My drivers seat was F'd up too. I pressed the button to turn on the cooled seat function. The fan would start, then slow down and then I could hear a relay click and it was off. Heated seat function never turned on. Took it to the dealer and they had to replace the innards of the seat related to the heated/cooling feature. $1000. later and all is back in working order. (my '06 is no longer under warranty.) Only has 40,000 miles, I gave the dealer an earful about the seat failing at said mileage.
