Detailed Description

Dorman 748-922 is a direct replacement window motor and regulator assembly for the rear left position on 2000-2004 Nissan Frontier trucks. The assembly is designed around the original equipment layout so the window mechanism, motor operation, and mounting points align with the factory configuration. This helps restore normal window travel when the original regulator or motor has worn out, stripped gears, or lost power.

The assembly uses a plastic gear and a bolt-on attachment design. Mounting hardware is included, while installation instructions are not. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Part number 748-922 is also referenced by 11A649, 380238, 827212S710, and WLR2217.

Common Repair Uses

• Rear left power window will not raise or lower
• Window moves slowly, unevenly, or stops partway
• Grinding or slipping from a worn regulator gear
• Motor runs but the glass does not move correctly
• Factory regulator assembly has failed on a Nissan Frontier

Installation Notes

Verify vehicle year, make, model, and rear left position before installation. This assembly uses a bolt attachment style and includes mounting hardware, which supports a straightforward replacement process on the listed Nissan Frontier applications. Because installation instructions are not included, compare the new assembly to the original unit before removal and transfer any required trim or glass-related components according to the vehicle service procedure.

Quality Assurance

Dorman manufactures this replacement assembly to match the stock window regulator’s fit, function, and performance on the specified vehicles. It is extensively tested during development to support consistent operation in the intended application.
