Can someone help me identify/locate the trunk release relay (03 Vectra C saloon). My guess is it is in the fuse box in next to the battery as that's where the fuses are located.

The problem I'm trying to solve is that the electric trunk release does not work -- even manually pressing the release does not operate it (neither does the switch on the drivers door nor the switch on the key fob.

On disassembling the lock, I probed the power supply while pressing the remote switch. The fob switch caused the lights to flash while pressing hte trunk release, but there was no power being fed.

I'm hoping it is a malfunctioning relay.

My Haynes manual has not arrived yet. So, any help (pics specially) would be appreciated.
