Hi,
If both failed at the same time, I suspect it is a bad circuit breaker in the instrument panel relay box. If you look at pics 1 and 2, I included the entire wiring schematic for the driver's side. I highlighted the circuit breaker. Also, I highlighted an orange wire that will be at the switch on the seat. Check that wire for power. Pics 3 and 4 are of the passenger's seat. It is basically the same, just a different seat. Do the same there.
Here is a link to help with confirming power is in the relay/fuse box:

Here is a link that explains how to test wiring. This will help when you check the orange wires at the switch for power.

Pic 5 shows the location of the circuit breaker in the box.
