We’ll guide you through a comprehensive step-by-step process to identify and address the issue effectively. Whether you’re a seasoned DIY enthusiast or a novice looking to learn, this guide will provide you with the knowledge and confidence to fix your windshield wiper and restore clear visibility during inclement weather.
Understanding Wiper Motors
Windshield wipers are powered by a motor that converts electrical energy into mechanical motion. The motor is connected to the wiper linkage, which transfers the motion to the wiper blades, causing them to sweep across the windshield. If the wiper motor fails, the wipers will not move, regardless of the wiper switch position.
There are two main types of wiper motors: electric motors and vacuum motors. Electric motors are typically used in newer vehicles, while vacuum motors are more common in older cars. Both types can fail, but electric motors are generally more reliable.
Troubleshooting a Non-Moving Wiper
Before you start replacing parts, it’s essential to troubleshoot the problem to identify the root cause. Here are a few steps you can take:
- Check the fuse: The wiper motor is connected to a fuse that protects it from electrical overloads. If the fuse is blown, the motor will not receive power, and the wipers will not move. Check the fuse box and replace the blown fuse if necessary.
- Inspect the wiper switch: The wiper switch is responsible for sending power to the wiper motor. If the switch is damaged or faulty, it may not send the necessary signal to the motor. Try operating the switch several times and listen for a clicking sound. If you don’t hear a click, the switch may be faulty.
- Check the wiring: The wiper motor is connected to the electrical system by a bundle of wires. These wires can become damaged or disconnected over time, leading to a loss of power to the motor. Inspect the wires for any visible damage or loose connections.
Replacing the Wiper Motor
If you’ve checked the fuse, wiper switch, and wiring, and the wiper motor is still not working, it may need to be replaced. Replacing a wiper motor requires some mechanical knowledge and tools, but it’s a relatively straightforward process.
Here’s a step-by-step guide to replacing the wiper motor:
- Disconnect the negative battery terminal.
- Locate the wiper motor, which is usually mounted on the firewall or under the windshield cowl.
- Disconnect the electrical connector from the wiper motor.
- Unbolt the wiper motor from the firewall or cowl.
- Remove the wiper motor and linkage from the vehicle.
- Install the new wiper motor and linkage, following the reverse steps of removal.
- Reconnect the electrical connector to the wiper motor.
- Reconnect the negative battery terminal.
- Test the wipers to make sure they are working properly.

Tips and Expert Advice
Here are some tips and advice from expert mechanics:
- Use the correct tools for the job. A pair of pliers, a wrench, and a screwdriver are usually sufficient.
- Be careful not to overtighten the bolts when installing the new wiper motor. Overtightening can damage the motor.
- If you are not comfortable replacing the wiper motor yourself, take your vehicle to a qualified mechanic.
