Why Volkswagen Polo Electric Windows Not Working

Bad door switch

The door switch is a small, electrical component that tells the car when to open or close the window. If the switch is faulty, it can prevent the window from working properly.

Bad window motor

The window motor is the component that actually moves the window up and down. If the motor is faulty, it will not be able to move the window, even if the switch is working properly.

Bad window regulator

The window regulator is the component that holds the window in place and allows it to move up and down. If the regulator is faulty, it can prevent the window from working properly.

Wiring problem

The window motor and regulator are connected to the car’s electrical system by a series of wires. If there is a problem with the wiring, it can prevent the window from working properly.

Faulty computer

In some Volkswagen Polo models, the window operation is controlled by a computer. If the computer is faulty, it can prevent the windows from working properly.

How to Troubleshoot: Volkswagen Polo Electric Windows Not Working

Your Volkswagen Polo’s electric windows are a convenient feature, but they can be a pain when they stop working. There are a few things you can check to troubleshoot the problem and get your windows back in working order.

Step 1: Check the fuses

The first thing you should do is check the fuses for the electric windows. The fuses are located in the fuse box, which is usually located under the dashboard. There will be a diagram of the fuse box in your car’s owner’s manual.

To check the fuses, you will need a fuse tester. You can purchase a fuse tester at most auto parts stores. Once you have the fuse tester, remove the fuses for the electric windows from the fuse box. Insert the fuse tester into the fuse slots and check for continuity. If the fuse is blown, replace it with a new fuse of the same amperage.

Step 2: Check the wiring

If the fuses are good, the next thing you should check is the wiring for the electric windows. The wiring is located in the door jambs. To check the wiring, you will need a voltmeter. You can purchase a voltmeter at most auto parts stores.

Once you have the voltmeter, turn on the ignition and open one of the doors. Disconnect the connector from the motor for the window you are testing. Connect the positive lead of the voltmeter to the connector and the negative lead to the ground.

If you have power at the connector, the problem is with the motor. If you do not have power at the connector, the problem is with the wiring.

Step 3: Check the motor

If the wiring is good, the next thing you should check is the motor. The motor is located in the door jamb. To check the motor, you will need a multimeter. You can purchase a multimeter at most auto parts stores.

Once you have the multimeter, disconnect the connector from the motor. Connect the positive lead of the multimeter to the connector and the negative lead to the ground.

Turn on the ignition and operate the window switch. The motor should make a humming sound. If the motor does not make a humming sound, the motor is bad and needs to be replaced.

Step 4: Check the regulator

If the motor is good, the next thing you should check is the regulator. The regulator is located in the door jamb. To check the regulator, you will need a multimeter. You can purchase a multimeter at most auto parts stores.

Once you have the multimeter, disconnect the connector from the regulator. Connect the positive lead of the multimeter to the connector and the negative lead to the ground.

Turn on the ignition and operate the window switch. The regulator should make a clicking sound. If the regulator does not make a clicking sound, the regulator is bad and needs to be replaced.

Conclusion

These are the steps you can take to troubleshoot a Volkswagen Polo electric window that is not working. If you are not comfortable working on your car, you can take it to a qualified mechanic.
