Locate the cabin power panel beneath the dashboard on the driver side and compare each slot with the printed label before removing any element. This prevents disconnecting active circuits such as lighting or control modules.
The pickup from this model year uses a structured layout where low-current inserts (5A–15A) support dashboard electronics, infotainment, and memory functions, while mid-range ratings (20A–30A) handle power seats, windows, and accessory outlets. Each position is tied to a specific system, making accurate identification necessary before replacement.
Check the amperage value printed on top of each component and match it exactly. For example, instrument cluster circuits typically use 10A, while power outlets and auxiliary ports often require 20A. Installing a higher-rated piece can lead to overheated wiring behind the panel.
The layout printed on the cover or in the manual maps slot numbers to circuit names such as BCM, radio, trailer brake controller, and HVAC controls. Use this reference to trace which system lost power and narrow down the faulty component quickly.

Open the driver-side lower dash panel and read the printed chart on the cover to match each slot number with its circuit before pulling any element. The layout groups low-current lines (5A–15A) for radio, cluster, and memory near the top rows, while mid-range ratings (20A–30A) for power seats, windows, and accessory outlets are positioned lower. Body control module, HVAC controls, and trailer brake circuits are assigned to dedicated positions, each labeled to reduce guesswork during troubleshooting.
Use the slot numbering and labels together to trace faults quickly:
- Top row: lighting, dash electronics, and retained power circuits
- Center rows: switches, control modules, and infotainment
- Lower section: higher load cabin accessories
Check amperage printed on each piece and replace only with the same rating; repeated failure in one position points to wiring damage or a faulty connected component.
Interior fuse box location under dashboard and access steps
Reach under the driver-side dashboard near the kick panel and locate the rectangular cover secured by clips. Pull the panel outward by hand or use a flat plastic trim tool to release it without damaging the edges.
The cabin power distribution unit sits slightly above the footwell, mounted behind the lower trim. Use a flashlight to see the slot labels clearly, as the area is recessed and partially hidden by wiring and brackets. The cover usually includes a printed chart showing slot numbers and circuit names for quick reference.
Turn off the ignition and remove the key before accessing the panel, then pull components straight out using a small extractor tool stored in the engine bay unit. Keep track of positions to avoid reinstalling parts into the wrong slots.
