How to Diagnose and Solve B2354 Driver Mirror Horizontal / Vertical Feedback Potentiometer Circuit Open Issues

Introduction

As a car owner, you may encounter various issues with your vehicle, including electrical problems. One of the most common issues is the B2354 driver mirror horizontal/vertical feedback potentiometer circuit open problem. This issue can cause your mirror to malfunction, making it difficult to adjust your view while driving. In this article, we will guide you on how to diagnose and solve this issue.

What is the B2354 Driver Mirror Horizontal / Vertical Feedback Potentiometer Circuit Open Issue?

The B2354 driver mirror horizontal/vertical feedback potentiometer circuit open issue is a problem that occurs when the feedback potentiometer circuit in the driver’s side mirror fails to function correctly. This circuit is responsible for adjusting the mirror’s position horizontally and vertically. When the circuit fails, the mirror will not adjust correctly, making it difficult to see while driving.

Diagnosing the B2354 Driver Mirror Horizontal / Vertical Feedback Potentiometer Circuit Open Issue

To diagnose the B2354 driver mirror horizontal/vertical feedback potentiometer circuit open issue, you will need a multimeter. Follow these steps:

Step 1: Locate the Mirror Feedback Potentiometer

The mirror feedback potentiometer is located inside the driver’s side mirror. You will need to remove the mirror cover to access it.

Step 2: Test the Potentiometer

Using a multimeter, test the potentiometer’s resistance by connecting the multimeter’s probes to the potentiometer’s terminals. The resistance should be between 0 and 5 ohms. If the resistance is outside this range, the potentiometer is faulty.

Step 3: Check the Wiring

If the potentiometer’s resistance is within the correct range, check the wiring for any damage or breaks. Use the multimeter to test the wiring’s continuity by connecting the probes to each end of the wire. If there is no continuity, the wire is broken and needs to be replaced.

Solving the B2354 Driver Mirror Horizontal / Vertical Feedback Potentiometer Circuit Open Issue

Once you have diagnosed the issue, you can proceed to solve it. Follow these steps:

Step 1: Replace the Potentiometer

If the potentiometer is faulty, you will need to replace it. You can purchase a replacement potentiometer from your local auto parts store or online. Follow the manufacturer’s instructions to install the new potentiometer.

Step 2: Repair the Wiring

If the wiring is broken, you will need to repair it. Cut the damaged section of the wire and strip the ends. Connect the two ends using a wire connector or soldering iron. Make sure the connection is secure and insulated.

Conclusion

The B2354 driver mirror horizontal/vertical feedback potentiometer circuit open issue can be frustrating, but it is a common problem that can be easily diagnosed and solved. By following the steps outlined in this article, you can diagnose the issue and fix it yourself, saving you time and money.
