My X type frozen door

G’day all,
Really frustrated here as I have been trying for 2 days to get the rear right door of my 2004 x type open without any luck at all…
It appears that the actuator for that door has jammed or seized and I have used a can of WD 40 to try and free it but to no avail…
I have also fully charged the battery and tried to put direct current to the lock , still no luck…
I have removed the door card and checked the internal cable and external locking bar and they seem fine and where they should be …
I have banged , kicked , cursed and cussed and have even drawn blood trying to force the door open … And here I am now
Please, please PLEASE , somebody have a solution other than a match and a can of petrol…
As I believe this is not an unusual problem…
FORD certainly have a lot to answer for :wink:
Thanks in advance
