My 2008 RX400h has a problem where the power window switches on the driver arm rest will not operate the 3 other windows. It will operate the driver side window. The windows do operate at their respective local switch.

Could this just be a fuse, or does it sound like the switch itself is bad or some other electrical issue ? If a fuse, can someone tell me which fuse, or how I would isolate that ? I found a fuse diagram online, but I don’t see any mention of the power windows on it.

(The Lock Window switch is NOT the culprit - it has no affect.)

Thank you.

It sounds like you had the 12V disconnected recently. I can't remember off the top of my head, but there's a simple way to reset the master window control. I believe you have to lower the window at each door, then hold the window switch in the "up" position for a few seconds after the window is fully up. You have to reset it every time the battery is disconnected. You should also reset the ISC too.
