The heated seats for the front driver and passenger don't work

Are the connectors actually wired the same? Check the wiring diagrams for each seat if you can find them, otherwise trace the wiring from the internal components in the seat to the connector and make sure the heaters are going to heater power pins in the original harness, and temperature sensors are going to temperature sensor pins (temperature sensors may be polarized, that is, it makes a difference which pin goes to positive and which to ground).

The heated seats are a luxury feature that heat the front seats. This provides maximum comfort for the driver and the front passenger. To turn on the heated seats, press the heated seat button, which is a picture of a seat. There are two of these buttons, and each are located on the center console. The button on the driver's side of the console controls the heat for the driver's seat, while the button on the passenger's side of the center console controls the heat for the passenger's seat. Pressing the heated seat button will turn the heated-seats onto their highest setting. Pressing the button a second time will lower the heated seats to their medium setting. Pressing the button a third time will result in the lowest setting. Pressing the button a fourth time will turn off the heated seats. There are three lights next to the heated seat buttons to indicate what setting the heated seats are on.
Tip
The heated seats will only work when the engine is running.

Electronic's ! drivers Power seat module , driver door module . Do you know anything about automotive electronic's ?

The heated seat module (MSM) controls heated seat operation for both the driver and passenger seats. There are 2 modes of operation available for heated seats; both the seat cushion and seat back heat, or seat back only heat. When a heated seat temperature signal request is received, the MSM will activate both the seat cushion and seat back heating elements. When the heated seat BACK ONLY mode button is pressed once the MSM will deactivate the seat cushion heating element and leave the seat back heating element ON.
The adjustable pedal system is controlled by the memory seat module (MSM).
your best bet , have a qualified repair shop check it out ! Could have DTC'S - diagnostic trouble codes in door module , BCM etc...

The most common cause of this problem is that the drivers seat heater grid is open or burned out. That is based on 25 years as a Ford dealer technician.

Replace the fuse with one the same rating. If the seat now works.... smile. If the new fuse blows or the heat does not work you may have a short (or a broken wire) inside the seat that's causing the problem. It's an 11 year old seat.... tearing it apart to find the source may not be worth it.

reconnect and the connect back the cabel joint under ther the driver seat

I have a 2006 land rover lr3 hse my driver seat and mirrors and cooler in the center stopped working all fusses look ok what could be the problem please help thank you

you need to check the resistance in each of the heated seat elements in the seat. There's a two wire connector under the back of each front seat. The connector should be green. disconnect it and measure the resistance along the circuit going into the seat. if it isnt .1 - .3 ohms, replace the appropriate heated seat element

your heater element in the seat went bad,the dealer will have to do this because the seat has come apart the cover wether it is leather or cloth.
