Power windows, also known as electric car windows, are a real convenience compared to roll up car windows. With the press of a button, you can easily lower or raise the driver and passenger-side windows. At least, that's how it goes if your windows are in proper working condition. Car windows that won't move up or down can be frustrating, especially in high and low temperatures. In the event the window is stuck open, it can also leave you concerned about drive and passenger safety and worried about any valuables you have inside the car. Suffice to say, no one likes finding out that one or more of the power windows is stuck.

And that might leave you wondering: why do power windows fail?

Enter today's topic of discussion.

Here are some of the causes behind malfunctioning power windows:

Malfunctioning Window Regulator: One of the primary reasons for an electric car window to fail is due to a malfunctioning window regulator. This is the mechanism that controls the up and down motion of the window. The power window regulator consists of gears, linkages, and support parts that can wear down or break over time, especially with frequent use. Because the regulator is located within the door panel, it is also exposed to temperature fluctuations and debris. This exposure makes it vulnerable to corrosion and clogs. If the window is misaligned or obstructed, it can also place strain on the regulator's motor and lead to burnout. An auto repair shop that works on power windows, such as Deltona Discount Tires, can replace or repair the window regulator.

Motor Failure: Another reason power windows fail is due to the electric motor burning out or becoming overworked. This can happen due to several reasons, such as the internal components of the window switch wearing out. This is a natural result of repeated use and can also lead to failure of the motor. Another reason is mechanical failure from force. If the window experiences strain, such as trying to move it when it's frozen shut, the gears can strip or the clutch mechanism inside the motor can fail. Bad wiring or a faulty connection can prevent the motor from receiving the power it needs to operate while water damage can cause short circuits or corrosion.

Frozen Windows: A car's electric windows can become stuck if temperatures are low enough to freeze them. Attempting to force the windows to move can cause more damage. Power windows freeze due to moisture on the glass or within the window's components, such as the run channels or belt moldings. This moisture can turn into ice in winter, effectively sealing the window shut. When you attempt to operate a frozen window, the motor tries to move the glass, which can't move because it i stuck. This puts strain on the motor and the gears within it. Repeated attempts to force the window down can lead to gear damage or even burn out the motor due to the excessive load, resulting in repairs. To prevent this, it's important to clear any ice build-up that's accessible before trying to use the power windows.

Electrical Wiring Issues: Bad wiring or a faulty connection can prevent the motor from receiving the power it needs to operate. This can be due to frayed wires, corrosion, or loose connections. If the motor doesn't receive power due to a blown fuse or a short circuit, the window will not operate. Additionally, corroded wires or poor electrical contacts can cause intermittent window function or complete failure. A broken motor, cable pulley, or window regulator can also result in non-functional power windows, as these components rely on electrical signals to function.

Is It Possible to Prevent Issues with Power Car Windows?

Since you can't see the inner workings of the power windows in plain view, it can be hard to know when they need service until something stops working. If the reason that the windows are stuck is due to frigid temperatures, however, make sure you don't force the issue. You can also be cognizant of how frequently you use the windows. Overuse can cause them to wear out sooner than later.

You can always take a closer look at the inner workings of your vehicle, inspect the window tracks and other components, and add lubrication. If you are concerned about your car windows, a mechanic can also take a look for you.
