If it is a multi-layer board, I wouldn't remove it unless you have experience with these kind of repairs.

In fact, that may be the problem, if he replaced the relay and there are traces on the component side of the board that were damaged.

Follow the traces to the relay, and see if they all conduct to the corresponding relay terminals, from the other components.

Try to get a schematic of the board from the manufacturer, and we'll be able to diagnose.

Edit: looking back at the pics, I can see traces through the board that look like they go to the relays. See if they conduct and confirm that they should go to the relay. If they do not conduct, rather than disturb the parts, add a jumper wire. When he removed the relay, he may have disturbed the plated through holes.
