Product Details

Cardone Power Window Motor 42-1045 is part of the brand’s remanufactured window lift motor line, which focuses on OE fit, renewed internal components, and verified performance. Each unit is assembled with the proper lubricant for quieter operation and longer service life, while internal gears are inspected and renewed or replaced with stronger material when needed. For vehicles with auto up/down functions, output signals and pulse counts are matched to the application.

This part cross-references Isuzu 8889809860 for the same application. Fits 2004-2012 Chevrolet Colorado, rear left; fits 2004-2012 GMC Canyon, rear left; fits 2007-2008 Isuzu i-370, rear left; fits 2006 Isuzu i-350, rear left.

Common Problems This Part Can Address

• Rear window does not move up or down
• Slow, weak, or intermittent window operation
• Motor runs but the glass does not travel correctly
• Noisy or rough window lift operation caused by worn motor components
• Auto-up or auto-down function not responding as expected after motor failure

Installation Notes

Install the motor only after it is fully coupled to the regulator. Do not bench-test or operate an express-up/express-down motor before installation, since doing so can cancel the travel limits and require a reset. If the vehicle uses an anti-pinch system, the motor may need to be relearned or reset after installation according to the service procedure.

Before replacing the motor, inspect the window regulator, tracks, weather-stripping, switch contacts, and wiring. On 2-wire systems, direction is controlled by polarity, so a one-direction-only condition can point to a switch or wiring fault rather than the motor itself.

Quality Assurance

Each Cardone remanufactured window lift motor is tested, inspected, and renewed to match original equipment performance. The remanufacturing process reuses suitable cores, replaces worn internal parts, and supports a lower-material, lower-energy repair path than manufacturing a new part.
