Our RX 350 the power windows are coming down on their own. The first time we noticed it in the garage when we came out in the mornig absolutley every window and the sun roof had been opened. My wife just told me today the 2 front windows were half way down when she came out of the store today...whats up this ??

Fuse is blown. Replace fuse for the said windows.

Did you change or unhook the battery? If so, the power windows can be reset. I believe this is in the manual as well.

reset passenger window by running it down all the way. then run it up and continue to hold the switch up for ~3 seconds after the window is all the way up. that should reset it so it works from the driver's side controls.

I was able to reset the rear windows the same way (I did flip the child lock on the door as well).

Looks like the window/door control ECU lost it's program while the power was off or low. You need to see the lexus dealer to reprogram the ECU which is done with a sequence of buttons to press.
