2001 Concorde whistles at 60 mph

    In near-cold temperatures, (30- 40) here in the south, and through fog
    banks, sometimes, I hear a loud whistle coming from engine compartment.
    Constant pitch. Goes up 2 notes at 70.

    Car passing from opp direction will cause it to weaken, temporarily.

    Is speed-related, not rpm-related.

    Used to have this problem with two K-cars.

    What's causing it?

    That noise is typical of the LH cars if the window glass is loose in the
    tracks. Recently my '99 Concorde was making a whistling noise that I
    couldn't pinpoint (high frequency sounds are hard for the human ear to
    determine direction on). A few days later the window glass came out of
    and bound up in the track due to a slight misadjustment of the regulator
    arm (inside the door). If you think I'm on to something, pull the door
    panel and look at the regulator arm vertically-slotted screw hole. If
    the screw is not bottomed into the slot, make sure the glass is in the
    track and loosen that screw, push the arm downward, and tighten the
    screw to secure it at the bottom of the slot.

    You might also check into TSB No. 23-07-00 ("Wind noise heard in
    interior"). It only is supposed to apply to '99 & '00, but it wouldn't
    be the first time a TSB should have applied to a broader range than what
    they claim.

    Not saying that the above will nail it, but maybe...

    I was thinking of the whistling noise as being a relatively high
    frequency. I just know that when mine was "whistling", and when I had a
    high-pitched whistling noise from the brake booster on an unrelated
    problem, it was hard to tell direction of the source of noise. Maybe
    that isn't generally true.

    After your e-mail, I thought of another likely possibility: Though I
    haven't had the problem on my Concorde, the LH cars have a big problem
    with the door gaskets shrinking and pulling away at the corners of the
    body leaving an air gap between the door frame and the body when the
    door is closed. Discussed a lot on the 300M Enthusiasts forums:
    http://300mclub.100megs42.com/forums/index.php - look at the "Black Trim
    and Weatherstripping" forum. Look there for more insight and solutions.

    Yep, this happened to me. The driver's side rear door shrunk on my '98,
    and it whistled something awful. If you want to try it, I had good luck
    re-stretching the gasket and then using a 3M adhesive product especially
    designed for door seals. The repair has held for several years now.
