Start with http://quasimotors.com/.

Basically, the controller in the dashboard has some circuitry and a relay. The seat has resistor wire and a sensor. The adjustment on the controller selects a temperature. If the seat is colder than the selected temperature, the relay closes and puts 12 volts on the seat heater. Once it warms up to the selected temperature, the relay opens. The seat temperature drops, and the cycle repeats. Hotter just means the relay stays closed more.

In 90% of the cases, a bad seat heater is due to a broken resistor wire in the seat. And most of the time it is on the seat bottom, on the front outside edge. That gets the most abuse getting in and out of the car. You can check by moving the seat forward, and using an ohmmeter on the seat heater wires in the connector under the seat. Yes, there are a bunch of connectors under the seat. Look for the 8 pin connector. Pin 5 will have a black wire, pin 2 a yellow wire. With the car off, measure resistance between the fat yellow and fat black wires. If it's a few ohms, the seat heating element is OK and the controller may be at fault or you've got a bad ground. If it's an open circuit - and it usually is - the heating element is open.

See Quasi's page. You can pull back the seat cover, find the break, and solder it back together. the break is usually very easy to see - when it breaks, there is a little arcing, leaving a burned space in the foam. Solder it back and you're good to go. With older cars, I need to do this about every 18 months or so. No big deal.
