Drivers side power window is stuck down. What can I do ??

SOURCE: 2002 Buick Lesabre drivers side window went down,

A couple of things to add to tinyp's solution. For Buicks, the regulator is bolted in, not riveted, which makes removal easier. Also, you'd better get used to this, as I have replaced 3 out of 4 window regulators on my 2002 LeSabre.

If neither switch works it is a bad connection at the motor or bad ground or a bad motor. Remove the door panel unplug the motor push the switch and see if there is 12volts on the wires if there is the motor is bad There are small brushes in the motor that go bad tap on the motor while pushing the switch if it works that way replace it

There should be a couple of screws on the arm rest that you need to remove and probably one on the door handle then you need to find something to pry the panel off with, without breaking the plastic clips. They make a special tool for this that you can buy for just a few dollars at any auto parts store. If attempting to do it without the right tool be careful not to break the clips.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door
