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.

I hope this helps. Let me know if you have other questions.

Take care and God Bless,

We need to check the seat circuit breaker fuse in the IP relay block because it runs both seats. Then we need to check power to the motors from the switch.

I attached the wiring diagram for both seats but I suspect the fuse is the issue.
