Detailed Description

The WMR4642L window regulator is built for vehicles equipped with a manual front left window system. Use it when the driver-side window no longer travels correctly, binds in the door, or will not stay aligned in the track. This part number is a fitment-specific replacement for Chevrolet Cobalt and Pontiac G5, G4, and Pursuit models listed above, making it a practical choice for restoring normal window operation.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Window crank turns but the glass does not move properly
• Slow, uneven, or sticking window travel
• Window glass that drops into the door
• Broken or worn regulator mechanism in the front left door
• Misalignment that prevents the window from raising or lowering smoothly

Installation Notes and Tips

Verify that the vehicle uses a manual front left window regulator before ordering. Compare the original regulator shape, mounting points, and cable or track layout to confirm a proper match for WMR4642L. After installation, test full up-and-down travel to ensure the glass moves evenly and seats correctly in the door frame.
