Power Window Switches

Power window switches for heavy-duty and industrial vehicles

In this category on enriquerequena.com you will find a specialized selection of power window switches for trucks, buses, and industrial vehicles. These electrical and cab components control the window regulator motors safely and reliably, ensuring cab comfort and daily operability in professional environments.

Our catalogue is aimed at workshops, fleets, and maintenance professionals who need compatible parts for fast replacement. Replacing a faulty switch prevents actuation failures, poor contacts, and electrical issues within the door panel system.

Key points when choosing the correct power window switch

  • OEM reference: Match the original part number to ensure full compatibility.
  • Mounting location: Check whether it is for the driver door, passenger door, or a central control unit (depending on cab layout).
  • Number of buttons and functions: Differentiate between single/double switch, child lock, “auto” up/down, or multi-window control.
  • Connector type: Verify plug shape, pin count, and wiring layout to avoid modifications.
  • Model/year compatibility: Confirm make, model, year, and cab version, as door harnesses can differ.

Frequently Asked Questions

What symptoms indicate a faulty power window switch?

Common symptoms include the window not moving up or down, intermittent operation, having to press hard, or movement in only one direction. Moisture ingress and worn internal contacts can also cause failures.

Is the issue always the switch, or could it be the window motor?

Not always. The fault may be in the motor, mechanism, fuse/relay, or door wiring. Professional diagnosis typically checks power supply and continuity before replacing the switch.

Are left-hand and right-hand switches different?

Yes. On many vehicles, the driver master switch includes additional features (multi-door control, lock, auto function), so it is often not interchangeable with the passenger switch.

Do I need coding or calibration after replacement?

In most heavy-duty vehicles, no. However, if “auto” or anti-pinch functions are present, a window re-learn procedure may be required after installation, depending on the manufacturer.
