Do a gOOgle search for test procedure. Your chassis, as 1994 or 1995 is NOT OBD-2 so you don't have a test port under your dashboard. The Cruise is tested separately from the underhood OBD-1 connector near the master cylinder. Once you find the Cruise test process AND the connecting point, it should blink out a code suggesting what's wrong. That said, here's what I've seen and heard about cruise failure on these:
Rear ABS (RABS) brake sensor called Vehicle Speed Sensor (VSS) mounted on the top of the differential. But if it's out, there's usually a Check Engine indicator and the transmission may not go into Overdrive.
IF you don't have a Driver Side Airbag (doesn't say "SRS" on the horn pad) THEN
Clean the Cruise switch contacts in the steering wheel spokes. I haven't done that but a neighbor did, and was successful fixing his.
Possibly the "Clock Spring" in the steering wheel hub has a bad connection to something for the cruise.
Again, DON'T mess with the Wheel if you have SRS!!!
If your Brake Lights work properly and no fuses are blown, I don't think the Ford recall (switch on master cylinder) will help. You can visit a Ford dealership with your VIN and they can tell you what applies and if it was ever done.
