It sounds like the drivers seat control module has gone out which is common, but to make sure lets check for signal from the module to the seat heater element before we replace it. Here is a guide to help you do the test:

Below are the wiring diagrams and module locations fro both the drivers and passenger seat.

Check out the diagrams (below). Please let us know what you find.
