Component Location & Fastener Locations
A quick and direct guide showing you the exact location and mounting fasteners for the power window regulator and motor assembly on a 2013-2022 Buick Encore. Once the inner door panel, moisture vapor barrier, and window glass are removed or safely secured in the up position, the scissor-and-cable style regulator mechanism is accessed entirely inside the hollow inner door cavity.
- Regulator Track Bolts: Located along the inner steel door skin. The vertical dual-guide tracking rails are secured by four 10mm nuts/bolts passing through the sheet metal.
- Window Motor Bolts: Located on the lower middle section of the door panel. The motor gearbox assembly is held in place by three 10mm bolts.
- Electrical Connector: Positioned directly on the window motor body, featuring a push-down locking tab and a gray slide-lock clip.
DIY Friendly Repair Guide
If you are planning to change out a dead window motor or a binding cable regulator yourself, knowing the bolt pattern and the best angle to slide the assembly out of the lower service cavity is half the battle. After loosening the glass sash clamps and taping the window glass securely to the upper frame, unbolt the track and motor fasteners. The entire integrated regulator and motor assembly can then be collapsed slightly and maneuvered out through the largest stamped service opening at the bottom of the door frame. This guide is designed to save you time and prevent you from bending the new tracks during installation, making your DIY auto repair much smoother.
Common Bad Symptoms
When a window regulator or its electric motor fails, you might experience several warning signs. Common symptoms include a window glass that refuses to move up or down when you press the switch, a loud grinding, binding, or crunching noise inside the door card (indicating the steel tracking cables have snapped or bird-nested inside the reel), or a window that drops completely into the door skin on its own. You might also notice the window moving exceptionally slowly, stopping halfway up, or bowing sideways because the plastic slider blocks have cracked.
Safety First!
Before you start working on your vehicle, always prioritize safety. Because you are working inside a door skin with sharp sheet-metal edges and dealing with heavy glass, you must securely tape the window glass to the top door frame using heavy-duty painters tape or suction cups before unbolting the regulator to prevent it from crashing down and shattering. Always disconnect the negative battery cable before unplugging the electric motor harness to avoid short circuits or unexpected pinches, wear proper eye protection and mechanics’ gloves, and ensure your working environment is safe before performing any vehicle maintenance.
