I just got a new '08 and there is a switch next to the lumbar, seat adjuster, and manual recline. It has the picture of a seat and two ~ lines on top and one ~ on the bottom. I checked the manual thinking it was heated seats and it says that the heated seats switch is on the door not where I'm talking about. Its 95 degrees out so I cant quite tell if its heating the seat or if its just hot from the weather and me sitting on it. Thanks

 

welcome to the forum!!!
see if you can post a pic of the button that would help a lot

 

There are 3 different power buttons on the side of the seat in this model year vehicle. The Power seat which will tilt and move the seat forward and back and is furthest forward on the seat, Power Lumbar which as is implied changes the amount of lumbar support in the seat and is farthest back on the seat and the power reclining button which is in the middle and controls how far back or forward the seat reclines. These are the three buttons on the seat as far as power options go. The heated seats as you stated should be located on the doors. If this is not how your vehicle works then I would suggest speaking with a dealership and possibly rechecking over your owners manual. Specifically, section 1 pages 3 through 6 for the power and manual seat functions. I hope this information helps you.
