    Next time the window does not work, try slamming the door while holding the button. If that works, then the motor is probably going bad.

    Pull the DTC's per the sticky at the top of the page to find out why the SES light came on. Be sure that when you put the gas cap on you keep turning till it ratchets a few times. You probably have an EVAP code. A loose gas cap is the most common cause, that is why an EVAP code will always trip that message.
