Is this covered under warranty? My drivers side window barely moves, will the dealer replace the motor?

Yes it's covered under warranty. It's a known issue and both my windows were 'fixed' once so far and they now run slow again. Hopefuly the next time i have them fix it, they will actually replace the motors. I guess it varies greatly from dealer to dealer. Good luck!

They should (if < 36K), but in case you are past 36K:
There seems to be a lot of talk about bad window motors. Auto Zone has a life time motor.

from http://csce.uark.edu/~jgbertr/rb/alt_web_page/windowmotor.html
"The most reported symptom of the window motor dying is that the motor will stop when attempting to raise the window. After a minute or less and you try it again, it will go up some more and stop. The cycle repeats until you can get the window fully up. Usually the longer you wait between tries, the farther it will go up at a time. The motor has an internal electronic circuit breaker (thermal resistor) that will heat up and trip when the motor is overloaded (either by just being worn out or from trying to overcome mechanical drag). This causes it to have to "rest" before it will go up some more.

It is also a good idea to check that your switch connections are tight because that can add resistance to the circuit. Switches can fail too and are not that expensive at wholesale price from the dealer (~ $13 for the driver's side which includes both switches in one housing, less for the single passenger side). A common source of failure of the switch is not even electrical. The plastic switch button shell (the part you press on) will crack on the side and not allow the actual switch underneath to be depressed far enough to work. If the window will operate ok if you press really hard on the button, try replacing the switch.

For anyone who has ever owned a 4th gen (1993-2002) F-body, whether it was a V6, V8, Pontiac, or Chevy, if you had power windows, more than likely, you had a motor go out on you, or at least had very slow moving ones. As much as I love my car, there are some definite weak spots about the car, and the power windows are one of them.
Part of it has to do with the motor that GM uses, but the biggest problem is the humungous windows that are in the F-bodies. You may not realize it, but those windows are very big by car window standards and weigh around 40 lbs each. That motor has to push that thing up and down each time you push your button.
