Not uncommon to have faults with tailgate wiring:~
Not just Volvo- the continued flexing of the above can break or lead to frayed wire, sounds like you have this problem.
The loom can be repaired by splicing in new wire, the hinged area is generally the culprit.
If you do a search you should find further advice- cable connections are under the rear headlining so the wires can be worked out for the repair without total removal, shrink sleeves will also reinforce the loom.
It gets a bit long winded accessing the fault/hinge removal but a straight forward DIY repair (Do one side at a time- no need to purchase a new loom- colour coded wire is fine allowing extra length for a fresh location .
As time is now a little short approaching MOT day etc I would disconnect/remove the 3rd light until you can do a full repair.
Its likely that other wires are on the way out?
Good Luck.
Bob.
