As a certified Volkswagen service technician, I have seen firsthand the frustration and inconvenience that a malfunctioning blower motor can cause for Volkswagen Jetta owners. Not only is it a safety hazard, but it can also make driving in hot weather extremely uncomfortable. That’s why I’ve created this troubleshooting guide to help you quickly diagnose and resolve the issue.

This guide will walk you through the steps necessary to identify the cause of the problem and take the necessary steps to fix it. By the end of this guide, you’ll be able to get your Jetta’s blower motor working again so you can enjoy comfortable rides all summer long.

Why Volkswagen Jetta Blower Motor Not Working

Blower Motor Fuse

The blower motor fuse is a 15-amp fuse located in the Volkswagen Jetta’s fuse box. If the fuse is blown, the blower motor will not work. To check the fuse, remove it from the fuse box and use a multimeter to check for continuity. If the fuse is blown, replace it with a new one.

Blower Motor Relay

The blower motor relay is a small, cylindrical device that is located in the Volkswagen Jetta’s fuse box. The relay receives power from the fuse box and sends it to the blower motor. If the relay is faulty, the blower motor will not work. To check the relay, remove it from the fuse box and use a multimeter to check for continuity. If the relay is faulty, replace it with a new one.

Blower Motor Control Module

The blower motor control module (BCM) is a computer that controls the operation of the blower motor. The BCM receives inputs from the climate control system and sends signals to the blower motor to control its speed. If the BCM is faulty, the blower motor will not work. To check the BCM, you will need to use a Volkswagen diagnostic tool.

Blower Motor

The blower motor is a electric motor that is responsible for blowing air through the vents in the Volkswagen Jetta’s interior. If the blower motor is faulty, it will not work. To check the blower motor, you will need to remove it from the vehicle and test it with a multimeter. If the blower motor is faulty, replace it with a new one.

How to Troubleshoot: Volkswagen Jetta Blower Motor Not Working

The blower motor in your Volkswagen Jetta is responsible for circulating air through the cabin. If the blower motor is not working, you may experience a number of problems, including:

Reduced airflow to the vents
Difficulty defogging the windshield
Increased interior temperatures

If you are experiencing any of these problems, it is important to troubleshoot the blower motor to determine the cause of the issue.

Troubleshooting the Blower Motor

The first step in troubleshooting the blower motor is to check the fuses. The blower motor fuse is located in the fuse box under the hood. To check the fuse, remove the fuse from the fuse box and visually inspect it for damage. If the fuse is blown, replace it with a new fuse of the same amperage.

If the fuse is not blown, the next step is to check the blower motor relay. The blower motor relay is located in the fuse box under the hood. To check the relay, remove the relay from the fuse box and use a multimeter to test for continuity. If the relay is not functioning properly, replace it with a new relay.

If the fuse and relay are both functioning properly, the next step is to check the blower motor itself. To check the blower motor, disconnect the electrical connector from the blower motor and use a multimeter to test for continuity between the two terminals on the connector. If there is no continuity, the blower motor is defective and needs to be replaced.

Replacing the Blower Motor

Replacing the blower motor in a Volkswagen Jetta is a relatively simple task that can be completed in about an hour. To replace the blower motor, you will need:

A new blower motor
A Phillips head screwdriver
A Torx T25 screwdriver

1. Locate the blower motor. The blower motor is located in the passenger compartment, behind the glove box.
2. Remove the glove box. To remove the glove box, open the glove box and locate the two Phillips head screws on the bottom of the glove box. Remove the screws and carefully lift up on the glove box to remove it.
3. Disconnect the electrical connector from the blower motor. The electrical connector for the blower motor is located on the back of the blower motor. Use a Phillips head screwdriver to disconnect the electrical connector.
4. Remove the two Torx T25 screws that secure the blower motor to the housing. The two Torx T25 screws that secure the blower motor to the housing are located on the top and bottom of the blower motor. Use a Torx T25 screwdriver to remove the screws.
5. Remove the blower motor. Carefully lift up on the blower motor and remove it from the housing.
6. Install the new blower motor. Align the new blower motor with the housing and carefully lower it into place. Secure the blower motor to the housing with the two Torx T25 screws.
7. Reconnect the electrical connector to the blower motor. Reconnect the electrical connector to the blower motor.
8. Install the glove box. Carefully lower the glove box into place and secure it with the two Phillips head screws.

Once the blower motor has been replaced, test the blower motor to make sure it is working properly. If the blower motor is not working properly, repeat the steps above to troubleshoot the problem.
