I have a 2006 Lincoln Town Car. Both the driver and passenger heated seats will not work. If I turn the key on and press the heated seat switch it stays lit for less than 1 second then goes out. If I turn the key off then back on, I can recreate this behavior on the passenger side switch both high and low and the drivers side, both high and low. Fuses are all OK. Is the problem the seat heater control module?
