Maybe I'm just an idiot, but I can't figure out where the main switch for the power windows on my 07 XLS is located. Page 3-64 of the manual says it's located on the driver's door and can operate all windows at once, but I don't see it. The driver's window switch doesn't do anything to the other windows. Is this an optional feature that I don't have? Feel free to laugh at my stupidity if I'm missing something obvious. Thanks!

 

Yeah, what Im getting from this, is that your looking for the main window switch. There is no-one button that will make them all roll down at the same time. There is a button directly in front of the drivers side window button, (the one that works the drivers window) and that button locks the other windows, It wont lock the drivers window, but it will lock all the otheres, and from what you are saying, thats the best that I can come up with for an answer.
Oh btw, you just press it (put it in the down position) to lock, and depress it (push it again, and it will pop up higher) to unlock them.

 

The main switch the manual mentions is the whole switch panel itself composed of 5 switches and does not refer to a single switch. In other words what it says is that from the main switch panel, you can operate all 4 windows using the 4 different individual switches in the panel. I don't think that there is a main switch to operate all windows simultaneously.
