Great write up worked absolutely perfectly. Thank you. Door now back in operation.
Took the handle carrier out for a quick check and lub job, just in case, having had to replace the one of the drivers side a while back.
One point, it may be worth placing a small block of wood in the door jamb, to prevent you inadvertently knocking the door closed whilst manoeuvring around it, like what I did. Both handles were disconnected at the time!!!!!
