Front door lock problems


A2OC Donor
Pax side front door lock will not desafe so decided to remove the lock to resolder the micro switches. Can it be done without disturbing the window runners?
Door card and aluminimum plate removed (how many bolts? far too many!) Got the two splined bolts from the lock but whilst disconnecting the exterior door handle from the lock the small plastic connecting piece broke. I suspect I am now screwed and the lock is loose but still in situ.
Any pointers?
