2014-2020 GM Truck & SUV Power Inverter Guide: Silverado, Tahoe, Acadia & More
Diagnosing and replacing the 110V AC power inverter module that fails, leaving your outlets dead.
- The most common cause of a dead 110V outlet is a blown fuse, not a failed inverter. Always check fuses first.
- Location and replacement difficulty vary greatly. It's an easy under-dash job on trucks/SUVs but a difficult under-console job on crossovers (Acadia, Enclave, Traverse).
- This part is only for vehicles with the 110V outlet option (RPO code KI4 or KI6). Verify your vehicle has this option before buying.
- New aftermarket replacements are not common, making a warrantied used OEM part a very good value.
Symptoms of a Failing Power Inverter
When the power inverter module begins to fail, the symptoms are usually straightforward and directly related to the 110V outlet's performance.
- Outlet is Completely Dead: The most common symptom is a complete lack of power at the 110V outlet. The indicator light will not illuminate, and any device plugged in will not receive power.
- Power Cuts In and Out: The outlet may provide power intermittently. It might work for a few moments and then suddenly shut off. This can sometimes be caused by the unit overheating or an internal component failing under load.
- Blinking Indicator Light: On many models, if you plug in a device that draws too much power (over 150 watts), the indicator light on the outlet will blink and then shut off. However, if this happens even with low-power devices (like a phone charger), it can be a sign that the inverter module itself is faulty.
- Audible Clicking or Buzzing: You might hear a clicking or buzzing sound from the inverter module's location (under the dash or console) when you attempt to use the outlet, followed by it shutting down.
Pro Tip: Before assuming the inverter has failed, always check the fuse first! A blown fuse is a very common cause for a dead outlet and is a much simpler and cheaper fix. Fuse locations vary by vehicle (see Vehicle-Specific Information below).
Vehicle-Specific Information and Part Locations
This power inverter is used across two distinct GM platforms, and its location and the difficulty of replacement are very different between them.
Platform 1: Full-Size Trucks & SUVs
Vehicles: 2014-2019 Chevrolet Silverado 1500, 2015-2019 Silverado 2500 HD, 2014-2019 GMC Sierra 1500, 2015-2019 Sierra 2500 HD, 2015-2020 Chevrolet Tahoe, 2015-2020 GMC Yukon, 2016-2020 Cadillac Escalade
- Part Location: The power inverter module is located under the driver's side dashboard, to the left of the steering column. It is mounted to a metal bracket up behind the lower dash panel.
- Replacement Difficulty: 1 out of 5. This is a very straightforward repair. Access is gained by removing the lower knee bolster panel below the steering wheel, which is typically held on by a few T15 Torx screws. The inverter itself is secured by a single 10mm nut.
- Fuse Location: The fuse for the AC inverter is typically fuse F35 (a 25A fuse) located in the instrument panel fuse block on the passenger side of the dashboard.
Platform 2: Crossovers
Vehicles: 2015 Buick Enclave, 2015 GMC Acadia, 2015 Chevrolet Traverse
- Part Location: On these crossover models, the 110V outlet is located on the rear of the center console. This means the inverter module is located underneath the center console assembly between the front seats.
- Replacement Difficulty: 3 out of 5. This is a more involved job than on the trucks. It requires the complete removal of the center console to access the module. This involves removing various trim pieces, screws, and electrical connectors.
- Fuse Location: The fuses for the power outlets are located in the under-hood fuse block. There are several fuses related to power outlets, often labeled "AUX POWER" or "PWR OUTLET".
Warning: These vehicles require the correct Regular Production Option (RPO) code for this part to be present. Check the silver sticker in your glove box. The trucks and full-size SUVs typically use option code KI4. The crossovers with the console-mounted outlet may use option code KI6. Always verify your vehicle's options before purchasing a part.
Buying a Used Power Converter
Since new aftermarket direct-fit replacements are not widely available, a used OEM module is an excellent, cost-effective option. Here’s what to look for:
- Verify the Part Number: The most current part number is 84181077. This number supersedes many older part numbers like 22817310, 23217954, 23287325, and 23472991. A used part with any of these numbers should work for the truck and full-size SUV platform, but matching your original part number is always the safest bet.
- Inspect the Connector Pins: Carefully examine the electrical connector and the pins inside the module. Look for any signs of green or white crusty corrosion, or pins that look burnt or melted. Do not buy a unit with any visible connector damage.
- Check for Physical Damage: The plastic housing and metal cooling fins should be intact. Avoid any units with cracked cases or heavily damaged fins, as this could indicate it was dropped or damaged during removal.
- Source from a Reputable Seller: Purchase from a recycled parts seller that offers a warranty. This gives you protection in case the used module is also faulty.
Cost of Replacing a Power Converter
The cost can vary significantly depending on the vehicle platform and whether you do the work yourself.
| Part/Service | Estimated Cost |
|---|---|
| New OEM Module | $140 - $170 |
| New Aftermarket Module | Not readily available |
| Used OEM Module | $40 - $90 |
| Shop Labor (Trucks/SUVs) | $75 - $150 (0.5-1.0 hours) |
| Shop Labor (Crossovers) | $180 - $300 (1.5-2.5 hours) |
Frequently Asked Questions (FAQ)
My 110V outlet isn't working. Is the inverter definitely bad?
Not necessarily. Before replacing the inverter, always perform these two checks: 1) Check the fuse. A blown fuse is the most common problem. 2) Make sure the device you're plugging in doesn't draw more than 150 watts. The inverter has a protection circuit that will shut it down if overloaded. If the fuse is good and the outlet still doesn't work even with a low-power device like a phone charger, then the inverter module is the likely culprit.
Do I need to program a replacement power inverter?
No. This power inverter module is a plug-and-play component. It does not require any special programming or calibration after installation.
Can I upgrade to a more powerful inverter?
No, you cannot simply swap the factory 150-watt module for a more powerful aftermarket unit. The factory wiring, fuse, and vehicle electrical system are all designed for the low power draw of the original part. Installing a higher-wattage inverter would require running new, much thicker gauge wires directly from the battery, adding a new high-amperage fuse, and would be a completely custom installation.
Where is the fuse for the 110V power outlet?
It depends on your vehicle. For the full-size trucks and SUVs (Silverado, Sierra, Tahoe, Yukon), it is usually a 25-amp fuse in the passenger-side interior fuse panel, often in slot F35. For the crossovers (Acadia, Enclave, Traverse), the relevant fuses are typically in the fuse box located in the engine compartment. Always consult your owner's manual for the exact location and rating.
