If the window on your 2003 BMW X5 won’t go up, you’re not alone. Power window issues are common in older BMW models and can be caused by several things — from a bad switch to a broken regulator. Whether your window is stuck halfway or completely down, this guide will help you understand the problem and how to fix it.
Why Won’t the Window Roll Up on a BMW X5?
If your BMW X5’s window won’t go up, the issue could be electrical or mechanical. The most common causes include:
- Window regulator failure: The regulator is what moves the window glass up and down — they often break in older BMWs.
- Faulty window switch: The switch may stop sending power to the window motor.
- Burned-out window motor: The motor may fail due to age or wear.
- Broken or frayed wiring: Especially inside the door or in the rubber boot between the door and car body.
- Blown fuse: A fuse may be blown, especially if multiple windows stop working.

How to Diagnose the Problem
Follow these steps to find out what’s causing your window to stay down:
1. Listen for the Motor
- Press the window switch and listen closely.
- If you hear a motor running but the window doesn’t move, the regulator is likely broken.
- If you hear nothing, the issue could be the switch, motor, or wiring.
2. Try the Switch from Both Driver and Passenger Sides
- If both switches don’t work, it’s probably the motor or regulator.
- If one switch works but the other doesn’t, the switch is likely the problem.
3. Check for Physical Resistance
- Gently pull up on the window glass while someone presses the switch.
- If it starts to move, the regulator is weak or off track.
4. Inspect the Fuse Box
- Look for any blown fuses related to the power windows.
- Fuse locations are typically found in the glove box or trunk panel.
5. Remove the Door Panel (if needed)
- If you’re comfortable with tools, remove the door panel to inspect the motor and regulator.
- Look for snapped cables, plastic bits, or a dislodged track.

Window Regulator: The Most Common Failure
In the 2003 BMW X5, window regulators are a known weak point. They’re made of plastic and tend to break or snap over time, especially if the window is used frequently. Signs of a broken regulator include:
- Window drops down suddenly
- Grinding or clicking noise when pressing the switch
- Window gets stuck halfway or tilts while moving
If the regulator is the issue, it will need to be replaced. Many BMW owners replace regulators themselves to save on labor costs.
Repair Costs and Options
| Repair Type | Estimated Cost |
|---|---|
| Window regulator (parts only) | $50 – $150 |
| Window motor replacement | $100 – $300 |
| Switch replacement | $30 – $100 |
| Professional labor (per window) | $150 – $250 |
DIY repair can save you a lot, especially if it’s just the regulator or switch. However, if you’re unsure about removing door panels, it may be best to have a shop handle it.
Tips to Prevent Future Window Problems
Here’s how to reduce the chances of more window failures in your BMW X5:
- Avoid slamming the door with the window halfway down
- Don’t force the switch if the window sticks — it can damage the regulator
- Clean and lubricate window tracks every year
- Replace any slow or noisy window regulators before they fail completely
