OEM heated seat upgrade

So I'm aware that you can purchase heat pads off Amazon and wire them to an aftermarket switch, but I'm curious if you can swap the OEM non heated for OEM heated seats and if they are (relatively) plug and play. So far I have found the following; You would need a new dash bezel including the switches, but do you have to replace the entire "heater control" panel (Which includes the a/c and climate control switches) or can you just swap the upper portion where the hazards and seat heater controls are? If it is the former than I don't believe it will work because the climate control buttons are different than the a/c buttons without the tech package. I have an ACLB and didn't want to pay for a tech package when all I was really interested in was the heated seats. Also, I live in FL so they're not much of a necessity here, Frankly the only reason I'm interested in adding them is due to my lower back pain on longer drives.

 

Might just be easier to take it to the upholstery shop and fix the seat itself. I have read and plan to the seat mod myself. Can add about an inch o cushion to the rear and level it out. Or the horrible way of adding strut bushings under the rear seat mounts. Need longer bolts and to oval out the mounting hole. By raising the rear portion of the seat you do lose head room but it removes the pressure being put on the legs from string a virtual hole.

 

If you ONLY want lower back heat you might get be better off adding aftermarket heat to your seats. The stock heated seats get toasty on the seat pan as well as the whole seat back. It might be too much heated area to achieve your goal of heat relief for your lower back.

 

An upholstery shop/aftermarket heater solution will be way less expensive than trying to cobble together OE parts unless you find a donor truck.

And with OE parts you'll just have a warm seat that is still ill fitting.
