I have a 2002 Windstar that had the harness recall performed, yet now I am still getting the ABS/Brake lights on most of the time. The problem appears to the the ECU with a $852.00 estimated cost. There is a link to report this issue/defect to the proper authorities.
Here is the link to report the problem:
NHTSA.GOV. (National Highway Transportation Safety Administration). Use
this link. or call 1-800-327-4326.
Hope this helps. I just reported the issue this morning.
