First, are the heated seats a factory option on your vehicle or are they aftermarket? Sorry, I'm not sure what options are available on your particular vehicle... If you give more info on your vehicle it might help in determining a fix.
You mentioned you checked the plugs and they have voltage from the switch. When you're testing for continuity, where are you testing specifically? Your next step might be to check and make sure you have a good connection at the harness(es). If that checks out, depending on how the seat cushion and back are wired, it's possible that one of the wires has become abraded, breaking the circuit to both elements. Check for visible breaks in the wiring between elements. If no wires appear damaged, then I would probably strip the seats and inspect for a break in the element itself. You may very well be correct about it being the element (didn't mean to suggest otherwise). No way of knowing until you dig in, I guess!
