Can anyone tell me if these are factory mirrors for my SLE? or how I would go to find such a thing? I don't have a build list, as I bought this as a used Certified GM truck.  I took it in because the turn signals do not work on the mirrors.  I have a year bumper to bumper warranty on the truck and wanted to get them fixed but they told me that they are after market mirrors and they will not cover after market mirrors.  Every 2500HD I have seen has these type of tow mirrors on them.  It is not a big deal that they don't work but I figured if they are suppose to work then I would like to get them to work.  Thanks

Does the Dealer have other 2500s on their lot so they can point out what the difference is. I have a 2016 Chevy LTZ Z71 4x4 and they look like mine.

Some trucks don't have the wiring harness in the door to make them work. On some of the 2015s built after a certain date you can change the harness and they will work. Other 2015s built before that date require significantly more work to make the lights on the mirrors work.

 

On my 2017, I had to change the harness in both doors to make all of the lights work.

Does your glove box have an RPO sticker? If so, snap a pic and post.

GM did produce a 1st Gen “DPN” Mirror (just like these pictured) for some 14 and early 15 model HD trucks. My guess is previous owner installed them needing only the mirror to function and didn’t take the steps to get the turn signal to work. It could be a factory mirror but didn’t come from the factory with them.

Yep. So the DL8 code is the factory mirror it originally came with. That is the smaller mirror with just power adjust and heat.

So if you want the turn signal to work, you’ll have to either swap the door harnesses, or modify the harnesses that you have now.

Yes. Complete door harnesses are $285 for the set shipped. Then I refund $100 if you send me your factory harnesses.

You're pretty much the coolest person on this site. LOL! thanks for all your feedback I definitely am interested in doing this but I am still wanting to do the center console swap yet too. I need to figure out my priorities I guess.

I bought the factory door harness from GM parts direct for my 2017 for about $130 for both doors. Super simple to swap, they even had all of the pins on the harness and everything so it matched up exactly what would have been from the factory.

If I may...

 

I added that exact mirror to my 2015 SLE 1500. Turn signal didn't work, but power/heat did.

 

My 2015 Silverado 2500 has the newer, square tow mirrors. Came as-built.

 

Having had BOTH arrangements, I am NOT convinced having the red LED's blink is worth spending $130+ on a door harness. Honestly, I think it'd be more useful if the amber LED flashed with signal. I suppose others can see the mirror arrow when it blinks, but really it just faces the driver for the most part.

 

Good luck with whatever you do with it!

      5.3 / 6.2 valve covers / oil burning

      By FiLo · Posted

      Any update if the new valve cover help with the oil consumption?  I have a 2014 GMC sierra and my truck is consuming a lot of oil so I’m wondering if replacing the driver side valve cover will stop some of the oil consumption. Thanks

      I bought belts and pulleys for my '20 L5P at Rock Auto a couple years ago. I have used them for many years, and almost always save significant money, especially when I buy maintenance stuff ahead of time.   They carry many OEM parts, which is all I use unless an aftermarket is shown to be same/superior, or if it is an insignificant part or unavailable OEM part anywhere else. RA is usually lower priced, often by a bunch, but parts are sometimes unavailable or out of stock, and I do shop around and sometimes find better prices at other sites.   Be aware that you pay shipping, and if you buy multiple items and they are coming from different warehouses, the shipping can kill the advantage. Planning ahead is best if possible.   If you have a transmission service in the near future, check out their OEM (AC Delco ULV) fluid, usually MUCH less than anywhere else.

      10L1000 anyone with High Mileage ? I hate Damocles....

      By Deadwood · Posted

      New member here, very long time occasional guest. Saw this thread, thought it would be a good time to contribute someting. It is only my experience and not a claim that everyone will have the same.   I bought my '20 3500 L5P new and have put 99.9% (literally) of it's current ~400k miles on it myself, with over 50% of that towing loads between 4k to 15k, and to me this truck has been nothing short of amazing. For the first 235k I had zero issues, and from there until 321k I replaced a NOx sensor, two failing glow plugs, and three of the notorious injector connectors. I believe this truck is in part, a testament to good luck, but also good care and following a decent maintenance schedule (I also keep meticulous records.) As a result, it looks as good as a well cared for 70k rig, up and down, inside and out.   At some point before that 321k mile mark I began to get a little spooked about the 10L1000, especially the valve body. Word of mouth about potential issues prompted me to jump on the net to sift through all the noise and determine what all the fuss was about. I routinely take long trips, coast-to-coast and points in between, so roadside breakdowns can be '...a thousand miles from nowhere' and a bit of a challenge, and though I had no issues, my guard was up and activated.   And then I stumbled across a chance to salvage some parts off a new 2025 that had been wrecked in transport. I grabbed a few wear items (alternator, pulleys, etc.) and on a whim asked what the ten speeder would cost me. It was cheap...really cheap. I knew some changes had been made in the '24+ version 10L and were supposedly not compatible, but I called service/parts at my local Chevy dealer and asked why and they didn't know. A call to a well known aftermarket transmission outfit revealed it was very likely it would be fine, but to them not 100% sure.   Because it was cheap (really cheap) and I was spooked, I took the chance. Had it installed by a local shop and it worked like a champ, shifted just like the original. At it's first service at 37k, I had the shop put in a Next Gen valve body kit, which after some initial hiccups and rough shifts, smoothed out though with somewhat firmer shifting.   All that said, I have a very serious concern about my newer transmission as just two weeks ago it suddenly began to exhibit a strong reluctance to engage forward or reverse. It was a bit past due anyway so I took it in for service. The reason it was sticking was due to 'glitter' in the fluid clogging the filter...not good folks, often indicates a converter giving out. We ended up going ahead with the new filter and fluid, first to see if it would move and shift, and then if so buy me a little time. It did, and I've driven it over a thousand miles and it is shifting smooth, no noises or slipping. Regardless, it looks like a third gearbox is in my future so I can resume taking long trips with some confidence. In the very short term, my curiosity will have me examining the fluid to check how much glitter has reappeared.   An earlier poster had alleged, in the context of 10L100 failures, that it is another example of how we seasoned citizens somehow descend into hysteria, lose control of our senses, and react irrationally after brief encounters with the idiocy of the internet infosphere. Let me say (and I have used and abused said internet since it's infancy) there is no segment of the populace that has a corner on over-reaction to digital garbage. Just as my offering of experience in this arena is purely anecdotal and should not be considered gospel or all-encompassing, I believe it is still worthwhile information to consider, along with other relevant anecdotal experiences about things like complex transmissions, especially when balanced with other sources.   So to answer the original question, yes I got high miles out of my first 10L, trouble free for 321,000. Now I really wonder how much longer it would have went. Did I 'overreact' to the internet ghouls by replacing a 'good' one with a 'bad' one? Maybe. Who knows, the thing might have taken a puke a 100 miles later. So I'll just fix it again, then move on and start thinking about all the other stuff that will eventually wear out. It still has the original brakes (they're at ~60%), original injectors/pump, turbo, water pump, etc....pretty much original everything. Knock on wood.

      6 Speed vs 8 Speed

      By swathdiver · Posted

      At peak temperature.  They get to cool down and warm up more, especially those with the external cooler.  I have three GMT900s and one of them has over 225K on its original transmission.  Fluid gets changed about every 36K miles, all of it.     It's not the bean counters, it was the government.  They had to meet CAFE standards and other government requirements.   To get around that, we tune them and modify them to our liking.
