I've done this a few times before, but short of removing the arms or bonnet I cannot remember how to do this easily! what am I missing, please
This may work on a late model, CANBUS, 406.I don't know if a 406 is the same as my 407 but to change my ones I switch the ignition off after the car is running and then just after touch the wiper stalk . The wipers will then park in the vertical position . I can then swing them forward to allow the blade change . Once you are done put them back on the screen start the car and touch the wiper stalk again and the blades will then park in the normal position . Hope this helps
