Product Details

Cardone Power Window Motor 42-170 is engineered as a remanufactured O.E.-style replacement for vehicles that use a 2-terminal window lift motor. The unit is built to match factory output signals and pulse counts where applicable, and it ships in the full-up position for auto up/down applications. For drivers searching for a 2002-2005 Buick LeSabre rear left window motor, a 2000-2004 Buick LeSabre front right window motor, or a 2001-2003 Pontiac Bonneville front right window motor, this part number provides a direct-fit solution backed by Cardone’s remanufacturing process.

This part cross-references Pontiac 12481873 and 12481875 for the same application.

Common Problems This Part Can Help Solve

• Window glass moves slowly or stops before reaching the top
• Power window motor runs but the glass does not travel correctly
• Grinding, weak, or inconsistent window movement
• Window operation fails after wear in the motor or internal gears
• Noise from a worn motor assembly during window travel

Installation Notes and Tips

Install the motor only after it is fully coupled to the regulator. Do not bench-test or operate an express-up motor before installation, since doing so can cancel the upper limit position and require a reset. If the vehicle uses an anti-pinch feature, travel limits may need to be relearned after installation according to the service procedure. On 2-wire systems, direction is controlled by polarity, so wiring and switch condition should be checked if the motor runs one way but not the other.

Before replacing the motor, inspect the window regulator, tracks, weather-strip, and switch contacts. Dry tracks, worn seals, or a damaged regulator can create symptoms that look like motor failure.

Quality Assurance

Each Cardone remanufactured window lift motor is inspected, renewed, and tested to meet O.E. performance expectations. The remanufacturing process also reduces the energy and raw material needed to produce a new part by 80%, supporting a lower-waste repair choice.
