How to Fix B1344 Heated Backlite Input Circuit Open

Introduction

If you’re experiencing the B1344 error code on your car, it means that there’s an issue with the heated backlite input 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 B1344 error code and get your car back in working order.

Step 1: Check the Wiring

The first thing you should do when you encounter the B1344 error code is to check the wiring. This error code is often caused by a loose or damaged wire in the heated backlite input circuit. Start by inspecting the wiring for any visible signs of damage, such as frayed or broken wires. If you find any damaged wires, you’ll need to replace them.

Step 2: Check the Fuse

If the wiring looks okay, the next thing you should check is the fuse. The B1344 error code can also be caused by a blown fuse in the heated backlite input circuit. Locate the fuse box in your car and check the fuse for the heated backlite input circuit. If the fuse is blown, replace it with a new one.

Step 3: Check the Relay

If the wiring and fuse both look okay, the next thing you should check is the relay. The relay is responsible for sending power to the heated backlite input circuit, and if it’s not working properly, it can cause the B1344 error code. Locate the relay for the heated backlite input circuit and test it with a multimeter. If the relay is faulty, you’ll need to replace it.

Step 4: Check the Switch

If the wiring, fuse, and relay all look okay, the next thing you should check is the switch. The switch is what controls the heated backlite input circuit, and if it’s not working properly, it can cause the B1344 error code. Test the switch with a multimeter to see if it’s working properly. If the switch is faulty, you’ll need to replace it.

Step 5: Test the Heated Backlite

If all of the above steps have been completed and the B1344 error code is still present, the final step is to test the heated backlite itself. Use a multimeter to test the resistance of the heated backlite. If the resistance is outside of the manufacturer’s specifications, you’ll need to replace the heated backlite.

Conclusion

Fixing the B1344 error code may seem daunting at first, but with a little bit of know-how, it’s something that you can easily do on your own. By following the steps outlined in this article, you’ll be able to diagnose and fix the issue with your car’s heated backlite input circuit, and get your car back in working order.
