    95 sls n* solenoid clicking

    Hi
    I have a '95 SLS and The solenoid(I think that is what it is) in the picture 6831 is making a clicking, actuates and di-actuates while the motor is running. It is located under the Cruise control servo(picture 6832). Could anyone tell me what this is and why it may be clicking?

    Thanks Ed

    No one know's what this is? Is it just because of the picture? I can try to take another to make it a little clearer.
    Thanks Ed

    Someone with a '95 will chime in.......but take a picture showing a bit more area - that first two still make it hard to locate the solenoid/valve/mechanism.

    Is there vacuum connected to that piece, or just an electrical connector ?

    The engine is a 4.6L Northstar, right ?

    Hey guys
    Here are a couple of pictures further back. It is in the circle. It clicks for the first 5 minutes the car is running then seems to quiet.

    Thanks Ed

    Cruise control module? Is there a cable on it that runs to the throttle?

    I think if you look in the first pictures it is below the cruise control module?

    I give up. Can't recall anything like that on my '97 and certainly nothing like that on my '03.

    Here more better pictures:




    Has something to do with the throttle. Look like you can adjust the idle control speed with a wrench. Could it be idle control module/motor?
    Ok I know, its an idle control valve.

    Re: 95 sls n* solenoid clicking

    Thanks gentlemen.
    Any idea why it would click or tick? Is it supposed to while the car is warming up?

    Thanks for the info.

    I'm guessing it is failing. Does it ratchet when shut down. That is a symptom.

    Hey Ranger
    I'll have to check when I get home.
    What does this do? I assume it controls the idle speed? And when it fails what happens?

    Thanks Again
