A-Premium Front Power Window Lift Motors — 2‑PC Set (Left & Right), OE-fit for GM Cars & Trucks

Two A-Premium front power window lift motors (driver and passenger) engineered to replace worn units on a wide range of Chevrolet, GMC, Buick, Cadillac, Oldsmobile and Pontiac models.

This replacement 2-piece set restores electric window operation for compatible GM vehicles from the mid-1980s through the early 2000s. Each motor is built to match OE mounting points and common reference numbers so installation is straightforward for DIYers and professional installers alike. The set includes both left and right front motors to ensure matched performance and avoid mixing old and new components.

Which vehicles will these window motors fit?

The A-Premium front left and right lift motors are designed for a broad list of GM cars, trucks and SUVs. Fitment covers many Chevrolet, GMC, Buick, Cadillac, Oldsmobile and Pontiac models across multiple years — always verify the installation side and reference numbers before ordering.

• Chevrolet: Camaro, Caprice, Cavalier, S10 Blazer, Suburban, G-series vans, K/R-series trucks and more (mid-1980s to early 2000s).
• GMC: Jimmy, C1500/C2500/C3500, Caballero and K-series trucks (mid-1980s to early 1990s).
• Buick/Cadillac/Oldsmobile/Pontiac: Century, LeSabre, Riviera, Seville, DeVille, 98, Firebird, Grand Am and others listed in the compatibility notes.
• Reference numbers: 742-150, 742150, 82-144, 82144, 42-144, 42144 and several GM part numbers for cross-checking.

How do these motors help with a stuttering or non-moving window?

Worn or failed window motors cause slow, noisy or non-responsive window movement. Replacing both front motors with new units restores smooth, predictable operation and reduces strain on window regulators and switches.

• Replaces failing motors to eliminate jerky or intermittent movement.
• Restores full power function and reduces load on the regulator assembly.
• Both sides included to ensure balanced operation and consistent travel speed.

What should I check before purchasing?

Confirm the exact model year, door location (front left or right), and compare reference numbers on your existing motor to the cross-reference list. Some GM platforms used different motors by side and year, so visual verification prevents misorders.

• Compare your old motor's part number to the listed references before ordering.
• Verify that you need front left and right motors — this set covers both sides.
• Check connector type and mounting points for a straightforward swap.

What does installation look like and what tools are typically required?

Installation usually requires removing the door panel, disconnecting electrical connectors, unbolting the motor, and transferring or aligning the regulator components. Basic hand tools and a service manual or online guide for your specific model make the job faster and safer.

• Common tools: screwdriver set, ratchet and sockets, trim removal tools, and possibly pliers.
• Allow 1–2 hours per door for a DIY installer comfortable with door disassembly.
• Keep hardware and regulator alignment intact for smooth window travel after installation.

Who is this for: This A-Premium 2-piece front window motor set is intended for owners, mechanics and restoration shops working on classic to late-model GM vehicles that match the compatibility list. It suits anyone replacing worn window motors who wants matching left/right units, OE-style mounting, and a straightforward swap to return reliable power-window function.
