I have a 2006 E-150 van with the 5.4. My speed control failed.

Not all at once, mind you, but first the light on the instrument panel wouldn't illuminate - the speed control continued to work fine. It just didn't tell you it was on.

Then later - maybe two or three months later - it started disengaging unbidden. Then shortly it wouldn't work at all.

Being a good (really good!) parts thrower I replaced all the switches I could. Steering wheel. Brake master cylinder. Speed sensor in the differential. No change to any of the symptoms.

So I took it to the Ford place. They have a sooper-dooper diagnostic computer that probably costs more than the car. Just for the speed control!

They replaced the master cylinder switch I already replaced. No luck.

They replaced the PCM. No luck.

They replaced the clock spring. No luck.

They kept it four days; they gave me a loaner car. Today they gave it back still inoperative.

Anyone got any ideas?
