2005 Vauxhall zafira b boot lock will not open, fuses & wiper/washer ok?

Help. I've replaced the lock so nor solenoid related bit boot will not open from handle, it will from inside the car though. When using the central locking I hear nothing from the lock but I do hear clicking from the fuse box in the boot. I've check fuses and all ok, even removed and replaced everything in the boot fuse box. At a loss now :-(
