Good morning,

You need a test light or voltmeter to verify power to the relay under the driver's seat as indicated in the wiring diagram. It is possible that you either do not have power to the relay or that the relay may be the issue.

Check the fuses listed again for power on both sides with the key on.

Do you know where the relay would be for the power trunk release?

It is an actuator, not a relay.

I attached a picture for you. It is at the trunk lock itself. A signal is sent from the switch to the actuator to open.

Is there anything under the seat at all? Any type of module?
