Locate the flat panel on top of the dashboard directly in front of the passenger seat.
Locate the durable, black plastic weather-sealed box mounted to the frame rail. Accessing the Fuses
module uses Field Effect Transistor (FET) technology to detect shorts and temporarily cut power. Primary Control: Single SAM (SSAM) Finding the trailer light fuse on a 2019
Open the passenger door, face the dashboard, and lift or remove the plastic cover panel on top of the dash.
Clean off any road grime or debris from the box cover to prevent dirt from falling inside. Unlatch the heavy-duty clips securing the cover. Lift the cover off to expose the fuse grid and relays.
Lift the panel away to expose the main interior fuse and relay matrix. Comprehensive 2019 Cascadia Trailer Fuse Diagrams Share public link : Look for water intrusion
Because the 2019 model uses electronic controls (FETs) for circuit protection, standard fuse-swapping may not be the solution. JustAnswer Self-Resetting Circuits:
Shut down the truck and remove the key from the ignition.
Use a fuse puller to extract the suspected fuse (e.g., F2 for tail lights). Look at the metal strip inside the clear plastic. If the loop is broken or burnt dark, the fuse is blown.
