Tutor Auto Door Lock Latch Actuator - Front Left Driver Side for GM SUVs & Trucks, OEM Fit Plug-and-Play

Tutor Auto front left (driver side) door lock latch actuator is a direct-fit replacement that restores reliable door locking and latching for compatible Cadillac, Chevrolet and GMC models.

If your driver door won't latch, the lock clicks but won't operate, or the remote no longer secures that door, the latch actuator is often the failing component. This Tutor Auto unit is built to match original mounting and electrical connections for a plug-and-play swap, helping you avoid costly dealer repairs and get back to safe, consistent door operation.

Which vehicles will this actuator fit?

This driver-side actuator is made to fit a range of early-2000s GM full-size SUVs and trucks. It covers many Cadillac Escalade model years and a long list of Chevrolet and GMC trucks, including Silverado, Avalanche, Suburban, Tahoe, and Sierra variants.

• Cadillac Escalade/Escalade EXT (2002–2006), Escalade ESV (2003–2006)
• Chevrolet Avalanche 1500/2500 (2002–2006); Silverado 1500/3500 (2001–2006) and HD/Classic variants listed in specs
• GMC Sierra 1500/1500 HD/2500 HD/3500 (2001–2006) and Yukon/XL 1500/XL 2500 (2000–2006)

How does this replace the original (OE) latch actuator?

The Tutor Auto actuator is manufactured to match OEM fitment and electrical interfaces, so installation is straightforward for someone with basic tools. It replaces several common OE part numbers used on these GM vehicles.

• Compatible with original reference numbers like 931-318, 15110643 and equivalents
• Same mounting points and connector type for plug-and-play replacement
• Designed to restore proper latch engagement and remote lock/unlock response

What symptoms indicate the actuator is failing?

A worn or broken latch actuator produces clear, repeatable symptoms that point to replacement rather than other repairs. If your door behaves inconsistently, the actuator should be inspected first.

• Door fails to latch or both exterior and interior handles won’t open the door
• Remote key fob no longer locks/unlocks the driver door or lock cycles oddly
• Unusual grinding or clicking noises when operating the door lock

Is installation difficult and what should I check before ordering?

Installation is designed to be user-friendly: the part follows factory mounting and plug connections for a simpler swap. Still, verify vehicle compatibility and OE part numbers before purchase to ensure a correct fit.

• Plug-and-play design—no major wiring or fabrication required
• Follow vehicle-specific removal procedures for door panel and linkage access
• Confirm your vehicle model/year and compare OE part numbers listed in the fitment notes

Who is this for: This Tutor Auto driver-side front door latch actuator is intended for owners and mechanics working on 2000–2007 GM full-size trucks and SUVs who need a dependable, cost-effective replacement for a failing latch motor. It’s suited to DIYers comfortable removing a door panel and reconnecting linkages, as well as independent shops seeking a reliable OE-compatible part to restore locking performance without dealer pricing.
