I just fixed my Cruise control problem. It didn't work at all, no light in the dash either. What had happened was, I had changed the brake booster some months back and when the brake pedal is disconnected from the booster shaft, it allows the pedal to raise too high. It will contact the cruise control disconnect switch to the left of the brake switch. To find the switch, look close and there is a "L" bracket welded on the brake pedal and the cruise switch contacts this bracket. Well this switch is a self-adjusting switch designed to be installed with the pedal at least an inch or so depressed. When the pedal is released it will contact the switch and push the shaft into the switch to the determined setting and it will lock into that position. I was able to pull the shaft out enough to make contact again and it self adjusted like it's supposed to and now the system works great! What made me go to this switch was by checking power at pin 6 (blk/yellow wire) at the cruise servo connection. This connection has 6 pins and the end pins (1 & 6) both have 12 volts. Mine had no power at pin six, which means the cruise deactivation switch is the problem. Older Expeditions had this switch on the brake master cylinder (recall for fires, etc), but 2003 and up has it on the brake pedal itself. Once I figured out where the switch actually was, it was easy to figure out. If you have done any work around teh brake pedal and disconnected it for any reason, you gotta check this out.
Check fuse and relays fuses is on the driver side under instrument panel. relays are under the hood in the engine compartment.left inner fender well.

Dave, I am sorry I can't help you, but it sounds like you know what your doing, all I can do is offer you the troubleshoot guide, for a ford car cruise control, which should be the same. You can purchase for 20.00 on alldatadiy.com and it will give you all service info on your specific vehicle for a year. I think it is well worth the money, and generally when I need to repair any vehicle with problems it has been a life saver. I am pretty sure the electronics for this are contained in the cruise module it's self. Alldata will have a trouble shooting guide that will walk you through the repair. It could be the actual button on the steering wheel, it could be the module. You can buy these pretty cheap if you go to car-parts.com and put in what you need. Of course these are used but most yards give a warranty on them.

Check the speed sensor at the tranny or near left front tire. Use a manual or find the location on the net. This sensor usually causes problems with the cruise control.

Make sure the cable from the cruise control motor to throtle is not broken or unattached.

I had this same Problem and it was a simple vaccuum hose leak connected to the cruise control module. Try replacing this small hose.
