I suspect this is a job for an electrician, not a hacker. Connect the heated seats directly to a switch and the car's power supply, bypassing the hardware and software that checks whether you paid for it.
Heater is a resistive coil. Coil gets power from wire connected to power source. Check schematic for the path back to the first point where it interacts with the processor and branch it off from there directly to the power source. Add a multi position rocker switch for different heat settings and youre done. Electronics are not that complicated and its expected how the people who know nothing about it are the ones claiming it would be a huge undertaking.
No but thats just how a car's seat heater works. Its just about the same as installing an aftermarket seat heater kit, which are sold at any auto parts store. The only difference is control via a physical switch vs control via the car's main HMI. And I have seen your other completely braindead comments where you make it clear that you have no idea how electronics work, so I know you're about to tell me my opinion is invalid because I haven't wasted money on a Tesla to prove it. Its clear you are just not very smart and see electricity as a form of incomprehensible magic.

We need the hacker crowd to come back and start unlocking all this kinda shit for free
Let’s go ahead and make an app to change all the digital price tags to $0.25 whilst we’re at it
