Detailed Product Overview

This Dorman door check is engineered for vehicles that need a direct replacement for the original front left door check assembly. It helps restore controlled door movement on applications such as the 2002-2004 Chevrolet Trailblazer, 2002-2004 GMC Envoy, and 2004 Buick Rainier, while also covering 2005 models including the Chevrolet Trailblazer EXT, GMC Envoy XL, GMC Envoy XUV, and Saab 9-7x. The part number 924-157 is also a useful reference when verifying the correct replacement for the OE-style application.

With a length of 4.14 inches and width of 1.39 inches, this door check is designed for specific fitment and uses a 3-hole mounting layout. The steel, rubber, and nylon construction supports consistent door stop and detent action, helping the door open and close with controlled resistance. This part cross-references OE number 15196109 for the same application.

What This Door Check Helps Address

• Loose or uncontrolled front left door movement
• Door overtravel caused by a worn check assembly
• Reduced detent feel when opening the door
• Noisy operation from a damaged or fatigued door check
• Replacement needs after OE part wear on Trailblazer, Envoy, Rainier, or 9-7x models
