🚗 What To Do When Your Power Windows Fail: Common Issues & How To Fix Them

Imagine you're driving on a scorching Aussie summer day and your car window refuses to budge.

Or worse — you're cruising with the windows down, enjoying the breeze, when it suddenly starts to rain... and your window won’t go back up. Whether it's stuck open or closed, it’s a situation no one wants to be in.

 

These kinds of problems are often caused by a failing power window motor or a faulty window switch. In this guide, we’ll show you how to diagnose and deal with common power window issues — so you can stay in control, no matter the weather.


🔧 What Is a Power Window Motor?

The power window motor is a small electric component inside your car door that raises and lowers the window at the press of a button. It works in tandem with the window regulator to ensure smooth and reliable window operation.

Nearly every modern vehicle on Australian roads uses power windows — they're convenient, but when something goes wrong, it can quickly become a major inconvenience.



 

⚠️ Common Signs of a Failing Power Window Motor

  • 🚫 Window won’t move at all when you press the switch
  • 🐢 Slow or jerky window movement
  • 🔊 Grinding, clicking, or humming noises from inside the door
  • 🔁 Window gets stuck halfway up or down

These symptoms often point to a worn-out motor, faulty regulator, or a failing power window switch.

🧰 Diagnosing the Issue

  • Check all windows: If none work, the issue may be electrical. If just one, focus on that door’s motor or regulator.
  • Listen for motor noise: A hum with no movement could mean a jammed regulator.
  • No sound at all? Likely a burnt-out motor or electrical fault.


🛡 Safety First: Prepping for the Job

  • Disconnect the car battery before starting any repairs.
  • Wear safety glasses when working inside the door cavity.
  • Check your vehicle’s manual for panel removal instructions.


🛠 Accessing the Window Motor

  1. Remove the door panel carefully.
  2. Peel back the vapor barrier to access components.
  3. Locate the motor and regulator assembly.

⚠️ Tip: Work slowly and keep screws and clips organised.

💡 Dirty or Corroded Connections

Clean with contact cleaner and a wire brush.

🔄 How to Replace a Power Window Motor

  1. Disconnect the electrical plug.
  2. Secure the window to prevent it from falling.
  3. Unscrew and remove the old motor.
  4. Install and bolt in the new motor.
  5. Reconnect wiring and test operation.

Always refer to your vehicle's service manual for exact steps.



✅ Reassembly and Testing

  • Reinstall the vapor barrier.
  • Reattach the door panel and secure all clips.

  • Don’t hold down the switch when the window is fully closed/open.
  • Address unusual sounds immediately.
