Why Are Your Subaru Power Windows Not Working?

If you've noticed that your Subaru power windows are not working properly, you’re not alone. Power window issues are relatively common across all vehicle brands, and Subaru is no exception. No matter if the window won’t go up or down, or there’s a strange noise when you attempt to operate it, this issue can be both frustrating and concerning.

Understanding the potential causes of why your Subaru power windows are not working is the first step toward resolving the problem and getting your windows functioning correctly once again.

Common Causes of Subaru Power Windows Not Working

Power windows rely on several components working together to move the glass up and down smoothly. When one of these components fails or becomes damaged, the entire system can stop functioning.

Here are some of the most common causes of power window failure in Subaru vehicles:

• Electrical System Failures

One of the primary reasons for Subaru power windows not working is an issue with the electrical system. Power windows are controlled by a series of electrical switches, relays, and motors. A malfunction in any of these components can result in the window becoming inoperable.

The power window switch, typically located on the driver's side door panel, sends electrical signals to the window motor. If the switch is faulty or there’s a problem with the wiring, the signal may not reach the motor, preventing the window from moving.

In some cases, a blown fuse could be the culprit, as the fuse protects the electrical system from overloads. If the fuse blows, the power window will stop working.

• Motor and Regulator Issues

The power window motor is responsible for driving the window up and down. Over time, the motor may wear out or become damaged due to constant use. If the motor fails, the window will not respond to input from the switch. Additionally, the window regulator – a mechanism that helps guide and support the window as it moves – can also fail. A broken or misaligned regulator can prevent the window from operating properly.

If you hear a grinding noise when you try to raise or lower the window, it could be a sign that the motor or regulator has failed. A worn-out regulator can cause the window to move unevenly or become stuck in place.

• Window Tracks and Obstructions

Another cause for Subaru power windows not working is an obstruction in the window tracks. Dirt, debris, or even a piece of clothing caught in the tracks can prevent the window from moving smoothly. If there is a buildup of dirt or debris along the tracks, the window can become jammed and unable to move.

Sometimes, the issue may be as simple as a loose or detached window seal. This can cause the window to become misaligned, making it difficult to operate. It's important to inspect the window tracks for any visible obstructions or damage that might be interfering with the window's movement.

• Faulty Window Switches and Wiring

Power windows are controlled by electrical switches, and if one of these switches fails, it can prevent the window from functioning.

The most common failure occurs in the driver’s side window switch, as it is used more frequently. If the switch is unresponsive or doesn’t work when pressed, the issue could lie with the switch itself or the wiring connected to it.

Sometimes, wiring problems can cause the power window to malfunction. The wiring that connects the switch to the motor can become damaged due to age or exposure to the elements. In some cases, wiring may short-circuit, preventing the power window from responding to input from the switch.

Diagnosing and Repairing Power Window Issues

When your Subaru power windows are not working, it's essential to have the problem properly diagnosed and repaired by a professional technician. The technician will typically perform a series of tests to identify the root cause of the issue. They may check the window switch, motor, regulator, wiring, and electrical connections to pinpoint the problem.

If the issue is with the motor or regulator, these components may need to be replaced to restore full functionality to the window. If the wiring is damaged, repairs or replacements will be necessary to ensure the electrical signals reach the motor.

Preventing Future Power Window Issues

To avoid future issues with your Subaru power windows, it is important to have the vehicle’s window components regularly maintained at a Subaru service center.

Regularly clean the window tracks and lubricate the moving parts to reduce friction and wear. Be mindful of obstructions in the tracks and avoid forcing the window up or down if it becomes stuck. Keeping the electrical system in good working condition by inspecting fuses and wiring can also help prevent future problems.

Power window problems in your Subaru can stem from a variety of issues, including electrical failures, motor malfunctions, and obstructions in the window tracks. If your power windows are not working, it's important to have the system professionally diagnosed to pinpoint the cause and make necessary repairs.
