Front Left Driver Window Regulator w/ Motor for Ford F150 04-08

In this review the focus is on a direct replacement front left driver side window regulator with motor for Ford F150 model years 2004 through 2008. It is aimed at DIY owners and independent repair shops who need a reliable, OEstyle substitute for a failing power window assembly. The bottom line: the part fits the specified Standard or Crew Cab doors with 43.5' wide openings and restores smooth, quiet operation without the premium cost of dealer parts.

Key Features

• Direct fit: Designed to match the original mounting points so it installs without modification and reduces labor time.
• OE compatibility: Matches factory OE numbers such as 741-428 and 4L3Z1523201BA so buyers can confirm fitment for the listed years and models.
• Integrated motor: Includes the motor and regulator as an assembly to avoid sourcing separate components and to ensure coordinated operation.
• Quiet operation: Built to OE standards so the window slides smooth and quick without excessive noise during use.
• Vehicle coverage: Fits 2004-2008 Ford F150 (Standard or Crew Cab with 43.5' doors) and 2006-2008 Lincoln Mark LT front left applications for targeted compatibility.

Who It's For

This part is for Ford F150 and Lincoln Mark LT owners who are comfortable performing a door panel removal and wiring connection or who work with a local mechanic. It is especially appropriate when the original regulator has failed, the window is stuck or moves unevenly, or the motor is noisy.

It is not for extended cab F150s or vehicles with different door widths, so buyers should verify the 43.5' door requirement before purchase. Customers who prefer factory dealer parts or warranty-backed installations may choose to source an OEM part instead.

Pros & Cons

Pros

• Direct replacement fit reduces installation complexity and time for compatible doors.
• The assembly includes a motor, removing the need to match separate components.
• Customers report good build quality and that it performs like the original unit.

Cons

• Does not fit extended cab models or doors that are not the 43.5' width, so fitment verification is required.
