Description
Product Overview
This Front Left (Driver Side) Door Lock Latch Assembly is a direct replacement for 1988-2002 Chevy and GMC C/K 1500, 2500, 3500 trucks, as well as Astro vans and S10 Blazers. If your door won't latch closed, pops open while driving, or the power lock actuator struggles to engage, a worn latch mechanism is the likely cause. This complete assembly restores factory door operation with all necessary mounting points and linkage connections.

This replacement restores crisp, secure door operation with the same feel as factory. Don't wait until the door pops open on the highway. 90-day satisfaction guarantee.
Frequently Asked Questions
Q: How do I know if I need the left or right latch?
A: Left = Driver side, Right = Passenger side. This part (940-102) is specifically for the driver's door. The passenger door requires the right-side latch (940-103, sold separately).
Q: What are the symptoms of a failing door latch?
A: Door won't stay closed or latch, door pops open while driving, power locks make noise but don't engage, door ajar warning light stays on, or the interior/exterior handle feels loose and unresponsive.
Q: Is this a difficult DIY job?
A: Moderate difficulty. Requires removing the interior door panel, disconnecting linkage rods, and unbolting the old latch. Basic hand tools and approximately 1-2 hours per door. YouTube has excellent GMT400 door latch replacement tutorials.
Q: Does this work with power door locks?
A: Yes. The latch includes the correct mounting provisions for the factory power lock actuator rod. It is compatible with both manual and power lock GMT400 trucks.
Q: Will this fit a 2000 Silverado?
A: No. The GMT400 platform ended in 1999 (classic body style). 2000 and newer Silverado uses the GMT800 platform with a completely different latch design.
