Detailed Description

This Dorman 15803 window crank handle replaces the original equipment handle on select Mazda B2300, Mazda B2500, Mazda B3000, and Mazda B4000 models. The clip-on shaft attachment and 16-spline design support a secure fit on the correct manual window regulator shaft, while the gray plastic construction matches a clean OE-style appearance. This part cross-references Monroe Shocks & Struts (e.g., UH7158580) for the same application.

What It Helps Fix

• Broken or cracked window crank handle
• Loose handle that slips on the shaft
• Difficult manual window operation
• Worn spline engagement at the crank connection
• Interior trim mismatch after handle replacement

Installation Notes and Tips

Verify the 16-spline count and 12.9 mm mounting shaft diameter before installation. This handle uses a clip-style shaft attachment, so confirm the regulator shaft style on the vehicle before ordering. For best results, compare the original handle shape, arm dimensions, and color to the replacement part before installation.

Quality Assurance

Dorman manufactures this replacement handle as a durable OE-style service part for manual window repair. Part number 15803 is built to restore normal window crank function on the listed Mazda applications.
