Heated Seats
This system allows the electrical heating of the front seats on passenger demand.
The components of the system are:
The heated seat module receives separate battery and ignition feeds and a ground source. The dual automatic temperature control (DATC) module includes the heated seat control buttons and indicators. The heated seat system will function when the DATC module is ON or OFF. When a heated seat control button on the DATC module is pressed with the ignition switch in RUN or START, a momentary ground signal is sent to the heated seat module. Upon receiving a signal, the heated seat module will decrease one setting (the sequence is HI, LO, OFF, HI, etc.). When a heated seat is set to HI, both LED indicators above the heated seat control button will illuminate. When a heated seat is set to LO, only the left LED indicator will illuminate. When a heated seat is set to OFF, neither LED will be illuminated. Refer to Section 412-00 .
When the heated seat system is ON, the heated seat module then supplies power to the heating element circuit. The cushion element and backrest element are wired in series and powered by the same output. The heated seat module will remain on until the heated seat control button is pressed to cycle the heated seat module to the OFF state. If the ignition source is removed from the heated seat module, the heated seat module will enter an OFF state and will not return to ON until the heated seat control button is once again pressed with the ignition switch in RUN. The heated seat module is designed to heat the seat to 37.3°C (99.1°F) in LO setting and 62.4°C (144.3°F) in HI setting and maintain the temperature until switched off. This temperature is maintained by the heated seat module, located under the passenger seat, which monitors the temperature sensor and adjusts the current flow to the heating elements.

The following checks and repairs can help you:
1. In the fuse box within the bonnet - check fuse number 22, if burnt, replace it
2. Check fuse 19 in the fuse box inside the car located under the dashboard on the driverside
3. If these steps don't help, the problem may be with the wiring and connection between the module and the seat cushion - inspect it
4. Check if the signal return on the circuit is adequately functioning - if the module is being informed of an active seat
5. If there is a problem - repair or replace the circuit and/or wiring.

Check fuse 22 in the fuse box under the hood. Then check fuse 19 in the fuse box inside the vehicle under the dash on the driver side. If those are good I would suspect an open in the seat circuit from the module to the seat cushion. This circuit has a signal return which tells the module that the seat is active or not. If the circuit is not complete it will shut off the seat and the light to avoid overheating of the seat and possible damage. good luck

It is usually one of two problems. Either the relay under the seat has failed or the heat element in the seat has failed.
If you are not electrically challenged, you can use a simple volt-ohm meter and check for continuity in the heat element. If you have continuity, the element is good, otherwise that's your problem.
If the heat element is good, you may want to take the good relay from under the passenger seat and put it on the driver's side to see if that fixes it. If so, then you have to get a new relay.
Last, but very unlikely, would be a bad switch.

this is a common problem if you use the seat heater alot.one or both of the seat heater elements will have burned up or broken.where i live it is very cold most of the time and i have replaced hundreds of the seat heater elements.it is rare for it not to be one or both of the elements.

It is the heatling element, stock elements have a single wire snaked through the element and when the circuit breaks it is done, aftermarket elements have a wired grid that if one area fails it still works, they also spread a more even heat.
