Ford Ranger / Mazda BT-50 Driver Power Window Master Switch – AB39-14540-AB

Overview

A driver-side power window master control switch for Ford Ranger and Mazda BT-50 four-door models, referenced to OE number AB39-14540-AB. The listing also names Toyota and Daihatsu applications. The master switch is the cluster of window buttons on the driver's door, and it is a well-known failure point on these utes: individual windows stop working, the switch becomes intermittent after water or dust ingress, or the auto-down function stops altogether. Because Ranger and BT-50 are among the most common utes in New Zealand, this is a steady-selling electrical repair part with a low shipping weight.

Disconnect the battery before removing the door trim, and check the window motor and regulator at the same time — a failing motor can also cause intermittent window operation. We recommend professional installation by a qualified automotive technician. Confirm the OE number, engine code and vehicle details against your vehicle before ordering, and check that the part matches the unit being replaced.
