The cigarette lighter (also known as the auxiliary power outlet or accessory socket) in a Nissan Qashqai provides a convenient power source for various electronic devices. A blown fuse is a common issue preventing its operation. This guide provides detailed information on locating, diagnosing, and replacing the Nissan Qashqai cigarette lighter fuse to restore functionality.
Benefits and Purpose of the Cigarette Lighter Fuse
The primary function of the cigarette lighter fuse is to protect the electrical circuit from overload. This prevents damage to the vehicle’s wiring and connected devices. Benefits include:
- Protection against short circuits and power surges.
- Prevention of damage to sensitive electronic devices plugged into the outlet.
- Ensuring the safety of the vehicle’s electrical system.
- Maintaining the functionality of essential accessories like phone chargers and GPS devices.
Understanding the Cigarette Lighter Wiring Diagram
A basic understanding of the wiring diagram is crucial for troubleshooting. Here’s a simplified view:
- Power Source: The circuit originates from the vehicle’s battery.
- Fuse Box: The cigarette lighter fuse is located within one of the vehicle’s fuse boxes, usually the one under the dashboard or in the engine bay.
- Wiring: Wiring runs from the fuse box to the cigarette lighter socket.
- Ground: The circuit is completed via a grounding point connected to the vehicle’s chassis.
A typical wiring issue involves a short to ground, which causes the fuse to blow immediately upon replacement. Inspecting the wiring harness near the socket for damage is crucial.
Practical Application
Follow these steps to locate and replace the Nissan Qashqai cigarette lighter fuse:
- Locate the Fuse Boxes: Consult your Nissan Qashqai owner’s manual to identify the fuse box locations. Typically, there’s one under the dashboard and another in the engine bay.
- Identify the Correct Fuse: Refer to the fuse box diagram in your owner’s manual to pinpoint the fuse specifically designated for the cigarette lighter (auxiliary power outlet). The diagram often uses symbols to indicate the function of each fuse.
- Inspect the Fuse: Use a fuse puller (often included in the fuse box) to remove the fuse. Examine it closely. If the wire inside is broken or the fuse appears burnt, it’s blown and needs replacement.
- Replace the Fuse: Use a new fuse with the exact same amperage rating as the original. Using a fuse with a higher amperage can damage the electrical system.
- Test the Outlet: After replacing the fuse, test the cigarette lighter socket with a known working device, such as a phone charger.
1. Troubleshooting
- Fuse Blows Immediately After Replacement: Indicates a short circuit in the wiring. Inspect the wiring near the socket for damage or exposed wires. Professional diagnosis might be required.
- No Power Even with a Good Fuse: Check the socket itself for damage or debris. The socket might need to be replaced.
- Intermittent Power: Loose wiring connections can cause intermittent power. Inspect and tighten all connections.
2. Tips for Fuse Management
- Always keep spare fuses of the correct amperage in your vehicle.
- Never use a fuse with a higher amperage rating than the original.
- Consult a qualified mechanic if you are unsure about any aspect of fuse replacement or electrical troubleshooting.
Frequently Asked Questions (FAQs)
Q: Where is the cigarette lighter fuse located in a Nissan Qashqai?
A: The fuse is typically located in either the fuse box under the dashboard or in the engine bay. Consult your owner’s manual for the exact location and diagram.
Q: What amperage fuse does the cigarette lighter use in a Nissan Qashqai?
A: The amperage varies depending on the model year, but it’s usually 15A or 20A. Refer to your owner’s manual or the fuse box diagram for the correct rating.
Q: Can I use a higher amperage fuse if the original keeps blowing?
A: No. Using a higher amperage fuse can damage the electrical system and create a fire hazard. Identify and fix the underlying cause of the blown fuse.
Conclusion
Understanding the function and location of the Nissan Qashqai cigarette lighter fuse is crucial for maintaining the functionality of your vehicle’s auxiliary power outlet. By following the steps outlined in this guide, owners can effectively troubleshoot and resolve common fuse-related issues, ensuring the safe and reliable operation of their electronic devices while on the road. Remember to always prioritize safety and consult a professional if you are uncomfortable with any electrical repairs.
