Owner's Manual is your friend...page 9-29, 9-30

Retained Accessory

Power (RAP)

The following vehicle accessories

can be used for up to 10 minutes

after the engine is turned off:

. Audio System

. Power Windows

. OnStar System (if equipped)

. Sunroof (if equipped)

These features work when the key

is in ON/RUN or ACC/

ACCESSORY. Once the key is

turned from ON/RUN to LOCK/OFF,

the windows and sunroof continue

to work up to 10 minutes or until any

door is opened. The radio continues

to work for up to 10 minutes or until

the driver door is opened.

Accessory Power Outlets (APOs)

The vehicle may have APOs in

several locations. See Power

Outlets on page 5-6.

The APOs in the console or center

seat position are powered by RAP.

They will continue to work for up to

10 minutes after the key is turned

from ON/RUN to LOCK/OFF, or until

the driver door is opened.

The APOs on the center stack come

from the factory powered directly

from the vehicle battery, and supply

accessory power at all times,

regardless of ignition key position.

If electronic items are left plugged

into these APOs for long periods of

time with the vehicle off, the vehicle

battery could be drained. The

vehicle may not start if the battery is

allowed to drain for an extended

period of time.

The source of power for the APOs

on the center stack can be changed

from direct battery power to RAP by

moving the fuse at location 10, in

the left instrument panel fuse block,

to position 11. Once the fuse is

moved, the APOs will continues to

work for up to 10 minutes or until

the driver door is opened. See

Instrument Panel Fuse Block (Left)

on page 10-49 or Instrument Panel

Fuse Block (Right) on page 10-52.

If you are not comfortable

performing this change, see

your dealer.

I don't swing that way, but I could just kiss you right now! I can't tell you how many times I had to jump start my truck because I forgot to unplug my dash cam. Overnight was usually okay, but more than that meant a dead battery. After it happened again yesterday, I was determined to find a way to make the power outlet go cold when the key was off. I actually came in the house to use Google to try to find a switched wire I could tap off of and run to a relay for the power outlet. I had Googled for solutions before but never came across this post. Like some of the others, my manual says nothing about switching the fuse to the other pins, but it worked perfectly. THANK YOU!!!

I have a 2015 Silverado WT.  The fuse panel and the fuse diagram is really a little confusing to me.  Where the diagram appears to show two fuse slots, 10 and 11, the actual panel appears to have a single slot with three pins.  There is a 50 amp fuse located to the right as it came from dealer.  So if one assumes that 10 is on the left and 11 on the right according to diagram that seems fuse was in the 11 slot.  However, I am not timid, so I tried moving the 50 amp fuse from the center and right pins to the left and center pins and that did the trick.  Not sure exactly how but it did.  Also, my owners manual does not match the excerpt given on this site.

My 2018 owners manual says

"The power outlets on the center

stack and in front of the cupholders
are powered at all times. The power
outlets inside the storage area and
on the rear of the console are
powered when the ignition is on or
in ACC/ACCESSORY, or when
Retained Accessory Power (RAP) is
active."

My 2015 says same thing.  But moving one of the large fuses to the left changed the one on center stack to RAP.

Just an update, even though the manual says what it does, moving the fuse works on my 2018

Broke the top off the fuse when I moved it, problem is I can't find a replacement.  The Dealer only shows a 40 amp but it's a 50 amp.  I've searched the several different parts stores online and can't find one.  Any suggestions??

 

 

Thanks

 

Had to make a couple of stops, but found a 50amp replacement at advance

Good.  I was going to suggest try the 40.  Worst that can happen is it blows.  I seriously doubt that the circuit draws 50 amps.  Good to know Advance has them.  Thanks!

Love the post, solves half of the problem that I was looking to solve as well, the APO that I wanted to be RAP was constant and I’ll try switching the fuse tomorrow (too cold out and I’m always afraid of snapping the cover). 

 

Problem two though...  I have a flashing rear-window mounted warning LED bar that I’d like to keep flashing when the power is off and key out, so that I can lock my doors but still have the warning light active and visible. 

 

That means I’d like to have the rear seat APO active at all times and NOT RAP.

 

Since there doesn’t (yet) seem to be a fuse swap for this, I’m considering using one of the “spare” slots and installing a mini USB hardwire kit like this:  (which would also work for a dash cam/GPS if you wan to keep your outlets open, or for a cleaner install)

I have not looked for that but I did notice several of these fuses with female contacts so guess it is possible it can be done.

Finally got around to switching the fuse from one side to the other (position 11 to position 10) and it works perfectly, as hoped and expected.

 

As far as the “six pins” questions some have had, yes this makes perfect sense and is exactly what I would have expected to find.

 

Imagine that the center two pins allow power to travel TO the outlet...  so now there needs to be a power supply to get that power there.  It either comes from one pair of pins that is constant from the battery, or the other set of pins that is RAP, or interrupted when the key is off.

 

Switching the fuse from one position to the other accomplishes that goal.

 

It makes the whole process a lot easier by being able to come here and easily find the fuse location, and a clearer understanding of which fuse is which rather than trying to interpret the manual, but that’s just my laziness talking!

 

Now I’ll continue the hunt to see if the other (back seat) outlets can be altered in the reverse way, from RAP to constant.

But I only saw three pins is the reason I questioned 6.  Maybe these old eyes do not have the resolution required to see 6 that close together. #1 pin to accessory control circuit, middle or #2 pin to outlet and #3 pin to battery.  Don't see need for 6 pins.

To be honest, I didn’t bend down to the angle needed to see if there were only 3, or 6 pins in there. It’s -16° here today, and dirty...

 

But 6 would allow for in/out completion of each of 3 circuits, and while I’m no DC expert, logic dictates that’s a likely scenario. 

 

I’m just happy it worked. I went through the manual again and sadly I don’t see the same simplicity for reversing the rear APO’s.

You’re right. 3 pins. The panel is grounded so the hot is the only circuit required to run through the fuse.

Thought I’d include a better write up and broader picture of what you’re looking for. 

 

In the driver’s side fuse panel, pink 50a fuse is now in position for RAP for the outlet on the dash. It was originally in the other position from the factory, for constant power...  just pull it out and move it over. 

 

Also, for what it’s worth, it’s much simpler to slide the fuse puller on from the side rather than force it over the top. 

 

So glad I found this thread, it accomplished what I was looking for.

    • I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires. 
    • Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉       
    • I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.
    • Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.      
    • About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was.
