Hi Something you won't of considered but maybe a remote possibility, this could be an effect of something completely unconnected with the cruise control. Let me explain, I once had a mondeo with a faulty door lock and the boot would not open on the button, also on the Antara when I forgot to plug in my heater plugs the stop start wouldn't work, this puzzled me for about 12 months until I recently found the problem by reading the codes and investigating.
Car designers often inhibit something inconvenient on cars when something else doesn't work, I presume the reason is you will take the car into the garage when they will check the codes and find the real reason in order that it can be repaired without you being aware. The Mondeo was a prime example the rear boot switch had nothing to do with the door lock, but when the door lock was fixed it allowed the fault code to reset then the boot would open. It took 13 trips to the dealers to sort and they ended up bringing ford in who found it straight away by just plugging in a code reader which identified the door lock in fault. This was after 3 ECU's, 2 dash buttons, 2 boot buttons and I think a boot lock had been replaced.
It is possible, and I really don't know, but their may be absolutely nothing wrong with the cruise control, but a fault code from something else may be preventing it from working. It may be worth getting the codes checked, I think someone may of mentioned this earlier. Richy
