Standard Ignition S2508 left switch for the 2003-2006 Chevrolet Silverado 1500 and other vehicles is a multi-function connector for door lock and power window switch wiring. This Standard Ignition switch connector replaces a damaged plug on the door lock or power window switch.
A door lock or power window that works only some of the time can mean this connector is worn, though the switch itself or the window motor can be behind it too, so find the actual cause before replacing the connector.
The listing covers a wide range of Chevrolet, GMC and Cadillac models, including the 2003-2007 Chevrolet Silverado 2500 and the 2003-2006 GMC Sierra 1500. To check your exact model and engine, open the "Vehicles it fits" section. The 2003-2006 Chevrolet Silverado 1500 takes one on the left side; the other side is a separate part.
