2022 GMC Acadia Fuse Box Diagram & Amperage

Quick Answer

The 2022 GMC Acadia has three main fuse box locations: under the hood, under the instrument panel (passenger side kick panel), and in the cargo area on the driver's side.

Under-Hood Fuse Box

This fuse box is located in the engine compartment on the driver's side, near the battery. It contains fuses and relays for critical engine functions, ABS, and some exterior lighting.

Relay Locations (Under-Hood):

• RL1: Fuel Pump Relay
• RL2: Starter Relay
• RL3: Low Beam Headlight Relay (Left)
• RL4: Low Beam Headlight Relay (Right)
• RL5: High Beam Headlight Relay (Left)
• RL6: High Beam Headlight Relay (Right)
• RL7: ABS Pump Relay
• RL8: Blower Motor Relay
• RL9: A/C Clutch Relay

Instrument Panel Fuse Box (Passenger Side Kick Panel)

This fuse box is located behind the passenger side kick panel. To access it, you will need to remove the kick panel trim. It primarily protects interior electrical components and accessories.

Rear Cargo Area Fuse Box (Driver's Side)

This fuse box is located in the rear cargo area, behind a trim panel on the driver's side. It typically houses fuses for rear accessories and features.

How to Test a Fuse

Diagnosing a blown fuse is a straightforward process. You will need a fuse puller (usually found in one of the fuse boxes) and a fuse tester or a multimeter. Always turn off the ignition and any affected circuits before testing.

1. Locate the suspected fuse: Refer to the fuse diagrams above and the legend on the fuse box cover to identify the fuse for the malfunctioning component.
2. Visually inspect: Many fuses have a clear plastic body. Look for a broken wire inside. If it's broken, the fuse is blown and needs replacement.
3. Use a fuse tester: A simple fuse tester lights up if the fuse is good. Touch the probes to the two small metal contacts on top of the fuse. If it lights up, the fuse is good. If not, it's blown.
4. Use a multimeter (for accuracy): Set your multimeter to the continuity setting (often indicated by a speaker icon). Touch the probes to the metal contacts on the top of the fuse. A good fuse will show continuity (the multimeter will beep or display '0' ohms). A blown fuse will show no continuity or 'OL' (open circuit).
5. Replace with the correct fuse: Always replace a blown fuse with a new one of the exact same amperage rating, color, and physical size. Using a fuse with a higher amperage can cause severe electrical damage or even a fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more common than others due to usage or circuit demands. If you experience an issue, here are some common fuses to check first on your 2022 GMC Acadia:

• Cigar Lighter/12V Power Outlets (Instrument Panel Fuse Box, F4 & F5): These fuses are often overloaded by charging multiple devices or using high-power accessories. If your phone charger or portable air pump stops working, check these first.
• Blower Motor (Under-Hood Fuse Box, F11): The blower motor fuse can blow if the motor is failing, if there's an obstruction in the blower fan, or if there's a sustained period of high fan speed usage.
• Radio/Infotainment System (Instrument Panel Fuse Box, F1): Issues with aftermarket accessories, wiring shorts, or even a brief power surge can sometimes lead to this fuse blowing, resulting in a dead radio screen.
• Headlights (Under-Hood Fuse Box, F5, F6, F7, F8): While less common with modern LED systems, a short in the wiring or an issue with the headlight assembly can cause these fuses to blow. If one or both headlights are out, check the relevant fuse.
• Tail/Park Lights (Rear Cargo Area Fuse Box, F1 & F2): Issues with trailer wiring or external light modifications can sometimes cause these fuses to blow, leading to non-functional tail or park lights.

Remember to always refer to the specific fuse legend printed on the inside of your fuse box cover for the most accurate information, as fuse configurations can sometimes vary slightly with different trim levels or optional equipment.
