2018 Suburban, heated seats don’t work. Not necessary now, but wife will want them soon enough. When you push the button, the red light flashes, all the yellow lights light up (like it’s coming on), and.... nothing. It just goes like you never hit the button. I’ve been all over under the seat and everything is hooked up. Any suggestions? It won’t most likely be covered under warranty either.

 

Welcome to the forum. Should be covered unless you're over the mileage limit.
