09 Volkswagen Routan Ac Not Working [Step-By-Step Fixes]

Do you own a 2009 Volkswagen Routan and your AC isn’t working You’re not alone. This is a common problem that can be frustrating and inconvenient. But don’t worry, there is a solution. In this troubleshooting guide, I’ll walk you through the steps to diagnose and fix the problem. So whether you’re a DIYer or you’re taking your car to a mechanic, this guide will help you get your AC up and running again.

Why 09 Volkswagen Routan Ac Not Working

Low Refrigerant Level

The most common cause of an AC not working in a Volkswagen Routan is a low refrigerant level. This can be caused by a leak in the system, a faulty compressor, or a problem with the condenser or evaporator.

Faulty Compressor

The compressor is the heart of the AC system. If it fails, the AC will not work. Compressors can fail for a variety of reasons, including electrical problems, mechanical problems, or contamination.

Faulty Condenser or Evaporator

The condenser and evaporator are the two main components of the AC system. If either of these components fails, the AC will not work. Condensers can fail due to corrosion or damage, while evaporators can fail due to leaks or blockages.

Faulty Control Module

The control module is the brain of the AC system. It controls the compressor, condenser, and evaporator, and sends signals to the dashboard display. If the control module fails, the AC will not work.

How to Troubleshoot: 09 Volkswagen Routan AC Not Working

The air conditioner in your Volkswagen Routan is an important part of keeping you cool and comfortable during hot weather. If your AC isn’t working properly, it can be a major inconvenience. Fortunately, there are a few things you can check to troubleshoot the problem and get your AC back up and running.

Possible Causes

There are a number of things that could cause your Volkswagen Routan’s AC to stop working. Some of the most common causes include:

A blown fuse
A faulty compressor
A leak in the refrigerant lines
A dirty or clogged air filter
A malfunctioning control panel

Troubleshooting Steps

To troubleshoot the problem with your Volkswagen Routan’s AC, you’ll need to start by inspecting the system for any obvious signs of damage. Look for leaks in the refrigerant lines, a dirty or clogged air filter, or a malfunctioning control panel. If you don’t see any obvious problems, you can try the following steps:

1. Check the fuses. The AC compressor is powered by a fuse, so if the fuse is blown, the compressor won’t be able to turn on. To check the fuse, locate the fuse box in your Volkswagen Routan’s engine compartment. The fuse box is usually located near the battery. Once you’ve located the fuse box, look for a fuse that’s labeled AC or A/C. If the fuse is blown, replace it with a new fuse that has the same amperage rating.
2. Test the compressor. To test the compressor, you’ll need a voltmeter. Connect the voltmeter to the battery terminals. Start the engine and turn on the AC. The compressor should start to run and the voltmeter should read between 12 and 14 volts. If the compressor doesn’t start to run or the voltmeter doesn’t read between 12 and 14 volts, the compressor is faulty and will need to be replaced.
3. Check the refrigerant lines. The refrigerant lines carry refrigerant from the compressor to the evaporator. If there’s a leak in the refrigerant lines, the AC won’t be able to cool the air. To check for leaks, you can use a leak detector. A leak detector is a device that emits a gas that will react with refrigerant. If there’s a leak in the refrigerant lines, the leak detector will start to glow.
4. Clean the air filter. The air filter helps to keep dirt and debris from entering the AC system. If the air filter is dirty or clogged, it can restrict airflow and cause the AC to work less efficiently. To clean the air filter, remove it from the housing and rinse it with warm water. Allow the air filter to dry completely before reinstalling it.
5. Check the control panel. The control panel is responsible for sending signals to the compressor and other components of the AC system. If the control panel is malfunctioning, it can prevent the AC from working properly. To check the control panel, you’ll need to use a diagnostic tool. A diagnostic tool is a device that can read the codes stored in the car’s computer. If there are any codes stored, they can help you identify the problem with the control panel.

Conclusion

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

FAQs: 09 Volkswagen Routan AC Not Working

Why is my 09 Volkswagen Routan AC not working?

There are a few possible reasons why your 09 Volkswagen Routan AC may not be working. Here are some of the most common:

The AC compressor is not working: This is the most common cause of an AC problem. The AC compressor is responsible for compressing the refrigerant gas, which then circulates through the evaporator and condenser coils to cool the air inside the cabin. If the compressor is not working, the AC will not be able to produce cold air.

The refrigerant gas is low: The refrigerant gas is what actually cools the air inside the cabin. If the refrigerant gas level is too low, the AC will not be able to produce cold air.

The condenser coils are dirty: The condenser coils are located in the front of the vehicle and are responsible for cooling the refrigerant gas. If the condenser coils are dirty, they will not be able to effectively cool the refrigerant gas, which will result in decreased AC performance.

The evaporator coils are dirty: The evaporator coils are located in the dashboard and are responsible for evaporating the refrigerant gas. If the evaporator coils are dirty, they will not be able to effectively evaporate the refrigerant gas, which will result in decreased AC performance.

The AC control unit is defective: The AC control unit is responsible for sending signals to the AC compressor, evaporator, and condenser to control the temperature of the air inside the cabin. If the AC control unit is defective, it may not be sending the correct signals, which will result in decreased AC performance.

How do I fix my 09 Volkswagen Routan AC?

The first step is to determine what is causing the AC problem. Once you have determined the cause of the problem, you can then take the appropriate steps to fix it. Here are some of the most common AC repairs:

Replace the AC compressor: If the AC compressor is not working, it will need to be replaced. This is a relatively straightforward repair that can be completed by a qualified mechanic.

Refill the refrigerant gas: If the refrigerant gas level is low, it can be refilled. This is a relatively simple repair that can be completed by a qualified mechanic.

Clean the condenser coils: If the condenser coils are dirty, they can be cleaned. This can be done by using a garden hose or a pressure washer.

Clean the evaporator coils: If the evaporator coils are dirty, they can be cleaned. This can be done by using a vacuum cleaner or a brush.

Replace the AC control unit: If the AC control unit is defective, it will need to be replaced. This is a relatively complex repair that should only be performed by a qualified mechanic.

How much does it cost to fix a 09 Volkswagen Routan AC?

The cost of fixing a 09 Volkswagen Routan AC will vary depending on the cause of the problem. The cost of replacing the AC compressor, for example, will be significantly higher than the cost of refilling the refrigerant gas. Here are some of the average costs of common AC repairs:

Replace the AC compressor: $500-$1,000

Refill the refrigerant gas: $100-$200

Clean the condenser coils: $50-$100

Clean the evaporator coils: $50-$100

Replace the AC control unit: $300-$500

How can I prevent my 09 Volkswagen Routan AC from breaking down?
