A-Premium Door Lock Actuator Set of 2 for GM Vehicles — No Dirt-Proof Boot, 2-Pin Direct Replacement

This pair of A-Premium actuators is a direct-replacement style for a wide range of General Motors cars, trucks and SUVs from the mid-1980s through the early 2000s. Each actuator uses a two-pin connector and is supplied without a dirt-proof boot, so installation is straightforward for mechanics and knowledgeable DIYers who confirm fitment before ordering. The set covers left and right, front and rear positions on many Buick, Cadillac, Chevrolet and GMC models, and includes multiple OEM reference numbers to help cross-check compatibility.

Which vehicles will these A-Premium actuators fit?

These actuators are engineered to match the mounting and connector patterns used across many GM platforms. Fitment includes numerous Buick, Cadillac, Chevrolet and GMC model years primarily from 1985–2005; review your vehicle specifics and the listed reference numbers to verify fit. They suit both front and rear door locations depending on the application.

• Buick: Reatta, Riviera, Regal, Skylark, Electra, Century, LeSabre and related years
• Cadillac: Seville, DeVille, Eldorado and select Escalade years
• Chevrolet & GMC: Astro, S10/Blazer, Tahoe, Suburban, C/K trucks, Yukon, Jimmy, Safari and others
• Multiple OEM reference numbers included for cross-reference (e.g., 16603085, 20474092, 22071946)

How do these actuators install and connect?

Installation requires removing the door panel and replacing the faulty actuator with the new unit; the actuators use a two-pin electrical connector and standard mounting points. Because these units are shipped without a dirt-proof boot, take care to ensure the door cavity stays dry and clean during installation. If replacing both sides, the included pair covers driver and passenger or front and rear positions as needed.

• Two-pin connector for direct electrical hookup
• Mounts to existing door bracket locations—match hole pattern
• No dirt-proof boot included—verify door sealing and insulation
• Packed as a set of two for left/right or front/rear replacements

What performance and durability should I expect?

A-Premium actuators are built to provide consistent locking and unlocking cycles comparable to original equipment. They deliver motor-driven actuation with metal linkage mounting points typical of OEM units. Performance can vary with vehicle wiring condition and how dry the door interior remains, so addressing moisture paths and worn linkages at installation helps maximize service life.

• Motor-driven operation for reliable lock/unlock
• Compatibility with OEM linkage and bracket geometry
• Durability depends on door cavity conditions and wiring health
• Sold as a matched pair to ensure symmetric operation

How do I confirm I’m ordering the correct actuator?

Before purchasing, enter your vehicle information and double-check the install location listing. Compare the actuator’s connector count, mounting orientation and the OEM reference numbers against your existing part. If uncertain, remove the door panel to inspect the old actuator or consult a trusted technician for verification.

• Use the vehicle lookup box and check listed locations
• Confirm the part’s two-pin connector matches your harness
• Match reference numbers shown to the original part if available
• Inspect the physical mounting points for correct alignment

Who is this for: This A-Premium 2-pack is aimed at vehicle owners, restoration projects and repair shops replacing failed power door lock actuators on classic and late-model GM vehicles. It’s ideal for buyers who need a cost-effective, direct-fit replacement for left/right or front/rear positions and who are prepared to install parts without a protective dirt-proof boot, or to add their own sealing solutions during installation.
