how do I fix my drivers side window that is off track?

Well, either the window has fallen off the track and just needs to be placed back on the or the power window motor is done. Either way you are going to have to remove the door panel, there are screws located all around the door, just remove the screws and door panel should pop off. You should be able to tell if its the motor or the track without doing so though. When you hit the switch to put the window up do you hear anything or does anything move at all inside the door?

yes the thing inside goes up and down.

I hear a clicking sound.
