Sorry I'm a little late, I've been in the Caribbean for a little over a week and just getting around to posting pictures. I know there was a lot of fuss of whether or not the SLT lights would so I bit

Well, I finally got around to installing my 16-17 LED headlights. A huge thanks goes out to @zmnypit for fabricating the adapter harnesses.

I finished my installation a couple days ago. I had a Morimoto kit in the SLT halogen projector headlights. My limited use of these LED headlights leads me to believe they are not quite the output of the Morimoto kit in the SLT headlights. But they seem adequate. I like the reliability of led.

I just purchased these. I been following along with most of the post. I do want more info about the harness needed to make the DRL shut off when turn signals are active. Do I still need to purchase the Gen5 harness or Is there another harness that I can buy that is plug and play, that will control the DRL w/turn signals?

Since you have an SLE you will need the Gen5 harness.

Anyone had low beam issues with the light not coming on? Local guy got in touch with me yesterday after buying a 2015 2500 denali that already had the swap done. It looks like a gen5 or plain&simple harness not sure. The drivers side low beam will not power on with that harness or my adapter however the bright light will.  I took the light and ran a jumper to the battery and the low beam will power on like that. Everything but low beam works so I'm scratching my head. Using a test light its getting power all the way to the light so it has to be in the light itself. I ran out of daylight so I didn't get to swap sides to see if I could rule out the light.

Is there power through his harness to the low side? When you said you jumped power into the low side pin did you use a harness? Or run a wire directly into the low pin?

 

it sounds like a worn pic connection lamp side (if you have power to it) or a broken wire in the main truck harness.

Yep. All the way to the light. I jumped both the light and the existing harness. Main truck harness is getting power at the factory plug as well. Low beams will not power on though even though it gets power. Pass side works fine.

He's supposed to find out where the lights/harness came from then check with whoever. I'm not certain who's it is to be honest.

Are you saying that power is there for the low beam at the OM wires, and if you connect to the headlight only (no other harness) there is still no low beam?

Well I cant connect the headlight with no harness because of the plug differences but yes thats correct. On the OEM fat plug I get power on the low beam, Add either my adapter or his harness and I get power on the low beam on the newstyle plug.

Got it, here is the good and bad of the new LED headlight, Good is there LED for both the Hi and Low beams, the bad is there LED for the Hi and low beams, so we think the computer on the headlight went bad, and lost a circuit in side that controls the low beam, looked it the one we opened here at the shop, it runs all the wires from the LED board to the computer on the side of the headlight.

      Doors lock and mirrors fold in while driving

      By BIGBOYS · Posted

      I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again.  Any advice, thank you,   Ed

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

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.
