Purpose and vehicle placement

The presented window regulator is designed for installation in the front left door of the vehicle, in the area responsible for the comfort of the driver or front passenger. Placement in the Front - left area allows for precise alignment with factory mounting points and proper cooperation with the electrical installation and door trim. The component belongs to the Window regulators and motors group, which means it is responsible for the smooth guidance of the window along the rails and keeping it stable in the set position. This enables comfortable use of the window opening and closing function without excessive vibrations or jamming.

Technical and functional characteristics

The window regulator works with the factory window control system in the door, ensuring:

• proper power transmission from the motor to the lifting mechanism,
• stable vertical window guidance,
• maintenance of proper tension for cables or guide elements,
• compatibility with the original door construction of the Ford Focus Mk3 5-door version. Thanks to maintaining geometry consistent with the factory design, the installation proceeds in an orderly manner, and the mechanism works in a predictable and repeatable way after correct installation. This is particularly important during daily vehicle use, where reliability and the absence of unwanted noises from inside the door are essential.

Component condition and benefits of choosing a used part

The window regulator is offered in used condition, which allows for combining a reasonable purchase cost with maintaining parameters close to factory specifications. Parts of this type usually come from the dismantling of vehicles where the window system worked correctly, thanks to which they can be successfully used as a replacement for a damaged mechanism. Choosing a used component from the Window regulators and motors group is a solution often preferred for maintenance repairs, where it is crucial to restore full functionality while maintaining a rational service budget.

Part selection by numbers and technical aspects

When selecting a window regulator for the Ford Focus Mk3, it is worth paying attention to compliance with the manufacturer's markings and the placement on the vehicle. Proper fitment to the 5-door body version and the installation side minimizes the risk of installation problems and ensures proper cooperation with other door components.
