What You'll Learn
Check the fuses
If you are experiencing issues with the electric windows of your Skoda Fabia, it is recommended to check the fuses as a potential solution. Fuse issues can cause the windows to malfunction or stop working entirely.
First, locate the fuse box inside your Skoda Fabia. The interior fuse box is typically located on the driver's side of the vehicle, often under the steering column or near the floor pedal. It may be housed behind a plastic cover that can be easily removed for access.
Once you have located the interior fuse box, identify the specific fuses related to the electric windows. In the Skoda Fabia, the driver's side and passenger side windows are usually protected by separate fuses, namely fuses 51 and 2, respectively. These fuse numbers may vary depending on the specific model and year of your Skoda Fabia, so it is advisable to refer to your owner's manual or seek guidance from a Skoda technician.
Carefully examine the condition of the fuses. Fuses are designed to protect the electrical system by burning out when there is a power surge or overload. A blown fuse will typically appear damaged or melted, with a broken wire inside. If you suspect that a fuse is blown, use a fuse puller or a pair of tweezers to carefully remove it for closer inspection.
If the fuses for the electric windows are indeed blown, they will need to be replaced with new ones of the same amperage and type. Ensure that you handle fuses with care and avoid touching the metal strips directly, as oil from your skin can affect their performance. Refer to your Skoda Fabia's manual for the correct fuse type and rating, and always keep spare fuses in your vehicle for emergencies.
In addition to the interior fuse box, it is recommended to check the engine bay fuse box as well. Fuse 2 in this box, also known as the fusible link, covers the interior of the car. A blown fuse in this box could also be the cause of electric window issues.

Check the wiring
If the electric windows on your Skoda Fabia are not working, there could be a fault in the wiring. Before attempting any repairs, make sure you have the necessary knowledge and equipment to work with automotive electrical systems safely.
First, check the wiring diagram for your vehicle. This will help you locate the relevant components and connections. If you don't have access to a wiring diagram, you can try searching for one online or consulting a repair manual specific to your vehicle.
Next, locate the door pillar wiring grommets and inspect the wires for any breaks or damage. Make sure to check both sides of the vehicle, as issues with the wiring on one side could affect the windows on both doors. If you find any damaged wires, they will need to be repaired or replaced.
Another potential issue could be with the LIN (Local Interconnect Network) signal. The driver's window motor is the LIN master, and a fault with it can prevent the passenger window from working. Use a scope to check for a LIN signal at the driver's door window motor/module. If there is no signal, the issue may lie with the switch or the wiring, or the motor itself may need to be replaced.
Additionally, check the fuses for the windows. The front windows are covered by separate fuses (fuses 51 and 2 in the interior fuse box). It is unlikely that both fuses would be blown, but it is worth checking. Also, check fuse 2 in the engine bay fuse box, as it covers the interior of the car.
If you cannot identify any issues with the wiring or fuses, the problem may lie with the Comfort Module, which controls the windows and other systems in the car. This module may have failed or been damaged by an electrical short or shunt. In this case, you will need to have the car plugged into a Skoda diagnostic machine to identify and rectify the fault.

Check the window motors
If your Skoda Fabia's electric windows aren't working, it could be due to a faulty window motor. The window motor is the component that drives the mechanism that opens and closes the windows. If this motor burns out, it will need to be replaced.
To check if the window motor is faulty, you can start by examining the driver's window motor, as it is the LIN master and will prevent the passenger window from working if it fails. Use a scope to check for a LIN signal at the driver's motor. If there is no signal, it is likely that the driver's window motor requires replacement.
You can also try to diagnose the issue by observing the behaviour of the windows. If both front electric windows are not working with either switch, it could indicate a common fault or a problem with the wiring. Check the door pillar wiring grommets for any breaks in the wires. If the wiring appears intact, the issue may lie with the window motors.
In some cases, the fault may lie with the master LIN in the driver's window motor. If this is not present, the passenger window motor will not function. Therefore, it is important to check the LIN at the driver's motor to determine if it is functioning correctly.
If you suspect that the window motor needs to be replaced, it is recommended to consult a professional or seek advice from a Skoda specialist to ensure the correct diagnosis and repair.

Check the central locking
If you are experiencing issues with the electric windows in your Skoda Fabia, it is important to check the central locking system as they may be interconnected. There have been reports of central locking acting erratically alongside electric window malfunctions. For example, the doors would randomly lock or unlock when opened or closed, or there would be issues with double locking.
To troubleshoot, start by checking the fuses. The two windows are covered by separate fuses (fuses 51 and 2 in the interior fuse box). It is unlikely that both fuses would blow simultaneously, but it is worth checking. Next, inspect fuse 2 in the engine bay fuse box, as this fuseable link covers the interior of the car.
If the fuses are intact, the issue may lie with the Comfort Module, which has overall control of the systems in question. This module may have failed or been damaged by an electrical short or shunt. In this case, you will need to have the car plugged into a Skoda diagnostic machine to identify and rectify the fault.
In some cases, the problem may be attributed to the lock button inside the door on the driver's side. It is recommended to explore this possibility by referring to relevant videos or seeking advice from a Skoda technician.
It is important to note that attempting to repair or replace components without proper knowledge or guidance can be dangerous and may void any warranties or insurance policies associated with your vehicle. Always consult a qualified technician or seek advice from official Skoda sources before attempting any repairs or modifications.

Check the battery
If your electric windows are not working, it is a good idea to check the battery. First, check the fuses. If the fuses are fine, the next step is to check the LIN signal at the driver's door. If there is no LIN signal, the issue is likely with the driver's window motor, which is the LIN master and will prevent the passenger window from working if it fails. You can try to replace the driver's window motor to see if that rectifies the fault.
To check the battery, you will need to locate the fuse box. The fuse box is typically located in the engine bay or the interior of the car. Once you have located the fuse box, look for the fuses related to the electric windows. In some Skoda Fabia models, the windows are covered by separate fuses (fuses 51 and 2 in the interior fuse box). There may also be a fuse in the engine bay fuse box that covers the interior of the car (fuse 2).
After locating the relevant fuses, use a fuse tester or a multimeter to check if they are blown. If the fuses are blown, replace them with new ones of the same amperage. If the fuses are fine, move on to checking the LIN signal as described earlier.
It is also worth noting that some issues with electric windows may be related to the wiring. Check the door pillar wiring grommets for any breaks in the wires. If there are no issues with the wiring, it is likely that the fault lies with the window motor or module. In this case, you may need to consult a professional for further diagnosis and repair.
By following these steps and checking the battery, fuses, and wiring, you can narrow down the potential causes of electric window malfunction in your Skoda Fabia and take appropriate action to resolve the issue.
