* Inside the Vehicle: This is usually located under the dashboard, on the driver's side. You might need to remove a small access panel to reach it. The exact location can vary slightly depending on trim level and options.
To be absolutely certain, check your owner's manual. It will have diagrams showing the locations and functions of all fuses and relays. If you don't have the manual, you can often find a digital version online through the GMC website or a reputable automotive repair manual provider.
