Thanks for the reply. Can you explain the relay part of it? I hear "flipping" or the "engaging" sound for both of the seats when the heated or cooled seats is kicked on, but the passenger seat works fine, so how could one tell if it's faulty for the driver's seat? Also, I do not have heater coils on the bottom of the seat. I have taken it apart before when replacing the cushion and no such coils exist except for the springs on the bottom to hold the cushion and driver up. There is however a blow vent right beneath the cushion where a hole must be cut in the cushion to allow (my guess would be air since I feel it moving and blowing around right in the center). Could there be heater coils in that, and then air would come through as hot air?
Thanks.
