You also need to see if there is a live feed from the dash switch in both directions, press the switch down and one wire will become live, press it up and another wire will become live. These wires switch the main lives in the relay, from the relay you have a thick red wire and a thick black, these reverse live and negative to power the motor in one direction (up) and then in the opposite direction (down).
If you already have the main battery (ignition) live, thick red into relay and lives from the switch in up and down directions and the connections under each side trim panels are plugged in then I think you relay isn't switching and not feeding to motor. If you have bridged the thick red wires and the motor powered up then the motor is fine, try bridging the thick red in and the thick black out to see if the hood moves back.
Keep going, your getting there
