Built for Rear Lighting Repair

Dorman 923-017 is built to restore tail light function on 1996-1999 Chevrolet Express and GMC Savana vans when the original rear harness is damaged, corroded, or no longer making a reliable connection. The harness uses 16-gauge wire, tin-plated brass terminals, and integrated grommets to support a clean replacement at the rear lamp area. This part cross-references OE numbers 1P2075 and 16521949 for the same application.

Common Problems This Harness Can Address

• Intermittent or inoperative tail lights
• Broken, brittle, or heat-damaged rear wiring
• Corrosion at the tail lamp connector

• Water intrusion at the harness pass-through area

Installation Notes and Tips

Verify the vehicle’s rear lamp configuration before installation, especially on 1996-1999 Chevrolet Express 1500, Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 1500, GMC Savana 2500, and GMC Savana 3500 models. Match the connector style, terminal layout, and position to the original harness before connecting. Inspect the lamp sockets, grounds, and surrounding wiring for additional damage so the repair is completed at the source.
