How to Replace the Knob Bulbs on a Fiat 500

Model: Fiat 500 312 - Years 2007-2024
Part: Instrument panel light

How do we change the bulbs for the manual air conditioning knobs on a Fiat 500? Let's see how to proceed. Remove the ventilation knob panel using a plastic lever (first, set all knobs to their lowest position). After disconnecting the air conditioning control panel, extract the damaged bulbs from the dashboard. Install the new bulbs and prepare to reassemble the knob panel. Be careful not to break the plastic tabs that secure the panel. Finally, test the previously installed bulbs by turning on the instrument cluster and controls.
