Hi

I'm new on here, and I really hope somebody can help me.

Basically, I've got a 2008 (old shape) Mk6 Fiesta, ztec climate, 1.25.

Anyway, last week I started having a problem where I would turn the dial to move the fan / heater blower direction to the windscreen, feet, face, etc, and it would just click and not actually change. it works some of the time and just gets stuck then.

So I investigated, unfortunately its not the springy cable thing that's at fault. I traced it back, and there's a white cog... which connects to a black cog... that has somehow gotten damaged.

please see the photo. its the black cog on the left.

does anyone know how I can replace this cog? what is the part called that it goes into?

Ive been told I might need to replace the whole entire part... but I've got no idea what the part is called, I've googled until I'm blue in the face!

Anyone with any idea about this I'll be so grateful for any advice! thanks.

Just find the same car on fleabay, such as type in 08 Fiesta 1.25 and ask the breaker to take the whole part out and change that, should only be about £10.

I don't know if this video makes it any clearer.

The assembly is the Heater Core Housing.

Very unlikely that you can replace the gear in situ and its a big job to remove and replace the housing.

The gear is a bevel gear.

As already suggested try and obtain another housing and see if you can find a way to replace the gear without having to remove the assembly. Found this one on ebay

Thanks so much for replying.

I was gonna buy that thing in eBay. But when I put my car details in, it comes up saying it will not fit my car?

The seller has only shown the 1.4 engined versions of the Fiesta as being compatible. The question is whether that housing fits the 1.25 engined versions as well. I cannot think of any reason why they would differ unless anyone knows different?

I would have thought its the same for all models petrol diesel mk6 and 6.5.

The picture of the gear looks identical
