'99 24v cruise control

[shorod]

Odd. My Ford service manual CD for the 1998 model year (I don't have the 1999 manual) references it as a clockspring assembly in the wiring diagrams for the cruise. Not a bit deal though....curiosity more than anything.

One thing you may want to confirm is that the cable assembly to the throttle plate is in good shape. I had a somewhat similar experience on my old '88 EXP that started out as the cruise dropping out on steep hills. Eventually it got to the point where when I tried to activate the cruise I'd get a quick flash of the cruise indicator on the instrument cluster, but the cruise wouldn't actually engage and the light would stay out. That turned out to be due to a broken nylon piece that connected the servo cable to the throttle plate. The cruise was not able to maintain speed so it would shut itself off. I replaced the cable assembly and all was well (couldn't buy just the nylon piece).

Since you too get a flash of the indicator and the self test passes, it sounds like an input to the servo is likely the issue rather than the servo itself.
