Why 2012 Volkswagen Jetta Ac Not Working

Low Refrigerant Level

The most common reason for a 2012 Volkswagen Jetta AC not working is low refrigerant level. The AC system uses a refrigerant gas to cool the air inside the car. If the refrigerant level is low, the AC compressor will not be able to generate enough cold air.

Faulty AC Compressor

Another common cause of a 2012 Volkswagen Jetta AC not working is a faulty AC compressor. The AC compressor is the heart of the AC system, and if it is not working properly, the AC will not be able to cool the air inside the car.

Faulty AC Condenser

The AC condenser is responsible for removing heat from the refrigerant gas. If the condenser is faulty, it will not be able to remove heat from the refrigerant gas, and the AC will not be able to cool the air inside the car.

Faulty AC Expansion Valve

The AC expansion valve is responsible for regulating the flow of refrigerant gas into the evaporator. If the expansion valve is faulty, it will not be able to regulate the flow of refrigerant gas, and the AC will not be able to cool the air inside the car.

Faulty AC Evaporator

The AC evaporator is responsible for cooling the air inside the car. If the evaporator is faulty, it will not be able to cool the air inside the car.

Faulty AC Control Unit

The AC control unit is responsible for sending signals to the various components of the AC system. If the AC control unit is faulty, it will not be able to send signals to the various components of the AC system, and the AC will not be able to cool the air inside the car.

How to Troubleshoot: 2012 Volkswagen Jetta AC Not Working

Your 2012 Volkswagen Jetta’s air conditioner is not working properly, and you’re not sure what to do. You’ve tried turning it on and off, but it’s still not blowing cold air. In this article, we’ll walk you through the steps to troubleshoot the problem and get your AC up and running again.

Step 1: Check the fuses

The first thing you should do is check the fuses for the AC system. The fuses are located in the fuse box under the hood. There are two fuses that you need to check: the AC fuse and the blower motor fuse.

To check the fuses, use a voltmeter to test for continuity. If the fuse is blown, it will have no continuity. You can replace the fuse with a new one that has the same amperage rating.

Step 2: Check the compressor clutch

The compressor clutch is a small electric motor that engages the compressor. When the compressor clutch is engaged, it turns the compressor, which then compresses the refrigerant gas. This compressed gas is then sent through the evaporator, where it cools the air that is blown into the cabin.

To check the compressor clutch, you’ll need to use a multimeter to test for voltage. First, turn on the AC and set the temperature to the coldest setting. Then, turn on the headlights. This will put a load on the electrical system, which will make it easier to see if there is a problem with the compressor clutch.

With the headlights on, use the multimeter to test for voltage at the compressor clutch connector. If there is no voltage, the compressor clutch is not getting power. This could be due to a problem with the wiring, the control module, or the compressor clutch itself.

Step 3: Check the refrigerant level

The next thing you should check is the refrigerant level. The refrigerant is a type of gas that is used to cool the air in the cabin. If the refrigerant level is too low, the AC system will not work properly.

To check the refrigerant level, you’ll need to use a refrigerant manifold gauge set. This tool will allow you to measure the pressure of the refrigerant in the system.

The normal refrigerant pressure for a 2012 Volkswagen Jetta is between 25 and 35 psi. If the pressure is too low, you’ll need to add more refrigerant to the system.

Step 4: Check the evaporator core

The evaporator core is a small radiator that is located in the dashboard. The evaporator core is responsible for cooling the air that is blown into the cabin.

If the evaporator core is dirty or clogged, it can restrict the flow of air and cause the AC system to not work properly.

To check the evaporator core, you’ll need to remove the glove box. Once the glove box is removed, you’ll be able to see the evaporator core.

Use a flashlight to inspect the evaporator core for any signs of damage or blockage. If the evaporator core is dirty, you can clean it with a mild detergent and water.

Step 5: Check the condenser

The condenser is a large radiator that is located in front of the radiator. The condenser is responsible for removing heat from the refrigerant gas.

If the condenser is dirty or clogged, it can restrict the flow of air and cause the AC system to not work properly.

To check the condenser, you’ll need to remove the front bumper. Once the front bumper is removed, you’ll be able to see the condenser.

Use a flashlight to inspect the condenser for any signs of damage or blockage. If the condenser is dirty, you can clean it with a mild detergent and water.

Step 6: Check the A/C control module

The A/C control module is a computer that controls the operation of the AC system. If the A/C control module is malfunctioning, it can cause the AC system to not work properly.

To check the A/C control module, you’ll need to use a diagnostic tool to scan the system for codes. If there are any codes, they will help you to identify the problem.

Step 7: Replace the faulty parts

Once you have identified the problem, you can replace the faulty parts and get your AC system up and running again.
