DIY: Stopped the AC vent rattling noise in my Maruti S-Cross

Hello All,

Few days ago I started observing a rattling noise coming from the center console area of the dashboard (Central Ac Vents / Infotainment System).
The strange part was the sound was not constant rather it was intermittent, hence it became hard to find exactly when it was occurring.
I started noting down the conditions which were triggering it, mostly it was on 3 occasions -
- When i was driving at lower speeds while at higher gears: like uphills, flyovers, at some traffic conditions etc. [Intermittent]
- When one of the tyres hit the reflector plates on the road partitions at medium speeds. [Intermittent]
- On bad patch roads or continuous small speed breakers. [Intermittent]

I decided to open the central console section and started searching for articles/videos around it. Took following two references -
  1. YouTube reference :
  2. Leoshashi's thread on similar issue :

Sharing few images of the work below -

After opening i was searching to see any hanging coupler which was making sound or any frame but everything looked good. On a sad note I was about to repack everything then I saw the AC vent section. I tried to shake the left one, there was no sound; it had a good space to avoid hitting the surrounding portion.

I tried the same approach on the right one, BINGO I have the culprit !!

Same sound when you shake the right one. It was hitting the dashboard when I was shaking it.

I added extra foams around all the sections of the vent and re-packed everything. I wrapped paper tape on all the locks and tied up some wires to avoid future rattling.

Infotainment check before final packing -

Repacked -

1 week observation - No sounds on all the three conditions observed above. So far so good.

Note - Re-packing of AC vents needs a bit of trick and hard. Be careful around it.

Thank for reading

Excellent job. I hate rattles, they just drive me nuts. I will take my whole car apart to find and fix a rattle.

Just a bit of advice, when you start taking bits of trim of the dashboard you should consider disconnecting the battery.

Thanks Jeroen, I had that in back of my mind as prerequisite and somehow missed it. Will follow this for sure next time, if required.

Re: DIY: Stopped the AC vent rattling noise in my Maruti S-Cross

The timing of this post couldn't have been better. Been having this maddening low rattle with identical symptoms for almost a month now on my 2017 scross, more noticeable since I mostly drive with windows closed & engine for music...
Checked and tightened every screw I could spot starting with the tweeters, glove box and everything to the left - thats were it seemed to be coming from. Surprising how many screws and press-fit items were somewhat loose, but no matter what I did, the noise persisted. And the sympathy filled 'poor guy's gone off his rocker' reactions from others while I fretted over a non-existent rattle didn't help.

Never thought of opening up the AC vents - weekend calendar blocked
