Is Your BMW’S Electronic Window Malfunctioning in Decatur?
Modern vehicles utilize electronic window systems instead of the crank style of the past. While these systems are much more convenient, they do tend to breakdown or fail at times. When your BMW experiences a power window problem, it can be a huge inconvenience as well as create additional issues. For example, a window that can not be rolled up allows rain or snow to come right into the vehicle. This may cause damage to the interior, upholstery, or leather as well as electrical components.
Windows that can not be closed also lead to safety issues for your BMW. Individuals have easier access to the inside by getting through an open window.
The driver’s side window is the most common window to break down due to its more frequent use. However, any window can become a victim of electronic trouble. Let’s take a closer look at electronic window malfunction or break down in your BMW.
5 Common Reasons for a Malfunctioning Power Window
Blown Fuse
Small fuses located in a fuse box inside the car can blow, causing the power to be shut off to the windows. Sometimes, it can be difficult to determine which fuse is involved and if it is truly blown.
Faulty Window Motor
There is a gear that is located at the end of the motor that connects to the window regulator. If the motor goes bad, there is no power to move the regulator. An overheated motor can cause problems that are intermittent instead of permanent. As the motor cools, the window will begin to work again. An experienced technician should check the wiring and the motor if overheating is suspected.
Faulty Window Switch
The power window button located on your door activates the switch. This component can wear out over time. It can also abruptly stop working all together.
Faulty Window Regulator
The regulator is a mechanism inside the door panel that allows the window to go up and down. Regulators can wear out over time for a number of reasons. Windows that are tinted or covered with stickers are thicker and harder on the mechanisms by causing extra resistance. This stress wears down the component quicker than normal. Cars that are out in the elements have windows that can become frozen in icy or snowy conditions. Frozen glass sticks to the frame and the regulator is not strong enough to break the ice free. This can lead to premature wear and tear as well.
Wiring Issues
It is uncommon for there to be problems with the wiring in the door that would cause a power window to malfunction. While it is rare, it can happen. DIY repairs or inexperienced mechanics may accidentally damage the wiring during servicing.
Other issues include a broken or dislocated regulator cable, residual effects from an accident, and other electronic hiccups. Some factors may be initially eliminated just by listening. If you can hear a humming sound when pressing the buttons but nothing happens, it rules outs a blown fuse or faulty switch.
How to Repair Power Windows in a BMW
If you have previous automotive experience, you may be able to DIY the necessary repairs for your power window issues. However, it is best to let a reputable and dependable technician diagnosis and repair the problem. Newer vehicle models have window components that vary greatly from those in older models. They are not constructed with screws, bolts, and nuts but riveted. This requires specific tools a trained mechanic would utilize.
