Re: 2003 Windstar brake light and abs light stay...
I have had this scenario many times. It is usually one of two things...
1) Brakes are worn and need to be replaced (front pads/rotors)
2) One ore more of the ABS sensors are not reading correctly. This could be either a hub & bearing that need replacing, or just a sensor. It would need to be scanned and road tested to pinpoint the problem.

First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0290 or C0292
Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit
Red lite comes on at startup to ck. system. If amber lite stays on, ck. brake fluid level and see if emergency brake is partly up. This shows problem with anti lock system if it stays on, not main brake system. If all is ok with this but still stays on Have ABS system checked. Haynes repair manual, 95-2003 Windstar, all models.
try checking your brake fluid level it may be low or your mater cylinder may need replacing, also may need to replace brakes, you can get manual for your windstar they are about 20 bucks ant most auto stores
there is a Safety Recall Notice 01S08Grease used on the adjustable pedal assembly may
enter the brake lamp switch and contaminate the contacts. This may
cause one or more of the following symptoms to occur:
-Brake lights stay illuminated or are inoperative.
-Shift Interlock disabled (will be able to shift out of "Park" position without depressing the brakes.
-Speed Control will not activate.
-Cannot shift the vehicle out of "Park."
-ABS Warning light illuminates on vehicles with ABS
I think it means the Antilock Brake System is disengaged. So, a code has been stored in the abs computer. Standard obd tester cannot check these codes, must visit your dealer or some autoshop with ABS reader.
According with the service manual: During starting the RED brake light should briefly come on and then go
off. If the RED light stays on, it indicates a problem in the main
braking system, such as a low fluid level, or the parking brake is still
You may need to make sure that Ford Factory pads have built in sensors on them. In many vehicles these built in sensors will cause the abs and brake lights illuminate when the brake pads wear down to a certain point. Also make sure to check your brake fluid regularly. I used to work for a Infiniti dealer in the service dept. When the brake fluid was low it caused the brake lights to come on as well. Just a few things you can check out yourself before taking it in to the dealer to check for codes.
It sounds like you have a bad sensor on one of the wheels.Sometimes you can take the veh to autozone or advanced auto parts and they can hook it up to thier scanner and tell you which one is bad(they do this for free) if they have an abs scanner.
