Hey guys, 

 

I ordered a leer 100XL topper for my 2021 3500 AT4. I installed it myself. It wasn’t difficult with the help of a few friends. The wiring was a little more tricky. The 100XL comes with the remote window lock feature. That was the tricky part. After a few days of research and development, I finally figured out which wires are the lock/unlock wires. If you take apart the drivers door sill, there is a covered wire bundle there. In that bundle, there is a 20 gauge gray wire and a 20 gauge brown/yellow wire. Those are the lock/unlock wires. Hope this helps people in the future so you don’t have to beat your head against the wall like I did.

      Ac not keeping up

      By Aimatdeer · Posted

      2024 l8t . Ac has never felt really cold even new. But lately it seems a little warmer. When it gets in the upper 80s and a little more humid it just does not keep up. And sometimes at idle it gets warm. My wife's 2008 envoy is better. My son's 2016 is colder. I have an apointment for a third try Monday the 29th at a third dealer to try and get cold ac before my warranty is out. The first two told me something about so many degrees under ambient temp blah blah blah seemed like they didn't want to mess with me. This was set at low. Max air fan speed high. 87 degrees and a little humid.   .

      OCI, not when but why?

      It isn’t all that bad in the world with purchasing power versus quality. My first car had just basic equipment. My oil choice was conventional oil. The life expectancy was around 100K miles. During that time you could expect to change all the accessories. Today with inflation you can buy the equivalent. It comes fully loaded with 4 doors. The life expectancy passes 100K miles replacing no accessories. If reaching that milestone is your goal you simply follow the recommended service intervals. If you want more miles simply do more maintenance. When in doubt you can check the internet or YouTube for information. The selling of any product hasn’t changed since the beginning of time. The power of the buyer has. The price of the product hasn’t changed much with inflation. The buying public wants more. Competition and the buying public has put the sellers in a box. The greed is on both sides. You can still get more for less. You just have to do with less. That used to be popular. The buying public has changed . It’s the sellers that are trying to keep up. As Grumpy tries to inform the readers in this case with maintenance. If you want more. More effort is required. That information wasn’t available this easily just a few years ago. I believe the public has more power. Getting information is easier.

      2023 DRW Wheel Liners

      By SFC Retired · Posted

      Gentlemen, I'm new to this forum. My question is, I thought I have read somewhere that the rear wheel liners for 2024- 2026 GMC Sierra HD3500 DRW can/will fit the 2023. I can't seem to find that information again and wondering if anybody has any knowledge if these will work or not with the 2023? Part# is 84892542. Thank you for any information. The GMC parts counter wasn't able to give my any definitive answer?

      Spacers aren’t safe anyway, so you’re better off just buying something else.

      OEM Trailer Hitch Receiver - Impact tightened by shop

      Its because they have thread locking compound on them. I would bet money that they are actually reusable and not a literal TTY bolt because GM and most other OEMs don't trust techs and the end-user to apply thread locker properly in the same way they don't trust anyone to solder properly (and instead instructing crimps everywhere). Torque To Angle =/ Torque To Yield.   If you think dealerships or any technician replaces every 'discard' bolt in every procedure, I have a bridge to sell you.
