Have a weird one for you guys, want to see if anyone has ideas.
Have a 2006 Accord EX with 118k. No real problems of any kind, best car to this mileage I've had yet.
Recently started noticing a noise, seemingly emanating from within the dash directly in front of the driver's seat, like behind the instruments. It is a strange gurgling/crunching/mechanical clicking sort of sound, quiet enough that normal road noise or the radio drowns it out but loud enough to be quite obvious when idling. The noise is inaudible from outside of the car or from under the hood.
It seems that it might be related to the AC setting - when I set the AC to fully OFF, it will persist for about 30 seconds, then the noise stops. If I turn the AC back on, the noise returns in within a similar amount of time. It does not change with fan speed, which vents are selected, or auto vs. manual settings.
The AC works fine, no problems at all even in the 100 degree temps we had recently.
Any ideas? Given the behavior I wonder if it's something weird happening with the evaporator, but the crunchy/clicky aspect of the sound makes me think of something like a blend door or actuator of some kind going haywire.
