I have a 98 Windstar with the same problem. According to my mechanic, it's the ABS controle module. It seems to be a common problem with these vans. Unfortunately, the module costs $1300. I am trying to find a used one, if I do and it fixes the problem, I'll let you know
Problem with the ABS.
The traction control system is turned off. If the abs light is also on, there is a malfunction.

Wheel speed sensor. have the ABS scaned
after fixing the whatever abs problems or traction control problems you had the light should go off automatically. if it does not you have not fixed the problem.

Bring to a shop that has an ABS scanner
usually it means that something is wrong with it, but you'll probably have to look in the owner's manual
