The coil is probably bad. Usually the driver seat is the first to go. all the seats in mine work fine, except the driver, and i would have to believe that is from constant in and out of the car.

What is inv;oved in fixing this problem? On mine the drivers doesn't work.

If the element is bad, you have to remove the seat cover and replace it.
