2015 Chevrolet Silverado 1500 Passenger-Side Interior Fuses

Locating the right-side block

Open the passenger door and remove the access cover at the passenger-side end of the dash. The searchable chart below covers radio, USB, blower, seat, lighting, body-control, window and retained-accessory circuits. Optional equipment may leave some positions unused.

Finding an electrical problem

Confirm the exact protected circuit and whether it should be powered with ignition on, ignition off or an accessory command active. If a replacement fuse fails immediately, stop; the fault is likely downstream rather than in the fuse itself.

• Match all cavity labels to the factory legend.
• Switch the relevant load off before pulling a fuse.
• Check the equipment list before assuming a position should be populated.

Tracing repeated blown fuses

Disconnect the affected accessory only if the correct procedure permits it, then isolate the circuit in stages. Chafed harnesses near movable seats or trim can cause intermittent shorts. If the fuse opens under load, stop replacing it repeatedly; the underlying fault requires repair.

Radio, USB, blower and right-side controls

The right-dash owner chart lists radio at 18, USB/obstacle detection at 27, front HVAC blower at 43, right door window motor at 42, and passenger seat at 47. Verify whether the circuit shares a module or accessory feed. A blown fuse may be a symptom of a short rather than the root cause.

When the fuse is good but the accessory stays dead

Check the correct ignition state, connectors, switch or module commands and ground path. For an inoperative blower, test the circuit and control module rather than replacing the motor solely from the symptom. If multiple unrelated features are dead, a shared feed, low battery or body module problem may be responsible.
