Default rear lift gate has no power

rear lift gate has no power. the wipers will not work, the defog will not work, it will not lock nor the glass make any attempt to lock.
checked fuses and everything is okay. there is power all the way to the wire harness into the gate.
somebody told me that there is an electronic board in the door that also handles the keyless entry.

tell me what else to check
