Does your 2012-2019 manual transmission Fiat 500 not start unless you jiggle the clutch pedal? The clutch safety switch (or starter interlock switch) might be bad. This is a direct replacement from Sawyer Auto. It's that little purple push-button switch mounted near the top of your clutch pedal. When you press the clutch down, it pushes the button in, completing the circuit and allowing the car to start. When it wears out, the connection gets flaky. This part is made to meet or exceed OE standards for a reliable fit and long life. Installation is usually pretty straightforward – it often involves removing a panel under the dash, unplugging the old switch, and clipping in the new one. Make sure your car is the right year and model (2012-2019 Fiat 500) before ordering. A simple fix to get your starter circuit working properly again.
