The relay plate is, as expected, under the banks of relays and that looks fine.
However, the only relay in the upper bank is marked EA4 D113-01 382 and this is variously described as Rear lamp tester relay or, on Ebay, interior light relay. I suspect that this relay is not working as the resistance across the terminals is 3M ohms.
Does anyone have a wiring diagram for the relays as these are absent in the Haynes manual?
