Detailed Description

Standard Ignition DS-1440 is an OE-style door window switch for the left door on select Chevrolet Express and GMC Savana vans, as well as 1996 Chevrolet G30 and GMC G3500 applications. It is built with copper alloy conductors to support consistent current flow and is tested to verify both switch action and electrical function. This part cross-references Dorman OE Solutions 901-051 for the same application. Standard Ignition DS-1440 is a direct-fit choice for technicians servicing power window switch failures on Chevrolet Express 1500, Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 1500, GMC Savana 2500, and GMC Savana 3500 models.

Common Problems It Can Solve

• Inoperative driver-side or left-side power window control

• Loss of response from a cracked or failing switch assembly
• Poor conductivity from aged or corroded switch components

Installation Notes and Tips

Verify the connector style, terminal count, and left-side placement before installation. Confirm the vehicle application by year, make, and model, especially on Chevrolet Express and GMC Savana vans. Inspect the harness connector and terminals for heat damage or corrosion before connecting the replacement switch.
