If the door latch has broken you will have to fit a new latch. Part No. 791205 from F&P Door switch assembly.
Fitting involves removing the screws on inside of door and remove the outer door panel. Then remove the top panel and replace the switch assembly. Put top panel back on and then outer door panel.
