1999 Volkswagen Jetta Ac Fans Not Working [Solved]

Do you own a 1999 Volkswagen Jetta and your AC fans are not working You’re not alone. This is a common problem that can be frustrating and inconvenient. But don’t worry, I’m here to help. In this troubleshooting guide, I’ll walk you through the steps to diagnose and fix the problem. So you can get your AC back up and running in no time.

Reasons Why 1999 Volkswagen Jetta Ac Fans Not Working

Bad blower motor resistor

The blower motor resistor is a small electronic component that controls the speed of the blower motor. If the resistor is bad, the blower motor may not work at all, or it may only work on high speed.

Bad blower motor

The blower motor is the motor that actually moves the air through the vents. If the blower motor is bad, it will not be able to move any air, and the AC will not work.

Bad wiring

The wiring to the blower motor can become damaged, which can prevent the blower motor from working.

Faulty climate control module

The climate control module is the computer that controls the AC system. If the climate control module is faulty, it may not be able to send the correct signals to the blower motor, and the AC will not work.

Low freon

The AC system uses freon to cool the air. If the freon level is low, the AC will not be able to cool the air effectively, and the blower motor may work harder than necessary, which can damage it.

How to Troubleshoot: 1999 Volkswagen Jetta AC Fans Not Working

The air conditioner (AC) in your 1999 Volkswagen Jetta is an important part of keeping you cool and comfortable during hot weather. If the AC fans are not working, the air conditioner will not be able to cool the air in the cabin. This can be a very uncomfortable problem, especially in hot weather.

There are a few things that could be causing the AC fans not to work. In this article, we will discuss the most common causes and how to troubleshoot them.

Causes of AC Fans Not Working

There are a few different things that could cause the AC fans not to work. Some of the most common causes include:

A blown fuse:

The AC fans are powered by a fuse. If the fuse is blown, the fans will not be able to get power and will not work.

A faulty relay:

The AC fans are controlled by a relay. If the relay is faulty, it can prevent the fans from getting power and will not work.

A bad blower motor:

The blower motor is the part of the AC system that actually moves the air. If the blower motor is bad, it will not be able to move the air and the AC will not work.

A clogged air filter:

The air filter helps to keep dirt and debris out of the AC system. If the air filter is clogged, it can restrict airflow and prevent the AC from working properly.

A low refrigerant level:

The refrigerant is a gas that is used to cool the air in the AC system. If the refrigerant level is low, the AC will not be able to cool the air properly.

Troubleshooting AC Fans Not Working

If the AC fans are not working, you can troubleshoot the problem by following these steps:

1. Check the fuses:
First, check the fuses in the fuse box to see if any of them are blown. If a fuse is blown, replace it with a new fuse of the same amperage.

2. Check the relays:
Next, check the relays in the fuse box to see if any of them are faulty. If a relay is faulty, replace it with a new relay of the same type.3. Check the blower motor:
If the fuses and relays are good, the next step is to check the blower motor. To do this, you will need to remove the blower motor from the car. Once the blower motor is removed, you can check it for damage. If the blower motor is bad, you will need to replace it.

4. Check the air filter:
The next step is to check the air filter. To do this, you will need to remove the air filter from the car. Once the air filter is removed, you can check it for dirt and debris. If the air filter is clogged, you will need to clean it or replace it.

5. Check the refrigerant level:
The last step is to check the refrigerant level. To do this, you will need to use a refrigerant manifold gauge. Once the refrigerant manifold gauge is connected to the AC system, you can check the refrigerant level. If the refrigerant level is low, you will need to add refrigerant to the system.

Conclusion

The AC fans in your 1999 Volkswagen Jetta are an important part of keeping you cool and comfortable during hot weather. If the AC fans are not working, you can troubleshoot the problem by following the steps in this article. By following these steps, you can hopefully get your AC fans working again and enjoy cool, comfortable air in your car.

FAQs: 1999 Volkswagen Jetta AC Fans Not Working

Why are my 1999 Volkswagen Jetta AC fans not working?

There are a few possible reasons why your 1999 Volkswagen Jetta AC fans may not be working.

The blower motor is not working: This is the most common cause of AC fan problems. The blower motor is responsible for blowing air through the evaporator core, which cools the air before it is blown into the cabin. If the blower motor is not working, the air will not be cooled and the AC will not work.

The AC compressor is not working: The AC compressor is responsible for compressing the refrigerant gas, which creates the cold air. If the AC compressor is not working, the refrigerant gas will not be compressed and the air will not be cooled.

The condenser fan is not working: The condenser fan is responsible for cooling the refrigerant gas after it has been compressed by the AC compressor. If the condenser fan is not working, the refrigerant gas will not be cooled and the AC will not work.

The evaporator fan is not working: The evaporator fan is responsible for blowing air across the evaporator core, which cools the air before it is blown into the cabin. If the evaporator fan is not working, the air will not be cooled and the AC will not work.

The AC control head is not working properly: The AC control head is responsible for sending signals to the various AC components, telling them when to turn on and off. If the AC control head is not working properly, the AC may not work correctly.
