Mine is now doing same thing. well, the airbag (4 blinks) did since i bought the car...
for the cruise, there are holes in the brake/clutch pedals that need to be covered to activate the switch...i duct taped a penny there and it worked fine for a while. then stopped again and also horn stopped. found bad horn relay, so replaced that with new.. then cruise worked again...
now cruise stopped again and the horn still works, but not sure why.... man i miss cruise.
