curise control component location question

    At the moment all I have is Chilton's (which might as well be
    "Chitlins"). In the 240, I was wondering where the vacuum servo is
    located (the diaphragm unit that actually pulls on the throttle)? Is
    it in the passenger compartment up under the driver's-side knee
    bolster somewhere (I hope) or is it in the engine compartment like the
    960 (where it would be a missing component in my car).

    TIA!

    There are several different types of cruise control. The older types
    (which shouldn't apply to your car) have the servo under the hood. The
    newer types (should be your type) have the servos under the dash.
    Remove the knee bolster, follow the vacuum hose from the brake pedal
    vacuum switch.

    Thanks for the reply, Mike.

    That must apply to the 240's. The '93 960 has it under the hood... I
    saw the vac line under the hood and it does go through the firewall.

    Yesterday I might have found one possible cause of it not operating. I
    noticed that the clutch pedal has 'slop'- that is, the pedal is not
    held up all the way like a spring is broken. It might be allowing the
    pedal to 'hang' down just enough to activate the clutch's cut-off
    switch for the cruise and keep it from engaging. I have a Bentley
    repair manual coming for it on Monday, so the investigation will begin
    then.

    As it turns out... I was cleaning the car up, going through this and
    that. I was lubricating the front seat slides, and since I was down
    there i turned around to look up under the bolster. It was then I
    noticed that the spring for the clutch pedal was either weak or
    misadjusted because the clutch pedal is sloppy- having some sloppy
    free play.. Hmmm....

    So when on the road today I held the pedal up with my left foot and
    engaged the cruise, and it worked perfectly, disengaging as soon s I
    released the pedal to it's abnormal, at-rest position! :)

    What my first sentence should have read: "There are several different
    types of cruise control **on 240s**."

    As you read in this thread, I found that it works fin except for the
    "floppy" clutch pedal that was disengaging the cruise function 100% of
    the time. But I think I found the solution! I adjusted the clutch.
    With the proper clearance at the tranny as specified in the shop
    manual the pedal now is held at the top of its travel and I can hear
    the switch disengage and reengage when pressing and releasing the
    pedal. Haven't driven it for as test yet, but I think it is now OK.
    Will comment on the previous shop's maintenance after a test ride.
