Ford Excursion :: 2002 - Cruise Control Would Come On Intermittently

2002 Ford Excursion cruise control inoperable. Problem began when cruise would come on intermittently. I would push the on button then set, at which point the green cruise icon light would either come on and the cruise would set or she would flash and not set. Sometimes holding the switch down worked, other times not. Now no matter what I do the cruise will not engage.

I have had the recall done for the cruise control by the dealership.
I have checked the fuse on the recall module, the 2.5 is in good shape and not blown.

I also found this guide to a self test (copied below). I used the test, turning the key on with the off button depressed yields a green speed icon light. Letting go and pressing on yields a green flash as well. But when I move on to pressing resume I get no lights at all, same if I continue through the other switches, no more lights.

Here is the self test guide -

*cruise control self test

Enter self-test diagnostics by depressing the speed control OFF switch while turning the ignition key ON, making sure the engine does not start and is not running. The speed control indicator on the instrument panel will flash once to indicate that speed control module entered the diagnostic mode. Five additional flashes at this point indicate a defective speed control servo.

Release the OFF switch.

Press the remaining switches in this sequence: ON, RESUME, COAST and SET/ACCEL. If the ON switch is not depressed within five seconds after entering the diagnostics mode, the module times out and the procedure must be started over.

The speed control indicator lamp will flash as each switch is depressed. Press each switch in the sequence immediately after the indicator light goes out for the previous switch. NOTE: There will be a slight delay when the last button is pressed and the lamp flashes.

A lamp flash with the last button (SET/ACCEL) indicates that the static test passed. If the lamp does not flash with the last button and there are no additional flashes of the lamp, the switch is defective. If the lamp does not flash with the last button, and additional flashes occur, follow the chart below for trouble codes:

2 flashes - BPP defective, circuit is defective, brake applied, CPP switch or jumper (if equipped).
3 flashes - deactivator switch is open or circuit defective.
4 flashes - vehicle speed signal is out of range or circuit is defective.

Immediately (.25 second delay) after the static test, the speed control servo does a dynamic test by automatically actuating the throttle lever from 8 mm (0.315 in) to 12 mm (0.472 in) of travel from the idle position. During the dynamic throttle pull, observe throttle movement to witness any binding or sticking of the speed control cable and correct connection of speed control cable to throttle lever. Make sure the throttle returns to the idle position.
