NPAUTO Front Power Window Regulator w/Motor for Chevy GMC 1999–2007 — Driver & Passenger Pair, OE-Fit Direct Replacement

Complete front driver and passenger power window regulator assemblies with motors designed to replace worn or broken units on Chevy, GMC and Cadillac trucks and SUVs from 1999–2007.

When a window sticks, drops, or won’t move, the regulator and motor assembly is usually the culprit. NPAUTO’s front left and right power window regulator assemblies are built to OE-style specifications to restore smooth, quiet window operation for Silverado, Sierra, Tahoe, Suburban, Yukon, Avalanche and select Cadillac Escalade models from 1999 through 2007. Each assembly includes the motor and mounting points for a direct-fit swap, reducing installation time and getting you back on the road with reliable function.

How do I know this fits my vehicle?

These assemblies are manufactured to match the original equipment mounting pattern and electrical connector types used on many GM trucks and SUVs from 1999–2007. The listing covers both driver (left) and passenger (right) front positions and includes the most common OEM part numbers for cross-reference.

• Fits: Silverado 1500/2500/3500 (including HD, Classic), Sierra 1500/2500/3500, Avalanche 1500/2500
• Also fits: Suburban, Tahoe, Yukon (incl. XL), and Cadillac Escalade ESV/EXT where applicable
• OE cross numbers included for easy match against your existing part
• Units come with the motor pre-attached for direct replacement

What should I expect during installation?

Installation is straightforward for anyone comfortable removing a door panel and swapping assemblies. The regulator is a direct replacement designed to line up with factory mounting points and plug into the original wiring harness, minimizing modifications.

• Remove door trim panels and disconnect battery before starting
• Unbolt the old regulator, unplug the motor connector, then fit the new assembly in reverse order
• No cutting or drilling required when used on listed models
• Professional or experienced DIY installation typically takes 1–2 hours per door

How does this improve window performance?

Replacing a worn regulator and motor restores smooth travel, reduces grinding or jerking, and prevents windows from falling into the door. The assemblies are engineered to operate quietly and reliably, matching the movement speed and fit of the factory part.

• New motor restores consistent torque for steady window movement
• Precision gear and cable components reduce noise and binding
• Durable mounting points preserve alignment over time
• Tested to meet OE fit and movement characteristics

What warranty and support come with the part?

Each unit is backed by a 2-year warranty and NPAUTO customer support. If you encounter fitment questions or need help identifying the correct side, the support team can assist with part verification and installation guidance.

• 2-year limited warranty from purchase date
• Dedicated customer service for fitment and technical questions
• OE-style packaging and protective shipping to reduce transit damage
