1. Disconnect Battery:
- Ensure that the negative terminal of your car's battery is disconnected to prevent any electrical accidents during the repair.
2. Remove Instrument Panel:
- To access the clock, you need to remove the instrument panel. Consult the service or workshop manual specific to your 1995 XJS Jaguar for instructions on how to remove the instrument panel.
3. Locate Capacitor:
- Once you have the instrument panel removed, locate the clock module. The clock module is typically located behind the dashboard, above the center console area.
- The capacitor that needs replacement will be a small, cylindrical component on the circuit board of the clock module. It will have a black casing with a colored stripe on its side.
4. Remove Faulty Capacitor:
- Carefully remove the faulty capacitor. You can do this by using a soldering iron to melt the solder that connects the capacitor to the circuit board. Be careful not to damage any other components on the circuit board.
5. Replace Capacitor:
- Replace the faulty capacitor with a new capacitor of the same value. The value of the capacitor should be indicated on the side of the original capacitor. Solder the new capacitor in place.
6. Reinstall Clock Module:
- Once the new capacitor is installed, carefully reinstall the clock module back into the instrument panel.
7. Reinstall Instrument Panel:
- Follow the reverse procedure from Step 2 to reinstall the instrument panel. Connect all previously disconnected electrical connectors and ensure everything is properly secured.
8. Reconnect Battery:
- Reconnect the negative terminal of your car's battery to restore power to the electrical systems.
9. Test Clock:
- Start your car and check if the clock is now functioning properly and the fading issue is resolved.
Remember, this guide provides general steps, and the exact process may vary slightly depending on the specific model of your 1995 XJS Jaguar. If you are not comfortable with electrical work or are unsure about any step, it is best to consult a professional automotive technician.
