Aux Power Outlet Not Working

Hi all, could use your help!

 

2008 Chevy Silverado Crew Cab Short Bed 4x4.

There are two auxillary power outlets in the front dash.

Over the weekend, I plugged in my 200W inverter into the left outlet to allow my sister to charge her cell phone with her standard 120V charger.

The inverter worked for 3 minutes and then quit. I figured the inverter went bad, so I moved it to the right-most outlet to check, and it still didn't work.

 

After a little checking, I found that I had blown the 20A fuse in the mini-fuse panel by the driver's door (fuse #16). I replaced the fuse but now only one of the two outlets works. The right-most outlet works, but the one on the left still does not work with the new fuse.

 

Any idea why the one on the left doesn't work? Is there another fuse I'm missing? Did I fry the outlet? I can't believe the 200W inverter would draw more power than the 12V aux power outlet is capable of...

 

Thanks!

In the fuse panel inside the truck, there was AuxPwr and AuxPwr2. Both were 20Amps. I replaced AuxPwr because it was blown. AuxPwr2 was not blown.

I looked at the fuses under the hood too...didn't pull any out because none of the descriptions jumped out at me as being something related to the aux power outlets. Any idea which one I'd look for?

My 2004 Suburban may be different than your truck. Under the hood I have a fuse described as "AUX PWR" described as Auxilary Power Outlet-Console. The Instrument Panel fuse block has a fuse described as "AUX PWR 2" described as Rear Cargo Area Power Outlet.

 

I hope that helps.

+1. And they're two different amperages.

One might be labeled as a cigarette lighter. If I remember right the two in the dash are on separate fuses and only one is labeled as "aux pwr"

That was how the trucks I have worked on in the past were hooked up.....one outlet was via the aux pwr and the other outlet and cig lighter are wired via the cig lighter fuse. Depending on your truck that fuse is usually in the truck in the instrument panel fuse block. Check your manual to make sure.

The two last posters were correct.

 

Tonight after work, I did a more thorough look at the two fuse panels.

 

The 12V outlet on the right side of the dash was the 20A "Aux Pwr" fuse in the instrument panel fuse block.

The 12V outlet on the left side of the dash was the 20A "LTR" fuse in the engine compartment fuse panel.

 

Thanks for the replies. Now...I'm off to replace the power inverter that is so aptly blowing these fuses...

      2 speed transfer case optional now?

      By Chuck FB · Posted

      I can only guess as well that something was clicked on that brought you to the half ton choices by accident. By all means try again and chose the 3500 and sort out that its the cab and box configuration you want and choose four wheel drive ( rather obvious to have a transfer case ) and to make sure the dually isn't chosen. I find or at least did a couple of years ago when I was sifting through the options that it would sometimes jump ahead after choosing the series of truck and in this case 3500 and skip some of the other initial configuration choices and have to watch the heading bar and sometimes back up by choosing the first in the series of option break downs. I think sometimes the computer will remember items that were last chosen and skip over the first part. Anyway go through it all and depending on the trim level chosen and I think the LT is one that may fall into that where the option of having the 4 high auto transfer case can be chosen, where as a High Country doesn't show that option as it just comes with the fancier ( not necessarily better though in terms of potential problems ) transfer case but for sure both transfer case choices are equipped with high and low range in the HD truck segment. Like Newdude said who works at a dealership, its the half tons that are the ones that will come with the single speed unless certain options or trim levels are chosen that add the two speed transfer case but as your looking at an HD, you don't have to worry about that hot mess.    One item that at least didn't show up and not sure if it does yet or not in the HD options on the manufactures pubic website is the upfitter in cab switch option if one is desiring that. Unfortunately its not wired in at the factory but the panel with the switches is on the dash but the wiring harness to be installed gets tossed under the rear seat to be installed by whomever after the fact to complete the installation.

      Yesterday we brought home a 6yr  old Havanese dog from a nearby SPCA.  We've had her for 24 hours and we are delighted with how well she is adjusting to her new home.  It  was a huge decision to adopt a dog at this stage in our lives but we believe we made the right choice!   it was reported that her first 6 years were ones of neglect.  I think she's already realizing her life is going to get a whole lot better...  so is ours!

      Which 2027 engine will you choose?

      No doubt, I definitely agree with you. However, considering the 6.2 and 3.0 have been catastrophically failing with very little miles, I figured I would put trouble free. I’m at 18,4xx and still not a single issue.

      It’s never dry here but it gets hot. My 4 vehicles I keep at home drive an 18 mile loop. One 6 days a week. Two about 3 days each and one once a month. Only one goes on trips about 4 times a year 1000 to 2000 miles each time. One 26 years old gets driven once a month for 22 years. One 14 years old goes 6 days a week. The other two are recent at 2 and 4 years. All are performing normal no extra service other than that would be half of recommended or severe service in the maintenance manual. No extra water or steam out the exhaust or premature plug wear. I would consider an 18 mile loop would be enough. So apparently once a month at 18 miles for 22 years has kept the collector car running well. About 45 minutes a month.
