Calibrate Windstar 2000 headlights

I am new on this page .. a thousand congratulations .. I just bought a 2000 windstar .. and the headlights bring them out of place .. the high are low. And the casualties kissing the tires ... I know how to calibrate the headlights of other vehicles .. but of the windstar .. I do not find him anywhere how to regulate them in height and horizontality ... anyone knows where the screws, cocks or brooches are to regulate them ??? .. urgent why I cannot handle at night.
