Seems like a drastic course of action given that you are not sure where the noise is coming from. You may find that the rattle does not come from there, AND that you will have introduced a new one when putting the console back!
Any chance you could get someone else to drive the car while you move around from one seat to another trying to find the definitive source of the noise?
I have an annoying rattle in mine which I thought came from a front speaker, or an air vent. Took me days to work out that it came from the cowling over the rev counter (still not fixed... not sure what to do).
With regards to your comments, it may not have anything to do with the hearing duct, but more with the noise frequency/vibration that changes as the engine warms up.
Have you checked:
- the cup holders compartment (cup holders themselves and the compartment lid). Does it make any difference if the compartment is closed or open?
- the console lid and its open/close switches? Does it make any difference whether the console is closed or open?
- there should be a removable plastic insert within the console. Have you checked that there is nothing wedged underneath it like a coin? Have you tried taking it out (it just pulls out)
- Is the lighting within the console working (I think there is an orange lilght within the console and a blue one within the cup holders). If it is not, maybe one of the little bulbs has worked itself loose
- Have you tried sliding the console back and forth to check that nothing is wedged underneath? Does the rattle increase/decrease depending on the position of the console?
CAn't think of anything else...
