Let us know in detail the reasons for the power window not working so that you can solve this problem properly.

1. Power Window Fuse Blown

Vehicles often have separate fuses for different power supplies for each type of electronic function. So that the wires and electrical components can be kept safe in case of jam in case of emergency or short circuit in the wiring.

What To Do To Fix It – If there is a fault in any electrical component or associated wiring, the first thing that happens is that the electrical fuse blows and this permanently cuts off the power supply. The most common cause of power window not working is a blown fuse, which should be checked first and replaced with a new one if the fuse is bad.

2. Damaged Power Window Wiring

The main component in the functioning of a power window is the electric motor and this electric motor varies for each window, along with the wiring used to supply power. Sometimes the power cords of power windows can get damaged or broken. It is often seen that rats enter a vehicle, which can gnaw or cut any electrical wire installed in the vehicle.

What To Do To Fix It – The power window motor may not operate due to the power wires being damaged or cut. Therefore, whenever a power window is not working, you should check the wiring after checking the fuse. If you find any cut or damaged wiring, repair or replace the wiring.

3. Defective Power Window Regulators

window regulator

The regulator in a power window is the mechanism part that moves the window glass up or down. But many times, due to the vehicle being parked for a long time, the regulator gets broken due to rust or the regulator gets jammed.

Because of which, the power windows do not operate. In this case, the electric motor works, but a bad or broken regulator is unable to raise or lower the window. Therefore, a broken or faulty regulator can also be one of the main reasons for power windows not working. So, if the power window does not work, be sure to check the regulator. Note, power windows have separate regulators for each window.

4. Bad Power Window Control Module

The window control module is installed to operate and control the power windows, which supplies power to the power window’s electric motor. But sometimes the power window control module malfunctions, because the power supply does not reach the electric motor and the power window motor does not run. So, sometimes a bad control module can also be a reason for the power windows not working.

So, if the power window is not working, be sure to check the control module and get it repaired or replaced if the power window control module is bad.

5. Faulty Power Window Control Switch

Often, you will notice that modern cars have a control panel on the driver’s window to raise or lower the power windows and the rest of the second window has a single switch to control the power windows.

Thereby the power windows are operated upwards or downwards. But sometimes, due to some reason, some kind of fault occurs in the power window control switch panel or single switch. Due to this, the power windows do not work or it starts running stuck. One of the main reasons why power windows may not work is a faulty control switch panel.

In case of such a problem, check the control switch panel of the power windows. If the control switch panel or single switch of the power windows of your vehicle is defective, then you should get it repaired or replaced with a new one.

6. Extreme Cold Weather

The effect of weather can also be the reason for power windows not working. Typically, the power windows of cars or other vehicles stop working in very cold areas. In areas where the temperature reaches zero in winter and snow starts freezing or falling, the power windows of cars start freezing or the car gets completely covered with ice.

Due to this, the motor of the power window runs, but due to the regulator being jammed, the regulator of the power window does not run. One reason power windows may not work is because the weather is too cold.

7. Faulty Remote Lock System

In modern cars or other vehicles, the function of power windows is attached to the center locking system. as the driver gets out of the car. The driver can then operate the power windows from the outside with the center lock remote.

But sometimes, due to the fault in the center lock model, the function of the power windows also gets affected. Hence, the power windows do not work due to the defective center lock model.

8. Power Window Relay Malfunction

Electric motors are fitted to each window to operate the power windows. A power relay is installed to provide adequate power supply to the electric motor of all these windows. So that the power cannot be less or more and the power window motor can work properly.

The power relay also protects the electric motor from overheating. But sometimes the power supply to the electric motor of the power windows stops due to a faulty power relay. Due to this, the power window does not work.

9. Discharge or Damage Battery

Power windows in vehicles are powered by 12 V DC current from the battery. But sometimes the power window is unable to work due to the battery being weak or discharged or the power window is going up or down very slowly, caused by the battery Thus, the main reason for the power windows not working can be a weak or discharged battery. Also, when the battery is completely dead, the power windows will not respond in any way. And no light indication will be lit in the cluster meter of the vehicle.
