@dspa So after all this, are the AsBuilt changes (and attached TXT) you shared in post #29 for your 23-24, all we need to do? Or did you find other line items that need modification. I understand there is no correlation or sense made of the plain english settings, and messing with those will only break things. But given I have a 24 Platinum 6.7 with Supplemental Heater, I would assume my needed changes should be the same as what you have done. Does that sound about right?
Below are my Super Duty's as-builts, stock from factory, before I started this project. Compare them to yours (lines 733-01-01 through 733-01-13). If all the digits match, you're good to go with the text file I posted in #29. Change the .TXT extension to .ABT before importing. Then go into plain-language HVAC configuration and enter your correct VIN. That will update 733-02-01 through 733-02-04 to the correct values.
Since you have a 2024 Platinum 6.7 with a PCT heater, your as-builts will be very close if not identical to mine. My post #29 file will technically work even if you have a different digit or two, but I'd imagine you'd like to know what's different. In that case, get with me and we can figure out what needs to be set differently in your 19980-K module.
One other note regarding the cross-reference of values...
The keen-eyed among you may have noticed that my Super Duty as-builts had 00, 00, and 00 for the front heated seats high, medium, and low settings, but I carried over the values of 82, 50, and 36 from the original F-150 as-builts, instead of changing them to 00, 00, and 00. The seat heaters seem to be working properly with these values. If I find out something different I'll be sure to post it here.
Well I can't thank @dspa enough. I put back in my LCD button HVAC module in my 24 Platty 6.7 and after doing all the changes in his attached txt file (yeah I manually put them all in, I know I could have imported the ABT, but I wanted to see what everything was) my LCD HVAC module works perfectly. All buttons do what they are supposed to.
I'm now $300 dollars lighter as this was a mod I've wanted to make since I bought my truck a year ago. I'm anxiously waiting for the HVAC controls to arrive. Somehow I suspect Ford is selling a few more of those than normal.
But I'm grateful to all that have contributed to my forscan knowledge and helped me make my truck mine and exactly how I would like!

@RayoVac Glad it's working for you! I think it's a pretty straightforward mod, if not a little time-consuming, once you understand what does what... wouldn't you agree? It just adds a lot of class to the center stack, I think, and those ***** don't seem so needlessly large, anymore. Additionally, I know a lot of people find the temperature readouts in the screen sufficient, but for me, being able to glance at those high-contrast readouts in the ***** while turning them just feels more natural.
@Turniipp Muahahaha... my evil plan is working.
Your comment made me chuckle... Yeah, it's a pricey mod, but those temp readouts sure are pretty, aren't they? I think you'll feel it's money well-spent once it's done. I'm right there with you - this was the thing I missed most about my F-150 when I traded to the Super Duty (edit: it's the only thing I missed... the Super Duty is superior in basically every way ). I tried for five months to live with it, but it just wouldn't stop pestering me. So, on a wing and a prayer, I bought a brand new 19980-K module with no idea if I could make it work. I rarely take risks like that, but I just missed the LCD ***** so much from my F-150, I was willing to spend the money to try and get them back. I also figured I could re-sell the module if it didn't work.
I can't thank @Livnitup enough for his spreadsheets. None of this would have been possible without them. @ngiovas started the thread and gave me hope I wouldn't be the only person out there crazy enough to try this swap. I still think it's fortuitous he and I were attempting this at almost the exact same time. And of course I can't forget @Don Ridley who was always there with some encouragement when I got feeling dismayed. Okay okay, I'll stop saying my thanks and get off the stage, now.
One last thing (for now) -- regarding what I said in post #47 about the seat heater high, medium, and low values -- I did a more thorough test of the front seat heaters today. With the F-150 values of 82, 50, and 36 loaded into my module, while driving, I ran at each heat level for 10 minutes. My butt-thermo in the driver's seat would categorize the temps as high=hot enough to get you toasty quickly, but you probably won't want to stay here long-term; medium=nice and warm but not unbearable - a good middle ground; low=body temperature, just enough to be noticeable... the heater is on but it's basically maintaining me where I am... probably would be more noticeable in a very cold cab.
On the passenger seat, I took several measurements using an IR thermometer on each setting and in different parts of the seat and lower back. Low was about 80F, medium was 95F, and high was 125F. These were the highest temps I could register over different parts of the seat and lower back at each temperature setting. They probably would have gotten warmer with more time. The temperatures vary widely from spot-to-spot, and are also lower than what you'd experience actually sitting in the seat, so although unscientific, it's enough to make me pretty happy with the settings. I thought about setting them all to '00' in FORScan to see if it behaves the same way, but not sure I'm very motivated to do so at this point. For whatever reason, my Super Duty's stock as-builts were, as I mentioned before, all '00' for the temp settings. Maybe in the Super Duty, the HVAC module doesn't control the temperature, but instead just sends on/off signals and the temperature is controlled elsewhere. I just don't know. If someone wants to try importing 00's to the following locations and see if the front seat heaters still work properly, I'd be interested to hear your results:
Well, I finally got my HVAC module installed and fully updated this past weekend. I had hoped to get it done sooner, but really glad I finally did it. Such a small change makes a big difference (in my mind at least ). My wife's response was, "Tell me again why you needed that?"
Thanks again @dspa for all of the hard work. This will benefit many people in the future who decide to make this upgrade. I just wish you had a '25 so I could convince you to help me figure out what needs to be changed to add the top of tailgate camera and backup sensors .
My wife gave up a long time ago trying to understand why I do the things I do.
I saw your thread from December asking about a retrofit and discussing the recall. I honestly thought Ford had resolved this recall, already. Regardless, if the wiring is present, it's probably just a matter of getting the parts and doing the ForSCAN coding changes. Figuring out what those coding changes are will be the challenging part.
I really like the feature, but do worry from time to time if I'm going to end up having issues with it. At least it's a known issue. Some people like to give Ford a hard time about all their recalls, but I'd rather a mfg own up to shortcomings and fix them than see them hold out on a known issue until forced by a regulatory body to issue a recall (been there, done that, got the t-shirt).
To everyone viewing this thread, I just want to clarify a couple things…
1. This thread ONLY covers installing an HVAC module from a 2021 F-150 with LCD display ***** into a 2023-2025 Super Duty. The module is also compatible with 2022+ F-150, but Ford only gave us the LCD ***** in 2021.
2. The Ford part number for said module is ML3Z-19980-K. The part number on the sticker on the back will be different. I have seen ML3T-18C612-DEand ML3T-18C612-DF. There may be others but I’m not sure. If you’re buying new, order ML3Z-19980-K.
3. I cannot help with programming modules for Super Duty trucks prior to model year 2023 (for example: a 2017 truck with a 2022 dash swapped in). I’m sorry, I wish I could, but I have zero experience with anything prior to 2021+ F-150 and 2023+ Super Duty. I’m not saying the info isn’t out there, just that I’m probably not the right guy to ask.
4. I am still doing long-term testing on my module swap. I have found no issues so far, but I will absolutely post here if I do.
5. If you do this swap, and you need warranty work done on your HVAC system or any component related to it, I’d highly recommend swapping your stock module back in before going to the dealer. Don’t expect Ford to not try to void your warranty based on this mod. Magnuson-Moss says you’ll be okay. Real world experience by many customers over the years says different. Up to you whether you want to chance it, but you’ve been warned.
