These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Did a search but no real answer... When my air con is on I'm getting a rythmic clicking from the front left dash area. Like a fan hitting or rubbing. Not loud but still annoying. Any ideas? Could be a warranty issue? I don't want to take it to an OPC if it's not a warranty fix. They'll just charge me and waste my time, rather go to an Indy. Thanks... :thumb:

POST 2Original post

Not sure if it is the same problem but I had a rattling coming from what sounded like inside the dash. It turned out to be the carpet boards in the foot well which a simple kick fixed

POST 3 / ORIGINAL POSTEROriginal post

It's definitely a mechanical sound and disappears when I turn the air con off...

POST 4Original post

A warranty issue for sure. Does the frequency of the ticking alter proportionately when you change the fan speed? There are only three things A/C related under the dash that could do this: Fan (sometimes called blower) Vent control flap / film (this directs the air flow according to demand and other variables and is moved by a servo motor) Evaporator expansion valve

POST 5 / ORIGINAL POSTEROriginal post

Not to my knowledge, it's constant regardless of fan speed...

POST 6Original post

Is it coming from the passenger side air vent? The interior temperature sensor is in the vent housing, just below the vent grille, and it has a small fan to draw air across the sensor. Might be that.

POST 7 / ORIGINAL POSTEROriginal post

It's from that area so could be that. Is there a way of actually getting to it?

POST 8Original post

You would hear it if you put your ear next to it. Easy to get off - just 3 screws: (LHD car shown).

POST 9 / ORIGINAL POSTEROriginal post

Thanks Richard, I actually think the noise is coming from near the front of the dash, closer to the windscreen :?

POST 10 / ORIGINAL POSTEROriginal post

Ok, update, I've traced the noise to the fan behind the pollen filter. When you take the filter out there's a motorised flap and then behind that is a fan. It's the fan that's making the noise, anyone know who to get at it and possibly fix/ tighten? Problem is when you turn the fan off to inspect it the motorised flap closes... :frustrated:
