I noticed I had the heated rear seat connector behind my drivers side rear seat.  Recently I put an oem wireless charger in my truck and in that process I bought a wiring harness for my center console that supports heated rears seats. 

 

I have a RST Silverado 2020 with a center console.

 

I needed 8 parts to get hardware in place for heated seats

trim plate 84505576 $30

seat heat switch 84476688 $30

heat switch bracket 84172412 $8

harness 84482759 $56

(2) seat cushion heater 84369788 $20ea

module 13523031 $35

module bracket 84180630 $10

seat harness 84441561 $35

 

Total $250

 

I switched everything out and I tucked the heating pads under the seat covers.

I figured it was likely I would need some custom programming but I gave it a shot anyhow.

After all that it did not work. No light turns on the switch.

 

I thought about making a canny device but then WAMS came out with custom BCM programming for T1.  His website says support is pending for adding heated rear seats.   I have everything in place for cooled/heated front seats too but I am waiting to see if WAMS adds the heated rear seats.  Anyone done this? Or made any canny device for any functions on these trucks?

I already have the heated rears, but would love to find a way to add cooled rears as well. I mean it only sucks for the kids, but living in FL, they would be useful 9 months out of the year.

 

I knew the Ram had them, but no way was that enough to get me to switch ??

I've never added OEM heated seats before, especially in newer vehicles that need the BCM programmed for everything.

 

If anyone is looking to do it easy and fairly inexpensive, after market kits are very straight forward.

White automotive and media services WAMS now offers this activation with autosync.  Works just like it does from factory $250 dollar upgrade if you already have autosync, you can use the new console harness from this upgrade to hook up an OEM wireless charger for another ~$120.

I recently purchased all the parts and have everything in except the heating elements as they are delayed. Getting the console harness in was a pain and I haven’t installed the rear harness permanently. It’s currently hooked into the rear connector and I’m sitting at the dealer so they can get the software from GM then install the code. $225 for labor and whatever the charge is for the software from GM, they said under $100. Sure you can go the aftermarket route but I wanted all OEM parts and buttons. Just my OCD I guess. I’ll let you know when I get it working. Disassembling the center console and taking out the rear seat can be found on YouTube.

Well my dealer now says they can’t program the BCM since my truck (LT Trail Boss) never came with rear heated seats. They said my BCM linked to my VIN wouldn’t be able to do it and I couldn’t swap out my BCM. I’m still wearing for WAMS to release their new custom programming service.

      Video processing module location

      By twgraham · Posted

      Can someone tell me where the video processing module is in a 2023 Silverado? I'm getting conflicting results that it's in the front passenger area or the rear passenger area behind the seat.

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.
