Is there a recall regarding the cruise control? How do I remedy or trouble shoot?
It's potentially a very dangerous situation..!!!
There was a Ford recall on many cruise control systems but that was for fire hazard not turning on its self and setting. CALL Ford directly 1-800-392-3673
I would unhook the cruise control servo cable from the throttle body until this is resolved. Could be wiring, switches or a faulty servo control.
