By the end of this guide, you will be able to enjoy your Touareg’s heater again, without any interruptions.

So, Why 2004 Volkswagen Touareg Heater Blower Turns On And Off?

Here Are Some Reasons Mentioned Below

Blower Motor Failure

The blower motor is responsible for circulating air through the heater core and vents. If the blower motor fails, it will not be able to move air and the heater will not work.

Blower Motor Resistor Failure

The blower motor resistor controls the speed of the blower motor. If the resistor fails, the blower motor will not be able to operate at all or will only operate at one speed.

Blower Motor Switch Failure

The blower motor switch controls the power to the blower motor. If the switch fails, the blower motor will not be able to operate.

Fuse Failure

The blower motor fuse protects the blower motor from electrical overload. If the fuse blows, the blower motor will not be able to operate.

Wiring Problems

Wiring problems can cause the blower motor to operate intermittently or not at all. Wiring problems can be caused by damaged wires, loose connections, or corrosion.

FAQs: 2004 Volkswagen Touareg Heater Blower Turns On and Off

Why is my 2004 Volkswagen Touareg heater blower turning on and off?

There are a few possible reasons why your 2004 Volkswagen Touareg heater blower might be turning on and off. Here are a few of the most common causes:

A faulty blower motor: The blower motor is responsible for circulating air through the heater core and into the cabin. If the blower motor is faulty, it may not be able to provide enough airflow to keep the cabin warm.

A faulty blower motor resistor: The blower motor resistor controls the speed of the blower motor. If the resistor is faulty, it may not be able to provide the correct amount of power to the blower motor, which could cause it to turn on and off.

A faulty temperature control switch: The temperature control switch tells the blower motor how much air to circulate and at what temperature. If the switch is faulty, it may not be able to send the correct signal to the blower motor, which could cause it to turn on and off.

A faulty cabin air filter: The cabin air filter helps to keep dirt and debris out of the HVAC system. If the cabin air filter is dirty, it can restrict airflow and cause the blower motor to work harder than necessary, which could lead to it turning on and off.

How do I fix my 2004 Volkswagen Touareg heater blower?

To fix your 2004 Volkswagen Touareg heater blower, you will need to identify the cause of the problem. Once you have identified the cause, you can take the appropriate steps to fix it. Here are some tips for troubleshooting and fixing a faulty heater blower:

Check the blower motor: If you suspect that the blower motor is faulty, you can check it by disconnecting the electrical connector and turning the key to the On position. If you hear the blower motor running, it is likely working properly. If you do not hear the blower motor running, it is likely faulty and will need to be replaced.

Check the blower motor resistor: The blower motor resistor can be checked by disconnecting the electrical connector and using a multimeter to measure the resistance across the terminals. The resistance should be between 100 and 200 ohms. If the resistance is too high or low, the resistor is faulty and will need to be replaced.

Check the temperature control switch: The temperature control switch can be checked by disconnecting the electrical connector and using a multimeter to measure the resistance across the terminals. The resistance should change as you turn the temperature control knob. If the resistance does not change, the switch is faulty and will need to be replaced.

Check the cabin air filter: The cabin air filter can be checked by removing it from the housing and inspecting it for dirt and debris. If the filter is dirty, it should be replaced.

What are the symptoms of a faulty heater blower?

The symptoms of a faulty heater blower can include:

The blower motor does not work at all.
