Swap 2014 SLE Headlights for SLT w/ LEDs?

So I bought a 2014 Sierra SLE but I had it worked into my deal to have the headlights swapped for the SLT version with LEDs. And by the way, the entire harness under the hood has to be swapped also if you are thinking of doing this.

 

My question is to the guys with the headlights w/ LEDs . Can you give me the break down of when the LEDs are on? From what I'm seeing on mine the upper and lower LEDs come on with the parking lights and also when the projector lamps are on. For some reason I thought the LEDs also took the place of the daytime running lights. Where as my projector low beam currently still acts as daytime just like the SLE headlights. I thought it was the lower LEDs for daytime.?

 

Thanks!

I have them on my SLT. From what I found...... don't hold me to this..

 

when diving during the day - the top LED are on - bright mode.

 

hen driving at night with the any lights on..., headlights, or parking lights, or just fog lights - the top and bottom LED's are BOTH on... but they are dimmed when compared to the above.

That's what I thought too, so I'm wondering if it's a CPU thing. Maybe a flash needed to correct the lighting procedure...not sure?

I really don't know. But I tell you when you try to add / change electrical things like this in these new complex trucks.. you could very well have issues. But the good thing is ...since the dealer installed... they are on the hook to figure it out.

It is likely a BCM program that would normally be specific to the high trim trucks. Good luck getting them to reflash it to make it like the SLT.

I know I was worried about that the whole time, heck they thought it would be plug and play and then they found out the hard way that the entire harness had to be swapped lol.

Like mentioned above, it's their issue to figure out. All I can say is they won't give another buyer the option like I got unless they are ordering the truck straight from GM. They got screwed hard by me on this one. The sales manager said hey we will make it happen! $2k in parts and 8 service hours later....enter foot!

 

I hope it's just something simple they can flash but the way it's gone so far I doubt it lol.

The dealers still don't know anything about these trucks...

example - today I took my 2014 in the dealer to get a small thing replaced in the interior. Just a small finishing issue at the factory. Anyway.. I asked how long it would take... he said 2.5 hours.

In 45 min they were done. Apparently he was assuming it would take the same amount of time as the 2013... but come to find out the 2014 is completely different and this process was a lot faster he said... no sh$t I thought.

Kind of off-topic but I'm really confused why GM decided to make there be different headlights for different trims. I think both trucks look much better with there respective "top trim" headlights (LED's on the GMC and projectors on the LTZ).

 

There's something off about that huge Sierra SLE headlight housing with one tiny little projector in it. The LED's help fill it out.

The LED is an upgrade like all the other things.... and it should only be only on the SLT. Same goes for NAVI, etc, etc... If the SLT wasn't any different... they would all costs the same.

This for sure, I had to find the headlight part numbers and help determine another harness was needed.

I agree and have no clue why they made different headlights, stupid in my opinion, I prefer the SLT headlight and that's why I worked it into my deal. I actually wanted the SLT w/cloth but they had a Quicksilver SLE optioned the way I wanted minus the LEDs in the headlights of course, which is why I'm in this situation. But I'm sure they will get it figured out, the hard part is done, harness and headlights installed and for the most part working correctly. Just have to get the daytime runners figured out!

The GMT900 all used the same headlights from the work truck all the way up to the Denali.

 

They should at least make it an option on the SLE (without having to go All-Terrain).

I understand that... but from GM point of view.. they have to create some difference between the SLE, SLT, etc.. or you would never upgrade.... they would all be the same?

 

Why not put cool LED's on just the STL, AT, Denali... then more people will upgrade = more $$ for them.

 

Why put the cool grill on just the Denali ? Why put the special 20in wheels and cool red/black leather, carbon fiber stuff on just the All Terrain? You can go on and on.... see where I'm going with this ?

In the 800's only the Denali got a different headlight. I like it. I have it, but it was just a 9005 halogen in it. I think if anything different it needs to bebin Denali/High Country territory. And the SLT heads should at least be in the SLE. I always have to have upgrades programmed. It will likely be programming

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
