Shop Buick LaCrosse Replacement Window Regulator

Power windows require a top operating LaCrosse Buick window regulator to make sure your windows are able to move. Held within the vehicle doors, the LaCrosse Buick window regulator employs gears and a pulley to open and close the window as well as put windows at a desired position. Once someone applies a toggle switch, the window motor rolls into action. The motor powers the regulator.

Once the toggle, or relay switch, is turned on, the LaCrosse Buick window regulator uses worm reduction gears to reduce the 12-volt power by four volt increments to adjust the windows. While the part is built tough, it can short out or gears and the pulley can fail. When that happens, the power windows won't work. That means the window regulator has to be replaced with a quality component fitting the mid-size luxury sedan introduced in 2005, so the power windows can be operated as designed.
