- Sunroof Fuse: Protects the sunroof motor circuit.
- Cruise Control Fuse: Powers the cruise control system.
- Interior Lights Fuse: Controls the interior lighting.
- Radio/Amplifier Fuse: Protects the radio and amplifier circuits.
Underhood Fuse Box
The underhood fuse box primarily contains fuses and relays for engine-related components, such as the fuel pump, ignition system, and cooling fans. This fuse box is usually located near the battery or on the fender well. Again, consult the diagram for the precise location and function of each component.
Commonly Found Fuses in the Underhood Fuse Box:
- Fuel Pump Fuse & Relay: Protects the fuel pump motor and its control circuit.
- Air Conditioning Compressor Fuse & Relay: Protects the A/C compressor and its control circuit.
- ECM/PCM Fuse: Powers the Engine Control Module (ECM) or Powertrain Control Module (PCM), critical for engine operation.
- Ignition Fuse: Provides power to the ignition system.

OBD2 Port Location in a 2006 Pontiac GXP 5.3
The OBD2 port (On-Board Diagnostics) in a 2006 Pontiac GXP is typically located under the dashboard, on the driver’s side, near the steering column. It’s a standardized 16-pin connector. This port allows you to connect a diagnostic scanner to retrieve trouble codes, monitor engine performance data, and troubleshoot various vehicle systems.
Importance of Fuse Box Diagrams
Having access to the correct fuse box diagrams is essential for troubleshooting electrical issues. Always refer to the diagrams specific to your vehicle’s year and model, as fuse locations and functions can vary. Using the wrong diagram may lead to incorrect diagnosis and potential damage to your vehicle’s electrical system.
By understanding your 2006 Pontiac GXP 5.3’s fuse box layout and utilizing the OBD2 port, you can effectively diagnose and address many common automotive problems. Always consult your owner’s manual for the most accurate and detailed information regarding your vehicle’s electrical system.
