I also have an ABS light problem with my 2000 Windstar. It has come on & off intermittently for the past couple of years. I haven't worried about it since my mechanic told me my brakes would still work (just not the ABS). The one strange thing is that the light stays off during the cold winter months. But once it starts warming up in the spring the ABS light problem appears again. Any one have an idea what could cause this strange behaviour.
