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 with this model of van. But don’t worry, there is a simple fix. In this troubleshooting guide, I’ll walk you through the steps to diagnose and repair the problem. So you can get your cool air back on in no time.
Reasons Why 09 Volkswagen Routan Ac Not Working
Low Refrigerant Level
The most common reason for an A/C not working 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 A/C system. It’s responsible for compressing the refrigerant gas and sending it through the condenser, where it turns into a liquid. If the compressor is faulty, it won’t be able to compress the refrigerant gas, and the A/C won’t work.
Faulty Condenser
The condenser is responsible for cooling the refrigerant gas after it’s been compressed by the compressor. If the condenser is faulty, it won’t be able to cool the refrigerant gas, and the A/C won’t work.
Faulty Evaporator
The evaporator is responsible for turning the refrigerant gas back into a vapor. If the evaporator is faulty, it won’t be able to turn the refrigerant gas back into a vapor, and the A/C won’t work.
Faulty Control Unit
The control unit is responsible for sending signals to the compressor, condenser, and evaporator. If the control unit is faulty, it won’t be able to send the correct signals, and the A/C won’t 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 the hot summer months. However, if your AC isn’t working properly, it can be a real pain. There are a few different things that could be causing your AC to not work, and troubleshooting the problem can be a bit tricky. But don’t worry, we’re here to help. In this article, we’ll walk you through the steps of troubleshooting a 09 Volkswagen Routan AC that’s not working.
Step 1: Check the fuses
The first thing you should do is check the fuses for your AC. The fuses for the AC are located in the fuse box under the hood. There are two fuses that you need to check: the AC compressor fuse and the blower motor fuse.
To check the fuses, you’ll need a fuse tester. If either of the fuses is blown, you’ll need to replace it with a new fuse of the same amperage.
Step 2: Check the compressor clutch
The compressor clutch is a small electric motor that engages and disengages the AC compressor. If the compressor clutch is not working properly, it can prevent the AC from blowing cold air.
To check the compressor clutch, you’ll need to turn on the AC and listen for the compressor to engage. You should be able to hear a faint clicking sound. If you don’t hear the compressor engage, you’ll need to test the compressor clutch.
To test the compressor clutch, you’ll need a multimeter. First, disconnect the electrical connector from the compressor clutch. Then, set your multimeter to the AC voltage setting. Connect the positive lead of the multimeter to the wire that goes to the compressor clutch. Connect the negative lead of the multimeter to the ground.
Turn on the AC and start the engine. The multimeter should read around 12 volts. If the multimeter doesn’t read 12 volts, the compressor clutch is bad and will need to be replaced.
Step 3: Check the condenser
The condenser is a radiator-like device that cools the refrigerant gas. If the condenser is dirty or clogged, it can prevent the AC from blowing cold air.
To check the condenser, you’ll need to remove the air filter housing. Then, you’ll need to look at the condenser. If the condenser is dirty or clogged, you’ll need to clean it.
To clean the condenser, you can use a garden hose or a pressure washer. Be careful not to damage the condenser.
Step 4: Check the evaporator
The evaporator is a small radiator-like device that is located inside the passenger compartment. The evaporator cools the air that comes out of the vents. If the evaporator is dirty or clogged, it can prevent the AC from blowing cold air.
To check the evaporator, you’ll need to remove the glove box. Then, you’ll need to look at the evaporator. If the evaporator is dirty or clogged, you’ll need to clean it.
To clean the evaporator, you can use a vacuum cleaner or a can of compressed air. Be careful not to damage the evaporator.
Step 5: Check the refrigerant level
The refrigerant is a chemical that is used to cool the air in the AC system. If the refrigerant level is too low, it can prevent the AC from blowing cold air.
To check the refrigerant level, you’ll need a refrigerant manifold gauge. First, disconnect the high-pressure and low-pressure lines from the AC compressor. Then, connect the refrigerant manifold gauge to the high-pressure and low-pressure lines.
Turn on the AC and start the engine. The refrigerant manifold gauge should read around 25-35 psi on the high side and 20-25 psi on the low side. If the refrigerant level is too low, you’ll need to add refrigerant to the system.
Step 6: Inspect the AC lines
The AC lines are the hoses that carry the refrigerant gas through the AC system. If the AC lines are damaged or leaking, it can prevent the AC from blowing cold air.
To inspect the AC lines, you’ll need to look for any leaks. You can use a leak detector to help you find leaks. If you find any leaks, you’ll need to repair or replace the AC lines.
Why is my 2009 Volkswagen Routan AC not working?
There are a few possible reasons why your 2009 Volkswagen Routan AC may not be working. Here are a few of the most common causes:
A blown fuse: The first thing you should check is the fuse for the AC. If the fuse is blown, you will need to replace it.
A faulty compressor: The compressor is the heart of the AC system. If the compressor is not working, the AC will not be able to produce cold air.
A clogged condenser: The condenser is responsible for removing heat from the refrigerant. If the condenser is clogged, the AC will not be able to cool the air.
A leaky evaporator: The evaporator is responsible for transferring heat from the air inside the car to the refrigerant. If the evaporator is leaking, the AC will not be able to cool the air.
A faulty control head: The control head is responsible for sending signals to the AC compressor and other components. If the control head is faulty, the AC may not work properly.
How do I fix my 2009 Volkswagen Routan AC?
The fix for a 2009 Volkswagen Routan AC that is not working will depend on the cause of the problem. If the fuse is blown, you will need to replace it. If the compressor is faulty, you will need to have it replaced. If the condenser is clogged, you will need to have it cleaned or replaced. If the evaporator is leaking, you will need to have it repaired or replaced. If the control head is faulty, you will need to have it replaced.
How much does it cost to fix a 2009 Volkswagen Routan AC?
The cost of fixing a 2009 Volkswagen Routan AC will vary depending on the cause of the problem. The cost of replacing a fuse is typically around $5. The cost of replacing a compressor is typically around $500. The cost of cleaning or replacing a condenser is typically around $200. The cost of repairing or replacing an evaporator is typically around $300. The cost of replacing a control head is typically around $200.
How can I prevent my 2009 Volkswagen Routan AC from breaking down?
There are a few things you can do to help prevent your 2009 Volkswagen Routan AC from breaking down:
Keep the AC system clean: Make sure to clean the AC condenser and evaporator regularly. This will help to prevent them from becoming clogged and causing the AC to malfunction.
