Introduction

If you own a 1999 Audi A6 and your AC blower motor is not working properly, then you might have a problem with your blower motor resistor. The blower motor resistor controls the speed of the blower motor, and if it malfunctions, it can cause a range of issues. In this article, we will discuss common problems associated with the 1999 Audi A6 AC blower motor resistor and how to fix them.

What is a blower motor resistor?

A blower motor resistor is a small electrical component that regulates the speed of the AC blower motor. It is located near the blower motor and is connected to it through a wiring harness. The resistor is made up of several resistors that are connected in series. The amount of current that flows through the resistors determines the speed of the blower motor.

Common Problems

There are several common problems associated with the 1999 Audi A6 AC blower motor resistor. Some of these include:

1. Blower motor only works on high speed

If your blower motor only works on high speed, then it is likely that the blower motor resistor has failed. This is a common problem and can be fixed by replacing the resistor.

2. Blower motor does not work at all

If your blower motor does not work at all, then it is likely that the blower motor resistor has failed completely. This can be fixed by replacing the resistor.

3. Blower motor works intermittently

If your blower motor works intermittently, then it is likely that the blower motor resistor is failing. This can be fixed by replacing the resistor.

How to Fix the Problem

If you are experiencing any of the above problems, then you will need to replace the blower motor resistor. Here is how to do it:

Step 1: Locate the resistor

The blower motor resistor is located near the blower motor, usually behind the glove box. It is connected to the blower motor through a wiring harness.

Step 2: Remove the old resistor

Disconnect the wiring harness from the old resistor and remove it from the vehicle. You may need to remove other components to gain access to the resistor.

Step 3: Install the new resistor

Install the new resistor in the same location as the old one. Connect the wiring harness to the new resistor.

Step 4: Test the blower motor

Turn on the AC and test the blower motor to ensure that it is working properly.

Conclusion

The 1999 Audi A6 AC blower motor resistor is an essential component of the AC system. If it fails, it can cause a range of problems with the blower motor. However, replacing the resistor is a relatively simple task that can be completed by most DIY mechanics. If you are experiencing any problems with your blower motor, then replacing the resistor may be the solution.
