I was helping a friend trouble his cell phone and auto charger in my truck. I used the right side accessory outlet on an SLT model. His charger

did light up and the phone was charging, then the charger light went out and the phone shut off. I tried using my Motorola charger in the right

side and it also would not light up. I tried my charger in the left accessory socket and it worked fine. On the right side it would not.

I checked the right side socket for any damage or shorting and saw nothing. Left socket has power, right side and rear console socket do not.

 

What is the fuse number for the Diesel fuse diagram. The owners manual says the accessory circuit is 20amps. I do not know if there is

a 20amp fuse or each side or are both accessory sockets on a single fuse.

 

The fuse number is 50 for a diesel (Lighter/accessory sockets). I checked the fuse and it is good. I have also found the rear console accessory socket also has no power.

 

WITH A GOOD FUSE, HOW IS IT THE RIGHT DASH SOCKET AND COUNSEL SOCKET HAVE NO POWER BUT THE LEFT SIDE DASH SOCKET HAS POWER?

my left one is out on my 07 gasser as well, waiting on a location

 

 

The owners manual shows a fuse description and location guide. The gas is different from diesel. The fuse is called Cigarette Lighter/Accessory outlet.

The 2008 NBS diesel fuse number is 50, and is a 20amp fuse in the engine fuse box.

I am describing a 2008 SLT.

 

The gas and diesel have different fuse locations. Check your gasser owners manual. The left hand dash recepticle is fused from under the hood in the

fuse box. The right hand, inside console and rear of console are fused from the panel behind the removable left dash panel when the door is open.

Both fuses are mini-20amp.

 

My left recepticle continued to work since the fuse in the under hood box was OK. The right recepticle and inside console and rear of console did not

work due to a burned out fuse in the left side dash fuse box.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
