Hey guys . . . according to the Crossfire Specialist Student Reference Book . . . I quote on the Heated Seats

" The heaters may automatically switch off due to HIGH electrical system demand or a low battery. When this occurs, one or both indicator lamps blink (depending on selected heating level) until enough voltage is available."

That is why when it is really cold and you start up the car, with a low battery and switching on the rear defrost, you get the blinking lights. I would suggest you let the car run for a bit before hitting the heater switches ! I don't drive my car in the winter, so have not encountered this issue. . . .however, I did recall reading it . . .

Just my two cents worth . . .

Cheers
