The RX 330 is a luxury crossover vehicle made by Lexus. Its rounded rear window design makes a rear wiper necessary to keep the window clear while driving in stormy weather. Rear wiper blades should be replaced annually for safe driving.
Lift the arm away from the rear window. Pull the arm straight back from the window until it clicks to disengage it from the wiping mechanism while you replace the blade.
Locate the lock on the bottom of the wiper housing and push down on it to unlock the rubber blade from the housing. The lock on the RX 330 is a small plastic tab with a downward-pointing arrow near the very end of the wiper.
Pull down firmly on the old blade to remove it from the housing. Remove the two small metal tension strips from the old blade and fit one on each side of the new blade.
Slide the new blade back inside the housing, guiding it into the slot with your fingers. Push the tension strips down so they are centered between the blade and the housing. Snap the locking tab closed.
Push the wiper blade arm gently down against the window. Turn the rear wiper on low to make sure the new blade is functioning properly.
