My driver seat developing a rip, the back part of it doesnt completely close and only the back part of the seating works. Butt part turns off after 30 seconds or so. I say all this because down the road, instead of repairing these things, might just try to replace/add the cooling feature that the LTZ and Denali/Escalades have. What would be needed to do this? I'm thinking the buttons on the door card along with the seat and a module I assume? Just curious how much work to add cooling to see if its worth the project, especially if your seat is missing tons of features or in bad shape.
