As far as the windows go.
It sounds like your motor is going/gone bad, the lucky thing is that they're not too terribly expensive to replace and honestly aftermarket motors are much better than the stock.
The easiest way to tell is if you take the door pannel off and knock on the motor with a hammer (like you would a starter) if it works then the motor is bad. If it was a short then it would usually shut off your radio, or interior lights (they're routed through the same wiring.)
is where I got my Motors.
One thing that I have to warn you about is that alot of the time with replacing the motors, you'll most likely have to make some adjustments, because the motor will either push the window up too far or not enough (pain in the @ss.) :bash:
As far as the locks go, Im really not sure, if they're making noise, then it's possible (likely) that the motor/actuators are going bad you can find these on eBay, or in a junk yard cheap.
Hope this helps...
