The Bayerische Motoren Werke AG, more commonly known as BMW, has etched itself as a luxurious car manufacturer brand. Owners can attest that owning a BMW is a symbol of luxury and style however, it’s far from perfect. Like any vehicle, BMWs are not immune to occasional vehicular or mechanical issues.
One frustrating problem that BMW owners may encounter is when their car window won’t go up. Whether it’s due to a technical glitch, a power window malfunction, or other factors, dealing with a stuck window can be a frustrating situation.
In this comprehensive guide, we’ll explore the things you can do as someone who owns a BMW that suffers from having its windows won’t go up, how to reset the power window system, how to manually roll up a BMW window, and common reasons why your BMW window may not be working.
What Do You Do When Your BMW Window Won’t Go Up?
When facing a non-responsive window of a vehicle, most owners would immediately assume that it’s a mechanical problem and has a tendency to panic. This will then lead to disruptive decisions that can potentially do more harm than good.
Situation as such can be perplexing, but the first step is to remain calm. Panicking won’t solve the problem, but following these steps will help you troubleshoot the issue effectively:
Check the Window Switch: Start by visually examining the window switch, the open slot, and the rubber matting on the door panel. Ensure it’s not stuck or damaged. Sometimes, a malfunctioning switch can be the root cause.
Inspect the Wirings: Worn out wirings, shorted connection, or a chewed-out cables are some of the uncommon issues that can easily be overlooked by car owners.
If the connection that provides power to your windows motor is faulty or broken, then you may need to either reconnect them or replace them depending on the severity of the damage.
In this case, visually inspect all wirings that provides power to your window.
Inspect the Fuses: Locate the fuse box in your BMW, often found in the glove compartment or trunk. Check the fuse associated with the power windows and replace it if it’s blown.
The location of this fuse can vary depending on your BMW’s model and year, so refer to your owner’s manual for guidance.
Listen for Motor Noise: When you press the window switch, listen for any sounds from the window motor. If you hear a noise, it’s likely the motor is functional, but the window might be off its track or obstructed.
Try Other Windows: If only one window is affected, try operating the other windows. If they work fine, it’s likely an isolated issue with that particular window. Otherwise, the problem could root from power related issues.
Battery Check: In every electronics, low battery voltage can affect the functionality or stability of the power that operates your windows. Ensure your car’s battery is in good condition and fully charged. If the battery is weak, recharge or replace it.
Inspect for Obstructions: Look for any debris or obstructions along the window tracks or in the window frame. Even small objects can prevent the window from closing properly.
Manually Roll Up the Window: If none of the above steps resolve the issue, if your BMW allows, try to manually roll up the window as a temporary solution until the problem is fixed.
If the problem still persists after performing the steps, we indicated above, then we highly recommended to have it checked by a qualified mechanic or bring your car back to your dealer to have them fix it for you.
Just be ready to shell out some money if your BMW is out of warranty. We’ll delve into this further later in the article.

- Depending on your BMW’s design, you may need a socket wrench or screwdriver to manually turn the window regulator.
- Rotate it in the direction that closes the window.
- Be patient and gentle to avoid causing further damage.
- Roll Up the Window:

Why is My BMW Window Not Working?
Understanding the reasons behind a malfunctioning BMW window is crucial to prevent future issues and ensure your safety. However, the root cause could be more complex or a cascading factor that contributes to the issue at hand.
With this in mind, there are several factors that you need to consider as these can contribute to a non-responsive window:
Window Regulator Failure: The window regulator is responsible for moving the window up and down. Over time, it can wear out or break, causing the window to become stuck.
Window Motor Issues: The window motor is another critical component of the power window system. If it fails or experiences electrical problems, your window may not operate.
Electrical Problems: Faulty wiring, blown fuses, or a malfunctioning window switch can disrupt the electrical supply to the window motor, preventing it from functioning correctly.
Window Off Track: If the window comes off its track, it can become misaligned and unable to move smoothly. This can happen due to wear and tear or physical force.
Obstructions: Debris, ice, or objects lodged in the window track can obstruct the window’s movement and prevent it from closing.
Window Seal Damage: Damaged window seals can allow moisture to enter the window mechanism, leading to corrosion and operational problems.
Faulty Control Module: In some cases, a malfunctioning control module, responsible for managing various electrical functions, including power windows, can be the culprit.
Battery Issues: A weak or dying battery may not provide sufficient power to operate the windows.
Window Tinting: Excessive or improper window tinting can interfere with the window’s sensors, causing it to malfunction.
Extreme Temperatures: Very hot or cold weather can affect the power window system’s performance.
When faced with a non-functioning BMW window, it’s essential to diagnose the specific cause to address the problem effectively. If you’re not confident in your troubleshooting skills, consult a BMW dealership or a certified technician for professional assistance.
Final Thoughts
Dealing with a BMW window that won’t go up can be frustrating, but it’s a challenge that can be overcome with patience and the right approach. Start by checking the window switch and fuses, listen for motor noise, and inspect for obstructions.
If these steps don’t resolve the issue, consider performing a power window reset. In cases where manual intervention is necessary, carefully follow the steps to manually roll up the window.
Understanding the common reasons behind window malfunctions, such as regulator or motor issues, electrical problems, or obstructions, can help you prevent future occurrences and keep your BMW running smoothly.
