I had the same issue with my 2004 XUV on the drivers side. Noticed that a "spot" was hooter than normal right before it quit. The seat heaters are basically a simple wire coil that is laid between the upholstery and the padding. The back and seat units are independent but operate off the same switch. If you are somewhat mechanically inclined, this is not a difficult fix, you just have to be patient and careful. Mine was a year ago and I think the replacement part from GM Parts Direct was less than 50 bucks. The dealer wanted over $300 to fix it. If you want me to walk you thru it let me know.

there may be a software issue, there is a reprogram for seat heater issues. Bulletin 05-08-50-008 may pertain to that, a AC DELCO Shop or the dealer can ck that and see if this bulletin applies.
