abs power relay

can anyone tell me where the abs power circuit relay is located on a 2002 windstar? the lights come on in warm weather, error code indicates the power circuit relay tripped.

There are only (3) fuses feeding the ABS module (under driver's seat, under floorpan) all relays are on-board that module ... and I don't think very serviceable. Ford will be glad to supply you with a new "controller" ... for a few hundred smacks!

Hope its not that .... but I had to replace one on my '99.
