Rear Door Window Switch for 1997-2005 Buick Century & More - Standard Ignition DWS-126

Control the rear power window with a fresh switch built for GM vehicles. The Standard Ignition Door Window Switch / Power Window Switch DWS-126 is a direct-fit rear-position replacement for the 1997-2005 Buick Century and 1997-2004 Buick Regal. This part is listed under both names, door window switch and power window switch.

Mounted in the rear door, this switch is what a rear-seat passenger presses to send power to the window motor to raise or lower the glass. Standard Ignition engineered it as an OE replacement with copper alloy conductors and switching performance that is verified by testing.

• Copper alloy conductors: carry current with strong electrical conductivity and low resistive losses.
• OE replacement design: precisely engineered as an OE replacement for a seamless fit, proper performance and simplified installation.
• Tested switching: undergoes testing that verifies both mechanical and electrical switching performance for reliability.
• Made for GM: specifically designed for GM vehicles and a preferred choice of professional technicians.

Signs this switch may need replacing include a rear window that won't respond to its switch, one that works only intermittently, or one that moves in one direction only. A window motor, regulator or wiring fault can cause similar symptoms, so diagnose the cause before replacing the switch. See the "Vehicles it fits" section for complete application details.
