You are correct in your assumption about a relay... there are two relays. One is for 'LOCKING' the other is for 'UN-LOCKING.' They are both labeled as "LOCK" relays (1 & 2). You can verify if a relay is bad by swapping one with the other. If the problem moves to 'unlocking' the doors, but will NOW LOCK - the relay is bad. If not, further troubleshooting is necessary.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. You can then pull off the weather seal and access the insides of the door. The actuator will be held down by two bolts that may be tricky to access
