Main causes of power window problems
When it comes to the car window, knowing what caused it to malfunction is essential for determining the right solution. Here are some of the possible reasons you should remember for safety:
Blown fuse
The fuse in your car protects the electrical components from overloading. If the power window fuse blows and the circuit breaks, the windows stop functioning. Although replacing the fuse can repair the power window, it is essential to determine the reason it failed in the first place. It will help prevent such problems in the future.
Bad window switch
The switches you use to roll the window up and down can wear out at any time. They may be unable to send the correct signal to the motor, leaving the window stuck at the same position.
Worn-out window motor or regulator
A motor helps move the window up and down, but if it doesn’t engage with the regulator when you try to push the button up and down. Another indicator of motor failure is that the window rolls up and down more slowly than expected.
Damaged wiring or loose connections
The power windows depend on the wiring to connect the window motor to the power switch. However, these wires pinch, fray, or break down over time. This damage stops the electrical signals from reaching the motor. It leads to unresponsive windows.
Window track misalignment or obstruction
Sometimes, it is not an electrical but a mechanical problem that prevents the power window from operating properly. When dirt, debris, and dust accumulate in the window track, it creates a resistance that prevents the motor from functioning properly. You may notice the windows struggling to function or making uneven noises.
Moisture or corrosion in electrical components
The seals around the window edges expand in the summer, leading to increased resistance. Additionally, moisture seeps in, resulting in corrosion and malfunction. It requires regular maintenance and weatherstripping to keep your car’s power windows running.
Common signs your power windows are failing
How do you know that your car’s power window isn’t functioning or can soon stop working?
Here are the signs to follow:
The window doesn’t move up or down
The window glass gets stuck between or doesn’t move from its place. It is a clear sign that the window glass is worn out and requires repair or replacement.
Slow or jerky window movement
Are you noticing that the window is rolling more slowly than normal or is jerking during movement? It might mean the window motor is the problem. Today’s power window is designed to operate at a specific speed to prevent damage to its components. However, once the motor starts to fail, the fuse can soon blow, and it will no longer supply any power.
Clicking sound when pressing the switch
You can tell the window motor is failing by the clicking sound it makes. At times, the reason may be dust settling between the motor and the window. However, if this problem persists, the motor must work harder, causing increased stress and wear. In the long run, the stuck dust not only hampers the power window performance but also scratches it.
One or more windows are not responding
You are pressing the switch, but the window isn’t functioning? It is definitely a sign to check the fuses. If all the fuses are working fine, your next step is to check the motor. In either case, your car’s power windows require repair.
Unusual noises from the door panel
Not only the power window, but even the door panel can alert you that something is wrong. If you hear any rattling or clunking sounds, it may indicate that the motor is damaged or becoming loose. The ultimate consequences will be borne by the windows.
The window is stuck partially open
If the power window gets stuck when moving up or down, it is time to get it fixed. At times, you may also experience the windows working for some time and then failing again later.
How to fix or prevent power window problems
Power windows are an essential component to make your drive comfortable, relaxing, and safe. But when it fails, you should know what to look for and how to prevent it in the future. Here are some things to remember:
Check and replace blown fuses or relays
The first step is to check if the fuse or relay for the power window has blown. Locate the fuse and remove it with the help of a pair of pliers or a puller. Afterwards, insert the replacement fuse and fit it properly so it doesn’t move. Test the power windows to ensure they are functioning properly.
Test and clean window switches
If the problem is with the power window switches, clean them of dirt and debris and try to see if they work. If they still don’t perform, replace the damaged switch with a new one. Your best approach is to let a car mechanic use their expertise and install a new window switch.
Inspect wiring for damage or loose connections
Sometimes the problem lies in the power window wiring. You can inspect it to locate the problem. The chances are that the wires are damaged or aren’t properly connected. You can contact a professional mechanic for assistance in this situation.
Lubricate or realign window tracks
Try cleaning the window tracks when dirt or debris is stuck inside. You can apply a lubricant or realign them to minimise friction and prevent the motor from wearing off.
Replace a faulty window motor or regulator
You have diagnosed that the window motor or regulator is the problem. You can replace it yourself if you are familiar with the tools and techniques. However, it is advisable to consult a mechanic to get them repaired or a new motor installed.
Keep electrical components dry and clean
Damp or dirty electrical components can quickly hamper their functioning. To ensure that your power window operates properly, it's essential to maintain and care for it regularly.
Bottom line
Power windows are a convenient feature, but when they stop working, it can be frustrating. Often, issues are caused by blown fuses, faulty motors, switches, or wiring problems. Regular maintenance, like cleaning tracks, checking switches, and keeping electrical components dry, can help prevent most problems.
