1. Before removing the leash, turn the wiper on and off to make sure the leashes are in the normal parked position (wipers are parallel to the bottom edge of the windshield).
2. Lift the flip cap at the lower end of the driver and unscrew the lock nut. Raise the driver to the end in order to release it from the latch, and remove the driver from the drive roller (see photo).
3. The leash is installed in the reverse order. When finished, check that the blades are parallel to the bottom edge of the windshield and check the operation of the wiper (after wetting the glass so as not to damage the brushes).
