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.

Has anyone else figured this out?  WAMS replied to me that they don't have this capability....

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.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.

      Parking Brake - Automatic Engagement Questions

      2023 GMC 3500 HD, SLE, 6.6L Gas, 4x4, 6 Spd Options:  SLE Convenience Package; Driver Alert Package 1; Spray on Bedliner; X31 Off Road Package; TRAILERING MIRRORS, HEATED POWER -ADJUSTABLE, AUTO DIMMING, WITH TURN INDICATORS WHEELHOUSE LINERS, REAR INC. REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.
