Hello, you likley have a bad VSS or vehicle speed sensor, It controls everything not working, Located on the back of the instrument cluster, I have included a link showing the dash parts, trim plate removed, cluster removed, There just is no other detailed repair information offered
PURPOSE The vehicle speed sensor is used to monitor actual vehicle speed. Vehicle speed information is used by the ECU for fuel injection, air injection (on equipped vehicles), cruise control and electronic control of automatic transmissions.LOCATION Located on the backside of the speedometer cluster.OPERATION The sensor is a reed switch that is controlled by a rotating magnet. As the magnet passes under the sensor the contacts close momentarily, resulting in a ground signal. The frequency of these ground signals sent to the ECM is relevant to vehicle speed.The VSS inputs the ECU through terminal SPD.
