Performed IS250 Spark plug change.
 

It was a success! But now Driver window panel does not work for any other windows. I only could control my window side. Has this happened to anyone else? Please help me trouble shoot! Yes I removed the battery when I performed this.

You can find this in the sticky section but here you go

Gonna go off memory here...you have to reprogram your window. Press start button but don't turn engine on.

Roll drivers window half way down (not with automatic lower) but with your finger controling power...roll back up and hold for 3 seconds

Reach over to passenger window..this time roll all the way down...then back up....keep holding button up for 3-5 secs...

Repeat with other two windows..

You have to use each window switch from the door its on...then youre set

What causes it to lose memory on the windows?

thanks everyone ! I appreciate it !

OP said they "removed" or disconnected the battery when doing this DIY project. Since the battery feeds all of the various ECUs in the car their power when off, the memory of the auto-down/auto-up function is lost every time you disconnect the battery from the car..
