Product Overview

The master power window switch, OEM number LR078894, is the driver-side control panel that operates the window motors for all doors, letting the driver raise and lower any window from a single location. It is used constantly throughout the life of the vehicle, and its internal contacts and buttons wear with repeated use, which makes it a regular replacement item in the electrical and interior controls category.

A worn or faulty window switch can cause windows to stop responding or work intermittently, so a properly functioning replacement matters. GSK Auto manufactures this window switch to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm the OEM number match before shipping.

What Is a Master Power Window Switch?

Function: The master power window switch lets the driver control the power windows for every door in the vehicle from one central panel, and often includes child lock and window lockout functions.

Working Principle: Each button on the switch panel closes an electrical circuit that sends power to the corresponding window motor, running it in the up or down direction depending on how the button is pressed. The master switch also typically includes a lockout button that disables the rear window controls from the individual door switches.

Importance: As the primary control point for all power windows, the master switch is essential for convenient and safe window operation. A failing switch can leave one or more windows unresponsive or stuck.

Common Failures & Signs: One or more windows not responding to the switch. Windows operating slowly or intermittently. Buttons that stick or feel loose. Window lockout function not working correctly. Backlighting on the switch panel not illuminating. Windows operating on their own without input.
