Replacing the wiper blade, rear window
Lift the wiper arm from the windscreen and pull the upper section of the blade diagonally down to the right.
Grip the centre of the wiper arm and lift it from the windscreen to lock position.
There is a lock position at half extension angle that may feel like resistance. This lock prevents the arm from falling back against the windscreen. The wiper arm must be pulled past the lock for wiper blade replacement.
Grip just above the blade's centre bracket and pull diagonally down to the right until the blade loosens from the arm.
Lift the cover for the wiper arm's bracket. Be careful that the wiper arm does not mistakenly fall down to the windscreen again.
Loosen the washer hose from the bracket.
Attach the new washer hose with associated wiper blade into the bracket. Fold down the cover for the wiper arm's bracket.
Make sure that the hose is routed in the same way as in the illustration. Otherwise it risks being pinched by the casing when it is lowered again.
Press the new wiper blade into place. You should hear a click. Check that it is firmly installed.
Lower the wiper arm.
Check the blades regularly. Neglected maintenance shortens the service life of the wiper blades.
