Hi all. My 2014 Yeti makes an intermittent/nuisance buzzing sound when the climatronic is set above 20°C. I’ve tried doing the climatronic recalibration on the panel buttons but it doesn’t resolve anything. I’ve dived in to establish where the fault actually is and can hear and feel the buzzing coming from whatever this is that I’ve circled in the pic. Further access to this area seems major work and I’m guessing it will involve the entire dash removal as starters. Any thoughts? Any ideas what this part is called?

View is taken down through the removed centre vents and is to the right of the back of the stereo.

Hi, welcome.

The boys and girls on the Yeti forum would possibly know, you could ask there or you could have a look at the threads and posts there. - Škoda Yeti - https://www.briskoda.net/forums/forum/170-%C5%A1koda-yeti/

HTH.

Welcome.

Hopefully someone can help.

Personally i would set it to 19*oC and leave it like that.

The weathers hot is it not?

You could give that area of white part a little spray (shake can first) of GT85 and see if the noise reduces which might indicate you're in the right area.

Thanks all. I’ve sort of now given up on this and just resigned to an interior set to 19°c and rely on the heated seat for any sort of warmth. 🙁😂

19°C and heated seat are you driving in just your underwear. 🙃

Heated anything takes a fair bit out of the battery, you may be fortunate and not have start-stop or a recent(-ish) new battery but if not you might want your charger maintainer ready for preventative rather than reactive recharging.

If you've got a vacuum cleaner that blows as well as suck (hose to exhaust outlet) then a quick blast of air might dislodge any debris/crud/broken-bit that is there perhaps causing the transmission of the vibration noise.

I bought a £30 Lidl vacuum cleaner just for the blow outlet and use it to better clean out a lot of items - but it's best done outside and careful not to be too close, concentrated, forceful in more delicate situations, like with a power washer, and never let go of the hose or it can go wild. I used it to blow off some surface rust I'd wire-brushed off from the underside of a neighbour's car and even though I was back a bit I wished I'd put goggles on. Made cleaning the "drive" of rust dust very easy though. Also good for back-blowing out other vacuum cleaner filters too.

I’ve since noticed that when the climatronic system isn’t doing its buzzing noise, hot air only comes through the passenger side when all controls are set for it to come through both sides. After further research on the net it seems that the fault all points to a faulty blend/flap actuator. Images of the part also look consistent with the one I photographed in situ.

If it's one side then yes it points to a flap on that side or what ever moves the flap or the mechanism, buzzing might be it trying to move but not able to. Presumably driver and front passenger are independent for settings.

Are you able to compare your photo with others on the web to see if that white bit of plastic is sitting right or has anything sitting in that grove or that groove runs on something.

You put you've tried the flaps resetting themselves by the unit going through its little dance and recalibrating itself so if the unit won't reset you need to give it a hand to get warm air to your side. Thankfully my wife's car doesn't have this automated system, the standard flaps and mech are bad enough to me without adding in the computers lords and masters to throw their wobblies.

I would have thought this subject has been covered on Briskoda, on other models if not Mk3 Fabias Yeti, a Google search often comes back to a post or thread on this site. I'm not sure getting at the heater and motor is that easy or fun (but then nothing is fun on modern cars as so much is packed into spaces which often aren't really enough.

Other posters may be able to help you though. Good luck.
