I would check the right front turn signal bulb voltage and ground. This can be done with one test that I have illustrated on the diagram. Turn the key on and turn the right side turn signals on and check it as shown. Most of the time it is either the bulb socket or the ground for the socket, especially on Taurus models! They have always had issues with grounds on the radiator support area.
