How to Diagnose and Solve B1466 Wiper Hi/Low Speed Not Switching Issues

Introduction

If you’re experiencing issues with your wiper not switching between high and low speeds, you may have a B1466 error code. This can be frustrating, especially during inclement weather. However, diagnosing and solving this issue is relatively simple and can be done with a few basic tools. In this article, we’ll walk you through the steps to diagnose and solve B1466 wiper hi/low speed not switching issues.

Step 1: Check the Wiper Motor

The first step in diagnosing this issue is to check the wiper motor. Start by locating the wiper motor, which is typically located under the hood near the windshield. Check the wiring and connections to ensure they are secure and not damaged. If the wiring and connections are in good condition, use a multimeter to test the voltage at the motor. If the voltage is within the manufacturer’s specifications, the motor is likely functioning correctly.

Step 2: Check the Wiper Switch

If the wiper motor is functioning correctly, the next step is to check the wiper switch. The wiper switch is typically located on the steering column or dashboard. Check the wiring and connections to ensure they are secure and not damaged. If the wiring and connections are in good condition, use a multimeter to test the voltage at the switch. If the voltage is within the manufacturer’s specifications, the switch is likely functioning correctly.

Step 3: Check the Wiper Relay

If both the wiper motor and switch are functioning correctly, the next step is to check the wiper relay. The wiper relay is typically located in the fuse box under the hood. Check the wiring and connections to ensure they are secure and not damaged. If the wiring and connections are in good condition, use a multimeter to test the voltage at the relay. If the voltage is within the manufacturer’s specifications, the relay is likely functioning correctly.

Step 4: Check the Wiper Control Module

If all of the above components are functioning correctly, the issue may be with the wiper control module. The wiper control module is typically located under the dashboard. Check the wiring and connections to ensure they are secure and not damaged. If the wiring and connections are in good condition, use a multimeter to test the voltage at the module. If the voltage is within the manufacturer’s specifications, the module is likely functioning correctly.

Step 5: Replace the Faulty Component

Once you have identified the faulty component, it’s time to replace it. You can purchase replacement parts from your local auto parts store or online. Follow the manufacturer’s instructions to install the new component. Once the new component is installed, test the wipers to ensure they are functioning correctly.

Conclusion

Diagnosing and solving B1466 wiper hi/low speed not switching issues is relatively simple and can be done with a few basic tools. By following the steps outlined in this article, you can identify the faulty component and replace it, restoring your wipers to full functionality.
