Welcome to AF.
First check your fuses.
The check the switch,
you can pull the window button panel off.
At the top of the button switch is a small place where you can lift/pry it up with a straight slot screwdrivr.
I'd try checking it for power and maybe clean it up if thiers debrie in it. Sometimes stuff gets in there and you can blow it out or just work the button rapidly to free anything under the contact switch.
this might help, has some pics that relate to your alero,
about 5 paragraphs down, "Door buttons".
Then another 4-5 paragraphs dwon is another pic of the "button switch".

Hope that helps.
