I recently purchased a 2001 zafira to get all the sprogs in. I bought it knowing the rear drivers side door would'nt open, hoping it was a quick fix of putting a rod back on or something, managed to get the door card off

and everything thing seems to be connected and trying to open ,it just wont ! iam a bit stumped as to how can you change the module thingys on the inside of the door if you cant get the bleeding thing open?
please help before i go insane, is there anyway of over riding , removing with the door shut
cheers
