Re: <e34> High Pitched Noise - Help

["Ken Cory" <kcory@xxxxxxxxxxxx>]

Just a thot.  I've heard of these models making some strange noises from the
a/c heater system opening/closing flaps, even after the engine is shut off,
though it hasn't done it in mine (yet).  This could happen even though
you're not using the a/c component of the system.
