The ignition switch is the key-operated switch that sends battery power to the ignition, starting and accessory circuits depending on key position. As a switch wears, its contacts may stop passing current reliably.
Signs this part may need replacing: the engine does not crank when the key is turned to start, the gauges or accessories get no power in the run or accessory positions, or the engine cuts out while driving. Other faults can cause the same symptoms, so diagnose the cause before replacing the switch. If a failed ignition switch is the cause, US-54 replaces it.
Disconnect the battery before you work on ignition wiring. Follow the vehicle's service information for the removal and installation steps.
