The seat heater should have some type of thermostat in the seat that regulates the temperature. I would check that the thermostat is operating properly. You should have the factory repair manual for info on how to diagnose this system, you can look here for a free manual: http://bit.ly/autozone_repair_info or go to http://bit.ly/alldata_repair_manuals, http://bit.ly/8Aj82P or http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
