    I have a 1990 740 GL wagon. It now has 320,000 miles and runs great.
    However, the cruise control doesn't work. Could it be the switch, how do I
    check this, I'd like to fix the problem.

  2. First place I would check is the vacuum hoses. Bill

  3. Hi!

    I had a similar problem on my '89 740. Cruise would work if I held in the
    speed set button. On the brake pedal there is a vacuum release valve of
    some description, it was leaking and causing the cruise to reset as soon as
    you let go of the button. I think I rotated the valve/switch a couple of
    times and its sealing again.

    Hope it helps.
