Do you feel your seat heaters working? 200

You could try using an ohmmeter as a quick check as to whether current could possibly be flowing through the seat heaters. Test when cold though, or thermostat may be open circuit and prevent a reading. Across the 2 pin connector under the seat, you should read about 4 ohms. If you get a reading, it's still possible as others have suggested, that the thermostat is shutting it down prematurely.

If it's open circuit (again, testing while cold), it's impossible for the heater to be giving any heat. You can isolate the problem to either the seat bottom cushion or the seat back cushion (although with most of the force on the seat bottom cushion, it's most likely that heater):

There's a 1-pin connector under the seat which joins the seat bottom and seat back heaters together (they're connected in series). Disconnect this 1-pin connector. You can test one heater by reading from one pin of the 2-pin connector to one side of the disconnect; the other heater will read from the other pin of the 2-pin connector to the other side of the disconnect.
