Make sure you first check every fuse in the car and under the hood.If every fuse is good then its either the seat heater control module located under each seat,or burned out heating elements.The mirrors could be a faulty switch.

stay away from the front drive continental, the seat is the least of the problems on those cars. they have bad air ride suspension systems, and weak transmissions DO NOT BUY IT buy a towncar instead

I have the same problem. Seat and steering column just stopped working. Passenger side normal. No fuse for these components. With so many postings witht he same problem there has to be a defective or worn out source. Please post if you find a solution!

you may have shorted them out if you did not disconnect the battery when replacing the alternator did you check the fuses under the hood as well as the ones in the car? get a 12volt tester and see if you have power coming to the seats and if you don't there could be an open curcuit somewhere open the hood and make sure everything is Ok and that there is no plugs to the fuse box off under the hood

Possible iginition module, Safety nutural switch would not allow the car to even turn over.
