    Have a pronounced rattle/buzz on initial acceleration or deceleration. Sounds like it's in A/C vents. Only lasts a couple of seconds.
    It's in both 2007 cars.
    Cleaned both A/C filters ( they sure needed cleaning) but no help.
    Any ideas ?
    Thanx,
    Carl

    buzzing is the compressor for the brake recharging/resetting. not sure about the rattling. listen to hear if it happens at stops as well.

    jbdan-our buzz/rattle are not going over bumps, bad road etc. It happens only when starting to accelerate, or when lifting off throttle to decel. short duration, not again until a new cycle.

    psikot--I know that sound, not my "problem sound".

    Thanks for suggestions.

    My gues is some small particles like sand in A/C ducts. Kinda sounds like something small vibrating on plastic. We live near the beach so plenty of sand around.

    Not really a big deal but since it's happened with both cars it would be nice to try to find the cause.
