How do you replace door handles on a 1989 XJ6 Jaguar?

This is not a job for the faint hearted. You will need a lot of patience and dextrous fingers. Remove the interior door panels...look into the handle area and spot the 3 small nuts that hold the handles to the door skin..remove and save... locate operating rod clips, release, ease handle out from door, locate loom connectors for lock barrel heater and lock control, they are secured from being trapped by the window in a small clip...... disconnect and remove handle.

Reassembly is reverse of removal plus a little more fiddling about !.
