Under the cap. Pop it out. It is just a snap on. Just use a screw driver with a tape to protect the cap from being damaged.

 

Mandyfig. I cleaned the blades on RX300 for a couple of years. And Ive had my RX350 for a little over a year. No problems with them becoming brittle or tearing.

 

Great deal. I will try the alcohol cleaning technique. My Camry needs it bad.

 

look on the Trico website to find out where Trico Wiper blades are sold and get a 14-A, pop off the cover (as described in other posts), take off the old wiper put on the new one, it is an exact copy of the old one, I kept reading where others had difficulty finding a blade, this was $10 and an exact match.

 

For the rear wiper on my RX330, you get the base plastic cap off by just pulling out and up on the sides. It will "pop" loose. Don't worry... it's not broke. Once that base cap is off, you are able to flip the wiper arm out 90 degrees to work on it. Then simply "pop" the base cap back on when you are done.

 

I thought that Alcohol is not recommended for rubber because it dries it out. I was told a mixture of water and vinegar is good for cleaning rubber.

 

I wouldn't use alcohol. Instead, just use soap and water to clean.

 

I use that 303 aerospace stuff. It really preserves the rubber.

 

Replace the rear every 2 years be done.
