How to Fix B1244 Wiper Rear Motor Run Relay Circuit Failure

Introduction

If you’re experiencing the B1244 error code on your car, it means that there’s a problem with the wiper rear motor run relay circuit. This can be a frustrating issue to deal with, especially if you rely on your wipers to keep your windshield clear during inclement weather. Fortunately, fixing this problem is relatively straightforward, and you can do it yourself with a few basic tools and some know-how.

Step-by-Step Guide

Step 1: Check the Fuse

The first thing you should do when you encounter the B1244 error code is to check the fuse. The fuse is responsible for protecting the circuit from electrical surges and can sometimes blow out, causing the wiper rear motor run relay circuit to fail. To check the fuse, locate the fuse box in your car and find the wiper fuse. If the fuse is blown, replace it with a new one of the same amperage.

Step 2: Inspect the Wiring

If the fuse is not the problem, the next step is to inspect the wiring. Look for any signs of damage or wear, such as frayed wires or loose connections. If you find any issues, repair or replace the damaged wiring as necessary.

Step 3: Check the Relay

If the wiring is not the issue, the next step is to check the relay. The relay is responsible for controlling the flow of electricity to the wiper motor, and if it’s not functioning correctly, it can cause the wiper rear motor run relay circuit to fail. To check the relay, locate it in your car’s fuse box and remove it. Use a multimeter to test the relay’s continuity. If the relay is faulty, replace it with a new one.

Step 4: Test the Wiper Motor

If the relay is not the problem, the next step is to test the wiper motor. To do this, disconnect the motor from the wiring harness and use a multimeter to test its continuity. If the motor is faulty, replace it with a new one.

Useful Tips

– Always disconnect the battery before working on any electrical components in your car.
– Use a multimeter to test for continuity and voltage.
– Refer to your car’s owner’s manual for specific instructions and diagrams.

Conclusion

Fixing the B1244 error code on your car’s wiper rear motor run relay circuit is a relatively simple process that you can do yourself with a few basic tools and some know-how.
