Dorman - OE Solutions Window Regulator P/N:740-324
$46.99

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.

  • Engineered to the original: Dorman engineered and tested it to replicate the original window regulator's fit, function and performance on the listed applications.
  • Cycle-tested: Dorman tested it by running it through thousands of cycles in an actual vehicle door.
  • Direct-fit shape: Reverse-engineered to the original equipment shape and dimensions for a direct fit.
  • Engineered in the USA: Engineered in the USA and backed by Dorman's long history in the automotive aftermarket.

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.

What does a window regulator do?

The regulator is the mechanism inside the door that guides the glass and moves it up and down when the power window motor drives it.

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.

What are signs a window regulator may need replacing?

Common signs are glass that moves slowly or crooked, grinding or clicking inside the door, or a window that drops. A bad motor or switch can cause similar symptoms, so diagnose the cause first.
