To locate the main power unit under the hood, open the vehicle’s front panel and look for a rectangular compartment near the engine. This area is where you’ll find the critical components for larger systems, including the engine control, lights, and HVAC system. If any of these functions fail, this is the first place to inspect. The layout is typically well-marked for ease of identification.
Next, check the secondary panel beneath the dashboard on the driver’s side. This unit controls power for smaller in-cabin systems like the audio system, power windows, and interior lighting. The fuse slots here are labeled clearly, making it easier to identify and address problems with the vehicle’s interior functions.
For an effective diagnosis, consult the vehicle manual or inspect the panel cover for the circuit labels. This information will help you identify which component corresponds to each slot. Replace any malfunctioning components with the correct parts to restore functionality and ensure your vehicle’s electrical systems run smoothly.

Start by locating the primary power panel under the hood. It houses the critical circuits for engine management, lighting, and cooling systems. This panel is easy to reach and typically has its layout clearly marked. If any of the major systems stop working, check this area first for damaged or blown circuits.
The secondary panel inside the vehicle is found beneath the dashboard on the driver’s side. It controls power for the cabin components, including the audio system, interior lighting, and power windows. Inspect this panel if you experience issues with the vehicle’s in-cabin functions, such as malfunctioning electronics or accessories.
Before replacing any parts, check the owner’s manual for circuit assignments or refer to the markings on the inside of the panel cover. Use only components with the correct amperage to avoid damaging the electrical system. If the issue persists despite replacing a faulty part, a deeper inspection of the wiring and relays may be necessary.
Locating the Main and Auxiliary Power Panels in Chrysler Town and Country
To locate the primary power panel, open the hood and look near the engine for a rectangular unit. This section controls the major electrical systems, including the engine, lights, and air conditioning. It’s easily accessible and typically has a diagram on the cover for quick identification of each circuit.
Main Power Distribution Unit

This panel is located in the engine compartment, usually near the battery. It contains high-power circuits that supply energy to the most important systems of the vehicle. If any large components, such as the starter or headlights, stop working, the problem is likely in this area. Check for burnt-out or blown components and replace them as necessary.
Secondary Electrical Panel

The secondary panel is located inside the vehicle, usually under the dashboard on the driver’s side. It manages smaller electronics, such as the radio, windows, and interior lighting. To access it, remove the panel beneath the steering wheel. If any cabin electronics are malfunctioning, inspect this panel for faulty parts or blown circuits.
