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.

 

Like many questions you might have, this one has been discussed on numerous occasions here at CL. No need for a new thread as it can easily be searched. For example:
