HEATED SEATS INOPERATIVE
Ford:

ISSUE
Some 2005-2006 Freestyle, Five Hundred, and Montego vehicles built through 11/22/2005 may exhibit a non-functioning heated driver's seat. This may be due to seat cushion heater harness becoming trapped between the track torsion bar and the cushion when the seat is in the rear tilt full down position. This may cause the solder joint at the seat heating pad to separate.
ACTION
Replace seat pad with new part and reposition harness. Refer to the Service Procedure.

There is a built in block heater, cord sticks out under body almost in front of driver.
if it has rear heat and air it has a heater coil in the back driver side check hoses to it and heater coil itself
If it has a block heater the cord will be somewhere on the front of the car, easily accessible. Unless it is a Canadian car or it was ordered as an option it will not have one.
