Both mirrors are now free and moving.
I used the electrics to move the mirror over to one side and sprayed WD40 inside the casing. I then used the red tube which comes with the can and forced it into the gap between the mirror housing and the base that fixes to the door. I worked out where the spring was by using the photo supplied by Mazza and gave it a good soaking in WD40. Within a few minutes it was free and working. Result!!
