Are you just telling us this, or were you wanting some help with getting them to work?
If you want help, you need to give us some more information.
What year is your LS? There are some differences in the way the windows are wired between the two different generations of the LS.
Do all of the windows work from the driver's door, but not from their local switches? Are you certain that this includes the front passenger door? Are you certain that you have the window lock switch off? If you put the key in the driver's door and turn it to unlock and hold it there for a few seconds, do all the windows open? If you turn it to lock and hold it there, do the windows all close?
Do you mean that only the driver's door locks and unlocks when using the lock switch inside? Or, do you mean that the lock switch on the passenger door doesn't work. Do the locks work when you use the remote? Have you pressed unlock twice on the remote within a second or so?
Did everything that isn't working stop working all at once, or have different things stopped working over time?
