Overdrive button not working on the ford superduty or excursion is usually a broken wire coming from the gear selector lever. If the wire grounds out you can also end up with a blown fuse which controls some gauges, some dash lights, the overdrive button, and the TPS so the truck will not respond to the accelerator pedal. This shows how to replace the transmission gear shifter and overdrive button.
