If your BMW X1’s back window won’t go up, it’s more than just annoying — it’s a real problem that can affect safety, comfort, and even your car’s electronics if left open during bad weather. In this guide, we’ll walk you through the most common causes, what you can do to fix it, and when it’s time to call a professional.
Why Won’t the Back Window Go Up on a BMW X1?
The most common reasons your BMW X1’s back window won’t close include:
- Faulty window regulator – the motor may run, but the window won’t move.
- Burnt out window motor – the motor may have failed entirely.
- Broken or jammed window track – something might be blocking the window’s path.
- Blown fuse or relay – the electrical circuit isn’t getting power.
- Faulty window switch – the button might be worn or disconnected.
This is a common issue across various BMW models due to the complexity of their power window systems. For more info on how BMW uses tech in their vehicles, check out these expert guides on BMW’s tech features.
How to Troubleshoot the Problem
Here’s how to diagnose what’s going wrong with your back window:
- Listen for a sound: Press the window switch. If you hear a motor noise but the window doesn’t move, the regulator is likely broken.
- No sound at all? Could be a dead motor, blown fuse, or bad switch.
- Try the master switch: Use the driver’s control panel to see if the window responds.
- Check for obstructions: Look down into the door to see if something is blocking the track.
Quick Tip: If you hear a clicking sound or see the window moving slightly but it doesn’t go all the way up, the regulator might be slipping or partially broken.
What Is a Window Regulator and Why Does It Fail?
The window regulator is a mechanism inside the door that moves the glass up and down when you press the switch. It’s connected to a small electric motor. Over time, the cables inside the regulator can wear out, snap, or come loose — especially in the rear doors that get less use but still face wear from vibration and temperature changes.
Signs of a bad regulator include:
- Window moves crooked or gets stuck halfway
- Window falls down into the door suddenly
- Grinding or clicking noises during operation

How to Temporarily Close the Window
Need a quick fix before heading to the repair shop? Here’s what you can try:
- Use your hand: Gently press the window upward while pressing the switch — sometimes it’ll catch and move.
- Turn the ignition on and off: Resetting the car’s electronics may restore switch function temporarily.
- Use plastic or waterproof covering: If it won’t close, seal the window opening with plastic and tape to keep water out.
Warning: Never force the glass or pry inside the door without knowing what you’re doing. You can damage the regulator or crack the window.
Can I Fix It Myself?
If you’re comfortable with basic car repairs, you might be able to fix a stuck back window on your BMW X1 yourself. Here’s a general DIY plan:
- Remove the door panel carefully using a trim removal tool
- Inspect the regulator and motor for broken cables or disconnected parts
- Replace the faulty part (motor or regulator)
- Reconnect all wiring and test before reinstalling the panel
You’ll need a basic socket set, trim tools, and patience. Replacement regulators typically cost between $70 and $200 depending on the model year.

What Does a Repair Shop Charge?
Here’s what you might expect to pay at a mechanic or BMW dealership:
| Repair Type | Estimated Cost |
|---|---|
| Window regulator replacement | $250 – $450 (parts + labor) |
| Window motor replacement | $300 – $500 |
| Fuse or switch repair | $100 – $200 |
Labor rates vary by location, and dealerships usually charge more than independent BMW specialists.
Can the BMW Window Be Reset?
Yes, in some cases. After replacing or disconnecting the battery, windows may lose their automatic function. Here’s how to reset the window:
- Turn the ignition to accessory or “on” mode (engine off)
- Press the window switch all the way down and hold for 5 seconds
- Then press the switch all the way up and hold again for 5 seconds
This trains the window to learn its new limits. If it still won’t move, the issue is likely mechanical or electrical.
Conclusion
If your BMW X1’s back window won’t go up, it’s likely due to a failed regulator, motor, or a wiring issue. You can troubleshoot it yourself with a few simple checks, but if the problem involves broken parts inside the door, a professional repair is often the best option. Ignoring the issue could expose your interior to damage or compromise your car’s security.
