hi, have a 2004 xj8. have not used seats recently. last time used, all worked fine. used today, switch functions properly, wheel heats immediately. front and rear seats do not heat at all. had taken to dealer during summer and thought did not heat, but he said do not heat in warm weather. had yaw rate sensor replaced previously, which i think is console access. any connectors for seat heaters located in console? fuses look good. any suggestions? thanks a million (the cost of a jag repair)!
