Vauxhall Zafira central locking

Locked my car car with key fob as normal while out shopping, got back to car & unlocked car with key fob, only to find no doors would open except the tailgate. I know the tailgate is separate to the doors as its on the same fuse as the water jet for the screen. I had to use the key to open the driver door to get home. Once home started to look into the problem, while pressing the key fob I could hear all locks working in the doors, but no doors would open, so knew it was not a fuse problem. Looking on the net found out a common problem was broken wire in the wire looms between b post & rear doors. So checked all wire looms & found broken wires in both rear door looms. So repaired them & got driver door to open & osr & nsf door open.....but nsr door will still not open. Has anyone had same problem? Any help would be great as have mot fast approaching & I know they won't mot car if door won't open!!
