So you have to calibrate/reset that.

It's not needed on 09+ models as those have flash memory (seriously) in each window controller to remember the position even after loss of power.

My 2003 non lexus car with power windows did not have a problem like that. What gives? Is lexus behind the curve?

Other way around- your 2003 non-lexus had more primitive power windows that worked less precisely (and thus didn't know, or care, where the window was in its travel).

and so how does it help? the older technology also worked great...never broke down. Just trying to nail down the exact reason behind this logic.

IIRC the window will actually go faster when it has further to go to get to all the way open or closed, versus when it's nearly there.

(I wanna say there's also a safety element of it knowing when it's meeting resistance but has NOT traveled far enough to be closed all the way but I might be imagining that part)

Did your old windows have an auto-up function? The need to re-calibrate after disconnecting the battery is fairly common on power windows with an auto-up function; not just Lexus/Toyota/Scion.

You actually only need to roll the windows down ever so slightly (not even halfway, 1 cm will do) then roll it back up and hold it for about 1 second until you hear a clicking sound. This can save you a good 10 seconds.

I have disconnected my battery, and I tried resetting the windows. But the passenger windows would not even move at all, so how do I reset them? The Auto-Roll on the driver window is fine though.

By the way, mine is a right-hand-drive model if it matters.

Default How can I do the fix if windows don't move

I had the battery changed and my driver window is stuck in the down position. I am trying to do the fix in the other posts by rolling all windows down halfway and then back up (holding for a second). I cannot do this because my window does not move at all.

What am I missing because I am sure it is something simple.

This is the same question I have but I did not see a response. Please help because it is going to snow here and my windows are stuck down.

here is what to do in simple terms:

1. open driver side front window halfway
2. close driver side front window and hold switch for 1 second
3. have a look at the other door window switches (they should be flashing)
4. repeat same procedure with other 3 window switches


Easy enough

I looked at the threads but my drivers side window does not move and that is step 1. If I cannot do step one then how do I do the other steps?

Such a simple fix! Thanks for the help. I have a 2004 GX470 and had disconnected the battery.
