Solved the AC vent rattling noise issue in my Maruti S-Cross with a DIY

After opening i was searching to see any hanging coupler which was making sound or any frame but everything looked good.

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:

After the vents were opened:

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.
