How to Test a Fuse
A blown fuse is easy to spot and replace. Here's how:
- Turn off the vehicle and remove the key from the ignition.
- Locate the suspect fuse using the diagrams above.
- Use a fuse puller (often found in the fuse box lid) or a pair of needle-nose pliers to gently remove the fuse.
- Inspect the metal strip inside the plastic housing. If the strip is broken or melted, the fuse is blown.
- Replace the blown fuse with a new one of the exact same amperage rating. Using a higher-rated fuse can cause severe electrical damage and is a fire hazard.
Common Blown Fuses on This Vehicle
- 12V Power Outlet / Cigar Lighter (Rear Compartment F7 or F8): This is one of the most common blown fuses. It often happens when a metal object falls into the outlet or a faulty charger is used. Check the outlet for foreign objects before replacing the fuse.
- Infotainment / Radio (Passenger Compartment F10): If your radio or center screen is dead, this fuse is the first place to look. This can sometimes blow without an obvious cause.
- Trailer Lights/Brakes (Engine Compartment F34): If you frequently tow, issues with trailer wiring are a common cause for this fuse to blow. Inspect the trailer-side connector and wiring for any corrosion or damage before replacing the fuse.

Before you pull a fuse on the 2019 GMC Acadia
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
