What is the B1829 Wiper Rear High Limit Input Circuit Short To Ground Error Code?

The B1829 error code is related to the wiper system in your car. Specifically, it indicates that there is a short circuit in the wiper rear high limit input circuit, which is causing the wiper system to malfunction. This can result in the wipers not working at all, or working intermittently.

Diagnosing the Issue

Before you can fix the issue, you need to diagnose it. Here are the steps you should take:

Step 1: Check the Wiper Fuse

The first thing you should do is check the wiper fuse. If the fuse is blown, it can cause the wiper system to malfunction. To check the fuse, consult your car’s owner’s manual to locate the fuse box. Once you’ve found it, look for the wiper fuse and check if it’s blown. If it is, replace it with a new one and see if that solves the issue.

Step 2: Check the Wiper Motor

If the fuse is not the issue, the next thing you should check is the wiper motor. To do this, you’ll need a multimeter. First, disconnect the wiper motor from the car’s electrical system. Then, use the multimeter to check the resistance of the motor. If the resistance is not within the manufacturer’s specifications, the motor may be faulty and need to be replaced.

Step 3: Check the Wiring

If the wiper motor is not the issue, the next thing you should check is the wiring. Look for any signs of damage or wear and tear in the wiring. If you find any, repair or replace the wiring as necessary.

Step 4: Check the Wiper Switch

If the wiring is not the issue, the next thing you should check is the wiper switch. To do this, you’ll need to remove the switch from the car and test it with a multimeter. If the switch is faulty, it will need to be replaced.

Solving the Issue

Once you’ve diagnosed the issue, it’s time to solve it. Here are the steps you should take:

Step 1: Replace the Faulty Component

If you’ve determined that the wiper motor, wiring, or switch is faulty, you’ll need to replace the component. Consult your car’s owner’s manual or a repair manual to determine the exact steps you need to take to replace the component.

Step 2: Test the Wiper System

After you’ve replaced the faulty component, test the wiper system to ensure that it’s working properly. Turn on the wipers and observe their movement. If they’re working correctly, you’ve solved the issue.
