How do i put driver side window back on track on a 91 acura legend?

Well, after removing the door panel and disconnecting all of the necessary parts(please be careful in doing this, some of the parts will break quite easily), look toward the inside front of the door (near the hinged area) - there's a track located there that extends all the way up to the top of the door and this is probably the reason your window keeps coming off track( this was the case with mine) - There's a bolt that holds the track in place. Loosen it a little to get the window back into the track. Put the window back into the track but make sure that the rubber guide on the upper and lower part of the door remains around the windows edge, re-tighten the bolt and then reconnect the window controls to test it. It should flow up and down as if new. .
