Unless it is positioned wrongly, normally the only time you have to
remove them is if you are replacing the motor (or possibly getting
access to something behind it). I'd always change blades "on the car".

I've replaced a couple over the years - both times because the spring
has weakened and so there has been a lack of pressure of the blade on
the screen.

Fair point; I think I replaced one many years ago (fatigue crack in
spring hook).
