Volkswagen Vento Ac Not Working

As a certified Volkswagen service technician, I have seen many cases of Volkswagen Vento AC not working. This is a common problem that can be frustrating and inconvenient for drivers. The good news is that it is usually an easy fix. This guide will walk you through the steps to troubleshoot and potentially resolve the issue. By the end of this guide, you will be able to get your Vento’s AC back up and running in no time.

Why Volkswagen Vento Ac Not Working

Low Refrigerant Level

The most common reason for a Volkswagen Vento AC not working is a low refrigerant level. The refrigerant is a gas that flows through the AC system and absorbs heat from the air inside the car. When the refrigerant level is low, the AC system cannot work properly and the air inside the car will not be cooled.

Faulty Compressor

The compressor is the heart of the AC system. It is responsible for compressing the refrigerant gas and sending it through the AC system. If the compressor is faulty, the AC system will not be able to work properly.

Faulty Expansion Valve

The expansion valve is a small valve that controls the flow of refrigerant gas through the AC system. If the expansion valve is faulty, the AC system will not be able to work properly.

Faulty Condenser

The condenser is a radiator-like device that cools the refrigerant gas and condenses it back into a liquid. If the condenser is faulty, the AC system will not be able to work properly.

Faulty Evaporator

The evaporator is a small radiator-like device that cools the air inside the car. If the evaporator is faulty, the AC system will not be able to work properly.

Faulty Control Unit

The control unit is a computer that controls the operation of the AC system. If the control unit is faulty, the AC system will not be able to work properly.

How to Troubleshoot: Volkswagen Vento AC Not Working

Your Volkswagen Vento’s air conditioner is a vital part of keeping you cool and comfortable on hot days. But what happens when your AC stops working? Don’t panic! There are a few things you can check to troubleshoot the problem and get your AC back up and running in no time.

Step 1: Check the fuses

The first thing you should do is check the fuses for your AC. Fuses are small, cylindrical pieces of metal that protect your car’s electrical system from damage. If a fuse blows, it will prevent power from flowing to your AC compressor, which will cause your AC to stop working.

To check the fuses, locate the fuse box in your Volkswagen Vento. The fuse box is usually located under the hood or in the passenger compartment. Once you’ve found the fuse box, look for a fuse that’s labeled AC or A/C. Remove the fuse and inspect it for damage. If the fuse is blown, replace it with a new fuse that has the same amperage rating.

Step 2: Check the compressor clutch

The compressor clutch is a small, electric motor that engages and disengages the AC compressor. When the compressor clutch is engaged, it turns the compressor, which pumps refrigerant through the AC system. If the compressor clutch is not engaging, your AC will not work.

To check the compressor clutch, start your Volkswagen Vento and turn on the AC. Listen for the compressor to engage. You should hear a whining noise coming from the engine bay. If you don’t hear the compressor engage, the compressor clutch may be faulty.

You can also check the compressor clutch by using a voltmeter. Disconnect the electrical connector from the compressor clutch. With the AC turned on, the voltmeter should read 12 volts. If the voltmeter does not read 12 volts, the compressor clutch may be faulty.

Step 3: Check the refrigerant level

Refrigerant is a vital part of your AC system. It helps to cool the air that’s blown through your vents. If your refrigerant level is low, your AC will not work properly.

To check the refrigerant level, you’ll need a refrigerant manifold gauge. A refrigerant manifold gauge is a tool that measures the pressure of the refrigerant in your AC system.

To use a refrigerant manifold gauge, connect the gauge to the high and low side of your AC system. Then, start your Volkswagen Vento and turn on the AC. The gauge should read between 25 and 35 psi on the high side and between 10 and 20 psi on the low side. If the pressures are too low, you’ll need to add refrigerant to your AC system.

Step 4: Check the AC condenser

The AC condenser is a radiator-like device that’s located in front of your Volkswagen Vento’s radiator. The condenser’s job is to cool the refrigerant that’s been compressed by the compressor. If the condenser is dirty or clogged, it can restrict airflow and cause your AC to not work properly.

To check the condenser, look for any signs of dirt or debris. If you see any dirt or debris, clean the condenser with a hose. You can also use a leaf blower to blow the dirt and debris away.

Step 5: Check the AC evaporator

The AC evaporator is a small, metal device that’s located inside your Volkswagen Vento’s dashboard. The evaporator’s job is to turn the refrigerant back into a gas. If the evaporator is dirty or clogged, it can restrict airflow and cause your AC to not work properly.

To check the evaporator, look for any signs of dirt or debris. If you see any dirt or debris, clean the evaporator with a hose. You can also use a leaf blower to blow the dirt and debris away.

Step 6: Check the AC blower motor

The AC blower motor is a small, electric motor that blows air through the vents. If the blower motor is not working properly, your AC will not blow cold air.

To check the blower motor, start your Volkswagen Vento and turn on the AC. Listen for the blower motor to turn on. You should hear a whirring noise coming from the passenger compartment. If you don’t hear the blower motor turn on, the blower motor may be faulty.

You can also check the blower motor by using a multimeter. Disconnect the electrical connector from the blower motor. With the AC turned on,
