Hello, it's a matter of learning why the speedometer is not responding. Is it an instrument cluster module concern? A wiring concern? Signal from the speed sensor? The driven gear that drives the sensor? Hands on testing is required to find out what's going on. A Ford compatible diagnostic tool capable of reading chassis as powertrain module components is needed.
