How to Fix B1269 Servo Motor Potentiometer Defrost Circuit Open

Introduction

If you’re experiencing the B1269 error code on your car, it means that there’s an issue with the servo motor potentiometer defrost circuit. This can be a frustrating problem to deal with, but fortunately, it’s something that you can fix on your own with a little bit of know-how. In this article, we’ll walk you through the steps you need to take to fix the B1269 error code and get your car back up and running smoothly.

Step 1: Diagnose the Problem

Before you can fix the B1269 error code, you need to diagnose the problem. This error code is typically caused by a faulty servo motor potentiometer defrost circuit, which can be caused by a number of different issues. Some common causes of this problem include a damaged wiring harness, a faulty servo motor, or a malfunctioning control module.

To diagnose the problem, you’ll need to use a diagnostic scanner to read the error codes stored in your car’s computer. Once you’ve identified the B1269 error code, you can use the scanner to read the freeze frame data, which will give you more information about the conditions that caused the error code to be triggered.

Step 2: Replace the Servo Motor Potentiometer

Once you’ve diagnosed the problem, the next step is to replace the faulty servo motor potentiometer. This is a relatively simple process that can be done with a few basic tools.

To replace the servo motor potentiometer, you’ll need to locate it in your car’s HVAC system. This component is typically located behind the dashboard, so you may need to remove some panels to access it. Once you’ve located the servo motor potentiometer, you can remove it by disconnecting the wiring harness and any mounting screws.

After you’ve removed the old servo motor potentiometer, you can install the new one by reversing the removal process. Make sure to connect the wiring harness and any mounting screws securely to ensure that the new component is properly installed.

Step 3: Test the System

After you’ve replaced the servo motor potentiometer, the next step is to test the system to make sure that the B1269 error code has been resolved. To do this, you’ll need to clear the error codes stored in your car’s computer using a diagnostic scanner.

Once you’ve cleared the error codes, you can test the system by turning on your car’s HVAC system and checking to see if the defrost circuit is working properly. If everything is working as it should, you should no longer see the B1269 error code.

Conclusion

Fixing the B1269 error code may seem like a daunting task, but with the right tools and a little bit of know-how, it’s something that you can do on your own. By following the steps outlined in this article, you can diagnose and fix the problem, and get your car back up and running smoothly.
