Put driver-side window control back at your fingertips with the Standard Ignition Door Window Switch DWS-303. This front-left (driver's door) power window switch drops in as a direct-fit replacement for the 2007-2010 Saturn Outlook — see the Buyer's Guide tab for engine-level fitment details. When the switch that raises and lowers the front-left glass stops responding, sticks, or works only intermittently, replacing it restores control of the affected window.
- Copper alloy conductors: deliver strong electrical conductivity with low resistive losses.
- OE-replacement design: precisely engineered for a seamless fit, optimal performance, and simplified installation.
- Built for GM applications: specifically designed for GM vehicles and a preferred choice of professional technicians.
- Verified switching: undergoes testing that checks both mechanical and electrical switching performance for reliability.
Signs the original switch may need replacing include a window that won't move from that switch, erratic operation, or a button that must be held at an angle to respond. Diagnose the cause before ordering, since motors, regulators, and wiring can produce similar symptoms.
