Volkswagen Jetta Blower Motor Not Working: [You Should Try This]

As a certified Volkswagen service technician, I have seen many cases of Volkswagen Jetta blower motors not working. This is a common problem that can be frustrating and inconvenient for drivers. The blower motor is responsible for circulating air through the vehicle’s ventilation system, so when it is not working properly, the driver may experience a number of problems, including:

Reduced airflow to the cabin
Difficulty defrosting the windshield
Increased interior humidity
Reduced visibility

In this troubleshooting guide, I will walk you through the steps to diagnose and potentially resolve the issue of a Volkswagen Jetta blower motor not working. I will also provide tips on how to prevent this problem from happening in the future.

Why Volkswagen Jetta Blower Motor Not Working

Blower Motor Fuse

The blower motor fuse is a 20 amp fuse located in the fuse box under the hood. If the fuse is blown, the blower motor will not work. To check the fuse, remove it from the fuse box and visually inspect it for damage. If the fuse is blown, replace it with a new one.

Blower Motor Relay

The blower motor relay is a small, cylindrical device located in the fuse box under the hood. If the relay is faulty, the blower motor will not work. To check the relay, remove it from the fuse box and test it with a multimeter. If the relay is bad, replace it with a new one.

Blower Motor Control Module

The blower motor control module is a small computer located under the dash. The control module sends a signal to the blower motor to turn on and off. If the control module is faulty, the blower motor will not work. To check the control module, connect a diagnostic scan tool to the vehicle and check for any codes related to the blower motor. If there are any codes, the control module may need to be replaced.

Blower Motor

The blower motor is a small electric motor that is responsible for blowing air through the vents. If the blower motor is faulty, it will not work. To check the blower motor, disconnect the electrical connector and turn on the blower motor switch. If the motor does not turn on, it is faulty and needs to be replaced.

How to Troubleshoot: Volkswagen Jetta Blower Motor Not Working

Overview

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
No heat or air conditioning
A loud noise coming from the dashboard

If you’re experiencing any of these problems, it’s likely that your blower motor is the culprit. To troubleshoot the issue, you’ll need to follow a few simple steps.

Step 1: Check the fuses

The first step is to check the fuses in your Volkswagen Jetta. The blower motor fuse is typically located in the fuse box under the hood. To check the fuse, you’ll need to remove the fuse box cover and locate the blower motor fuse. Once you’ve found the fuse, use a multimeter to check if it’s blown. If the fuse is blown, you’ll need to replace it with a new one.

Step 2: Check the blower motor relay

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, you’ll need to remove the relay from the fuse box and use a multimeter to check if it’s getting power. If the relay is not getting power, you’ll need to replace it with a new one.

Step 3: Check the blower motor

If the fuse and relay are both good, the next step is to check the blower motor itself. To check the blower motor, you’ll need to remove the blower motor from the dashboard. Once you’ve removed the blower motor, you can use a multimeter to check if it’s getting power. If the blower motor is not getting power, you’ll need to replace it with a new one.

Step 4: Inspect the blower motor wiring

If the blower motor is getting power, but it’s still not working, the next step is to inspect the blower motor wiring. The blower motor wiring is located in the dashboard. To inspect the wiring, you’ll need to remove the dashboard. Once you’ve removed the dashboard, you can inspect the wiring for any damage. If the wiring is damaged, you’ll need to repair or replace it.

Step 5: Take your Volkswagen Jetta to a qualified mechanic

If you’ve followed all of these steps and you’re still having problems, it’s time to take your Volkswagen Jetta to a qualified mechanic. A mechanic will be able to diagnose the problem and make the necessary repairs.
