Detailed Description

Cardone 42-171 is a remanufactured window lift motor designed for vehicles that need an OE-style replacement without changing the original mounting or regulator setup. It is built from original equipment cores, then re-engineered and tested to match factory performance. The part number 42-171 is used across multiple applications, including Buick LeSabre, Pontiac Bonneville, Oldsmobile Aurora, Oldsmobile Alero, and Pontiac Grand Am window motor replacements.

For vehicles with auto up/down operation, the motor is shipped in the full up position and output signals are matched to the application. This helps maintain proper window travel and switch behavior after installation. This part cross-references Pontiac 12481874 and 12481876 for the same application.

Common Problems This Part Can Address

• Power window glass that will not move up or down
• Slow, weak, or inconsistent window travel
• Window motor noise caused by worn internal components

Do not bench-test an express-up or anti-pinch motor before it is fully coupled to the regulator, since doing so can cancel the upper limit position. If the motor is disturbed from its factory-set position, travel limits must be reset using the vehicle service procedure. For 2-wire motors, verify switch and wiring polarity before replacing the part.

Quality Assurance

Each Cardone remanufactured window lift motor is 100% tested, including load testing on a simulated window fixture. Internal parts are inspected and gauged, gears are renewed or replaced when out of spec, and the motor is assembled for quiet, reliable operation. The remanufacturing process also reduces raw material and energy use compared with producing a new part.
