BUMP... I'm having the same problem. My passenger door window gets stuck when lowered. It doesn't respond using both the passenger doors switch OR the drivers master control keys.

Thank you "Golden" I just did the step-by-step and it took me 1 hr. The truck started right up and is running beautifully. One thing though, once I started the truck, the TRACTION OFF light came on along with the VCS and the CHECK ENGINE LIGHT. Did this happen to anyone else?

My Rx300 has exact same problem, so I got read the forum and took out the 2 air intake hoses and the IACV locates right under them. I took out the two screws and cleaned the inside with the throttle body cleaner. The problem went away, so here is the pictures I took (IACV is the black piece with the two screws, one of them has the yellow dot on it).

Hope this help somebody in the future.

Thanks for help. My 01 RX300 had trouble with idle and low rpm idle too. Cleaned the idle control valve as instructed and works great. A little note for first timers, use a #3 philips screw driver for the 3 screws on the throttle body. Be prepared for coolant to leak out, I had about a quart of coolant leak from the hose line. Maybe it was because the car engine had been run. I did have to buy 3 new screws from the dealer, as mine were a worn out.

Ok so I followed the instruction posted by 'oldrx300' and the problem is still here. Now I noticed in the picture that 'RX300BILLY' posted he took apart the whole assembly not just the IACV. Is this what I'm supposed to do? Any help will be greatly appreciated. Thank you.

Hi everyone, just wanted to say hi. Found this site and I'm very thankful I did. You guys have helped me a lot when it comes ot my '01 RX300. Thanks once again...
