Standard Ignition DS-871 Door Jamb Switch - Front Left, Front Right or Rear

Door Jamb Switch for GM Applications

Standard Ignition DS-871 is a direct-mount door jamb switch built for reliable electrical switching at the door opening. It uses a black plastic finish, a female connector, and two male blade terminals to support clean replacement on a range of GM vehicles, including Chevrolet Blazer, Cavalier, S10, Express vans, GMC Jimmy, Sonoma, Savana, and related models.

For drivers dealing with courtesy light, dome light, or door-ajar signal concerns, this DS-871 switch provides a straightforward OE-style service part for rear and front door locations where listed.

Detailed Product Overview

Built with robust materials and copper alloy conductors, the DS-871 is engineered to maintain consistent switching performance in daily service. Standard Ignition focuses on technician-friendly replacement parts, and this switch reflects that approach with a simple direct-fit design for the door jamb location. It is a practical replacement for GM door-activated circuits on vehicles such as Chevrolet Blazer, GMC Jimmy, and Pontiac Sunfire, as well as Express and Savana vans where the fitment calls for front left, front right, or rear placement.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
