How to Change the Rear Wiper Blade on a Lexus RX 330

Water on the window after a wiper has passed indicates the need for replacement.

Windshield wipers blades function properly only for a certain amount of time. Once a blade stops clearing water from a window or leaves streaks, it is time to replace that blade. Change the rear windshield blade on a Lexus RX330 by purchasing a new blade, removing the old, nonfunctional unit, and inserting the new blade in its place. Changing a wiper blade, once acclimated with the wiper arm and unit, takes most people only a few minutes.

Instructions

Changing Rear Wiper Blade on Lexus RS 330

1. Purchase a replacement blade from an auto parts dealer or mass retailer. Consult owners manual for size of blade and product specifications. Double check purchase with in store wiper blade guide and store employee.

2. Remove the old blade. Stand the wiper arm up by pulling the entire apparatus away from the car. Push down the small plastic lock near the end of the wiper blade to loosen the rubber blade and pull firmly to slide it from the arm.

3. Attach the metal strips from the old blade to each side of the new blade. Slide the new blade back into the arm, making sure to guide it between all sets of double pronged holders. Engage the locking mechanism when the blade fits entirely into the arm.

4. 

   Double check installation by activating the wiper from inside the vehicle.

   Replace the arm against the rear window and check the blade movement by turning on the rear wiper. Make sure to check that the wiper moves smoothly before operating the vehicle in inclement weather.
