No lowbeams

Just bought a '94 Plymouth Grand Voyager. It is loaded and has only 89,500 actual miles. The ONLY thing that doesn't work is the lowbeam, brights work. Any idea what to do? I have changed the lowbeam fuses, the lamps, and the headlamp relay.

This schematic (fig 37) shows a "lowbeam relay". If this is the relay you changed the next step would be to check the circuit with a multimeter and find where you're loosing the voltage.http://www.autozone.com/az/cds/en_us/0900823d/80/10/cc/a4/0900823d8010cca4/repairInfoPages.htm
