So I'm trying to do the heated/cooled seat retrofit in my 2017 silverado 1500 and I've found a lot of stuff online about how it would be a whole lot of work because of all the extra wiring that the system has, & that it would be almost impossible if you didn't have heated seats to begin with, but I don't accept that & I am determined to make it happen. I've already bought every bit of interior out of this high country which came with the heated/cooled seats, but now that it comes time to actually do the swap I realize that I probably should have done a little more research before spending this much money on this stuff because If pgamboa is correct that means I just wasted $1500, but I'm determined to prove him wrong(no offense if you happen to see this lol). So I guess My main question is, has anyone been able to do this retrofit successfully, to where the heating, cooling, and power all work as designed & so there aren't any airbag lights or other warning lights/messages on the dash? I'm a technician at a gm dealership so I have access to all the wiring diagrams and oem information that I could possibly need, but I'm a little confused as to the hard parts that I will 100% actually need,& I haven't heard of anybody actually doing this successfully with everything working as it should, so I want to make sure it's possible without wasting a whole bunch of time on it to figure it out. The other main concern that I know will need to be done for it to function properly, and the thing I'm most concerned about figuring out, is the programming aspect of it. Obviously the truck will need to be programmed in order for the system to function, but im not quite sure on how to go about doing that, especially since I'm going to be adding new modules entirely since my truck didn't have heated seats to begin with, but would there not be a way to avoid having to do that & just running power and ground to the heated/cooled seats, but still using thd factory buttons to retain the oem look? I mean their pretty much just toggle switches, so really in theory, for for the low setting heat I would think I could just install a resistor between the switch & seats, and could do away with the need for all the modules , I just wouldn't have the memory features or comfort/convince settings that I would if it were programmed correct? That is obvi a worse case scenario type situation if there's just no way to make it work with an aftermarket programmer or something. Which everyone always says something about how if you go that route & end up taking it to a dealership or something & they reprogram the bcm then it would take away all the other features, but since I work at a dealership I can make sure it never has an mdi hooked up to it. It'd be nice if gm would let you program any module to your vehicle if all the appropriate hardware was there & whatnot I really don't understand why they don't allow that, but apparently it's above my pay grade lol. But if anyone has any info om this, or better yet if angone has actually SUCCESSFULLY done this, please help ya boy out with some info! Please & thanks In advance!
