Manual Trunk Latch Lock Actuator 4-Pin Compatible with Buick GM SUVs

In this review the reviewer focuses on a replacement manual liftgate trunk latch actuator intended for owners of Buick, Cadillac, Chevrolet, GMC, Pontiac and Saturn SUVs that require a 4-pin connector. The bottom line is practical: this part is for vehicles without a power liftgate and is a straightforward, cost-conscious replacement that typically restores function quickly. The reviewer found it most useful where fitment and simple installation matter more than factory-original finish, making it a sensible buy for DIY repairs or a small shop replacement.

Key Features

• 4-pin connector only: Ensures direct compatibility with vehicles that use the 4-pin harness, avoiding the need for splicing when the original part used the same connector.
• Manual liftgate design: Fits models without power liftgate systems, providing the correct actuator for manually operated rear tailgates.
• Wide vehicle fitment: Covers many GM SUVs including Enclave, Escalade, Yukon, Acadia, Equinox and Traverse, helping shoppers find a single replacement across several model lines.
• Reference numbers included: Matches multiple OEM reference numbers so technicians can cross-check fit before purchase.
• One-year guarantee: Backed by a one-year unlimited-mileage warranty, offering reasonable assurance against early failures.

Who It's For

This actuator is aimed at owners and independent mechanics who need a direct, affordable replacement for a failed trunk latch on GM SUVs that have a manual liftgate and a 4-pin connector. It suits model years listed for Buick Enclave, Pontiac Torrent, Saturn Vue, Cadillac Escalade and SRX, and many GMC and Chevrolet SUVs where the original part is nonpowered.

It is not for vehicles equipped with a power liftgate or a 6-pin connector; those customers should look for a power-compatible actuator. Also, buyers seeking an exact OEM cosmetic match or a high-end factory-refinish part may prefer dealer-sourced options instead of this aftermarket unit.

Pros & Cons

Pros

• Simple 4-pin connector avoids complex rewiring when replacing like-for-like actuators.
• Backed by a one-year unlimited-mileage guarantee for peace of mind after purchase.
• Often easier to install than expected, making it a practical DIY replacement.

Cons

• Build quality reviews are mixed, so durability may vary compared with original equipment parts.
• Not compatible with power liftgate systems or 6-pin harnesses, so buyers must confirm connector type.
