How to change the rear wiper on your 2006 Lexus Rx400h
Release the old blade
Lift the wiper arm off the window. On some vehicles, you may have to remove the cover where the wiper arm is attached to the rear window. Grasp the wiper arm with one hand and rotate the blade directly toward you.
Remove the wiper
Once rotated, the wiper will release from the wiper arm with a gentle click. You can now take it off the arm.
Position the new blade
Place the small bar attachment on the new wiper blade into the hook on the wiper arm.
Lock the blade into place
Rotate the blade away from you and it will snap into place.
If you removed the cover from the base of the wiper arm, put it back into place. You’re done!
