Has anyone replaced the power inverter?

fatkid24 · February 6, 2018

I have a 2016 LT CC and I noticed that my 110 plus LED isn’t on. I checked the 50A fuse in the left of the dash which I believe should be where this gets its juice. The other USB and cigarette lighter power ports are functioning when the truck is running and when it is not. I first assumed it was a fuse. The others working leads me to the power inverted. I’ve read that it has issues and can go bad. Has anyone replaced it themselves? Any help would be great! Thanks fellas!

Man, you're way out in left field on this. There is nothing in the left ip fuse box that has anything to do with the inverter. Pick a big fuse somewhere and that's good so it must be the inverter? Some inverters fail but have only seen a very few. 2 fuses in the right ip fuse box ( 1 via the bcm ) run the inverter. A 25a and a 10a. 9 times out of 10 , someone plugged a device that requires way too much wattage. I'ts only good for 150 watts.

I replaced the 25A blown fuse and plugged in my laptop and blew the fuse immediately. I meant the right fuse box. My mistake.

The 50A fuse in the left side that controls the other power and USB is fine. Everything else is good. Just the 110. I would like to use it for my laptop. It’s adaptor is 45W.

I have seen them do exactly that. I have even plugged in a three pronged household outlet tester and blown the fuse. Problem is, I can't remember if an inverter or outlet fixed it. I'm fairly sure an inverter fixed it though.

I’m headed in to the dealer Friday. I’ll update then. Thanks for checking back.

Dealer says it’s the plug, not the inverter. Ordered the plug. I’ll update once it’s in and functioning.

Went back to the dealer yesterday, they swapped the plug and it immediately blew the fuse. They checked it in and it was the inverter that had to be replaced. They said the plugs cause shorts most of the time but, for some reason, it was the inverter.

Do you think the inverter is covered by extended warranty?

fatkid24 · September 17, 2020

I think that depends on the warranty. I would definitely make them tell me no. It seems like that inverter was going to be a couple hundred bucks. Make them say they won’t do it. The question is free!

well if anyone wants to do it yourself its fairly simple. I have a 2015 silverado 1500 and my inverter went bad. its under the steering wheel behind the cover, or right above the brake pedal/gas pedal. There is 1 nut on the back side of the plate (not the two on the front of the plate) and an orange cable of wires connects to it. I was able to order on ebay for $27. The inverters for a 2015 are compatible for the 2015-2019 silverado (per my ebay purchase)

Any chance you have a link and are these upgraded to handle higher power items or just OEM replacements?
