Dorman - OE Solutions Window Regulator P/N:740-577
Replace a worn or broken lift mechanism with the Dorman window regulator 740-324, a power window regulator built to raise and lower the door glass at the front left position. It fits many vehicles, among them the 2007-2009 Lexus RX350, 2006-2008 Lexus RX400H and 2004-2006 Lexus RX330. See the Buyer's Guide tab for the full list.
This Dorman OE Solutions window regulator is sold as the regulator only. The power window motor is not included.
If a failed regulator is behind a window that moves slowly, sits crooked, grinds or clicks, or drops into the door, this unit replaces it. A failing motor or switch can cause similar symptoms, so diagnose the cause before replacing parts.

Does this include the window motor?
No. Dorman lists 740-324 as a power window regulator sold as the regulator only, so the window motor is not included.
