconnected the unit itself to no avail.
Does anyone know which box controls the air path?

I'm going to have a look at mine Wednesday but it seems to be the middle part in this pic:

I'm hoping it's this white arm on the right that mechanically controls the vents

While we're discussing climate control, does anyone know why it's obsessed with "fresh" air?

Anyway to have it on recirc AND auto?

This drives me insane!

Had to pull black box apart a few months ago , for the same reason , a broken tooth off one of the cog spindles stopped it from rotating , just be gentle separating the halves .
