First the driver side went out then about two weeks later the passenger side went out.

Did you check to see if the switches still work?

some times you have a lose wire in there.mine did when l took it to a mech.,he put it back in place now l have one window that will roll up.lol on me

the most common cause for this is the switches fail and you get no contact. often you can get switches from parts plus, autozone etc no dealer needed. the question is do you hear anything when you push the switches because the dealers use some crappy cable systems that like to break.
