I read some back threads which saved me a fortune. I made the mistake of going to a mechanic to replace my battery in my RX 330. After it was changed out my power windows stopped working. He actually told me it was the luck of the draw and he would have to replace the master window mechanism. My answer was no. The part was $700 plus labor! So, I've been driving around a couple of days without my windows working and googled this site. There it was, the answer. I can't thank you all enough. I just went to each door and opened each window halfway. Then I closed each one and held the button in the up position for a couple of seconds. Reset! Everything works now. Thank you so much!
