Product Details

CARDONE’s Power Window Motor and Regulator Assembly line focuses on replacing the motor and regulator together when the original regulator has worn enough to overload the motor. That approach helps address the root cause of slow, noisy, or inoperative windows instead of replacing only one component. Part number 82-178BR is engineered for the rear left position and is listed for 1999-2007 Chevrolet Silverado and GMC Sierra models, plus Cadillac Escalade, Escalade ESV, Escalade EXT, Avalanche, Suburban 2500, and Yukon XL 1500/2500 applications shown in the fitment data.

This part cross-references Chevrolet and GMC OE number 15135970 for the same application.

Common Problems This Part Can Address

• Rear left window will not move up or down
• Window movement is slow, uneven, or noisy
• Motor failure caused by a worn regulator assembly
• Stripped gears or broken internal drive components
• Intermittent operation from worn window lift parts

Installation Notes

Verify the rear left position and compare the original mounting style, connector, and regulator layout before installation. This assembly uses threaded mounting with five mounting holes and includes the motor with regulator pre-assembled for the listed applications. Confirm vehicle year, make, model, and trim against the fitment data before ordering.

Quality Assurance

Each unit is load tested and assembled with the proper lubricant amount to support quiet operation and long service life. CARDONE engineers this window motor and regulator assembly to meet or exceed OEM performance standards for dependable operation in the listed Chevrolet Silverado, GMC Sierra, and Cadillac applications.
