Default power window switches do not work properly

Usually the driver side has all 4 windows switch can control all the windows up and down.
And to lower the window, push the switch halfway down, or push to switch all the way down to fully lower the windows(the window comes down automatically).

But after replace my battery,window switches do not work properly.
The driver side switches can not control other 3 windows, And push the switch fully down. the window won't comes down automatically

What is the problems?
Thank you

After you install a new battery you will have to reset the windows, moonroof and the deck lid (maybe), It is explained in your owners manual.

Told you on your other thread that you needed to read the manual about how to reset the window controls after changing out the battery:

Afterwards, check your Owner's Manual about how to reset your window controls.

Those headlights draw a lot more power than the radio does -- 55W @ 12V (each) if I remember correct. Probably why you had no problems with just the radio on.

You will also need to reset your sunroof. Depress and hold the tilt button until the roof tilts up, tilts closed, slides open and slides closed. Then i/release the button and t will be reset. If your rear hatch doesn't seem to operate correctly just open and close it manually to reset it.

From the Owner's Manual page 694:

If the battery is disconnected or run down

The following functions may not operate correctly when you
reconnect or replace the battery. In these cases, you should
do the each instructions referring on the following pages.
 Power back door (See page 46.)
 Power windows (See page 74.)
 Moon roof (See page 148 or 152.)
