Frequently Asked Questions
What is a Rear Windshield Wiper?
A rear windshield wiper is a crucial component of a vehicle’s rear window system, responsible for clearing water, snow, and debris from the rear glass. It typically consists of a wiper arm, a wiper blade, and a motor or other actuation mechanism. Rear windshield wipers are essential for maintaining visibility and ensuring safe driving conditions, particularly in rainy, snowy, or dusty weather.
How Does a Rear Windshield Wiper Work?
A rear windshield wiper works by using a motor or other actuation mechanism to move the wiper arm back and forth across the rear glass. The wiper blade, attached to the wiper arm, makes contact with the glass and wipes away water, snow, or debris. The speed and direction of the wiper can usually be adjusted using a control switch or lever, allowing drivers to customize the wiper’s performance to suit different weather conditions.
Why Should I Replace My Rear Windshield Wiper?
You should replace your rear windshield wiper if it is no longer functioning properly or has become worn out. A malfunctioning rear windshield wiper can reduce visibility and increase the risk of accidents, particularly in poor weather conditions. Additionally, a worn-out rear windshield wiper may not be effective at clearing water or debris, which can lead to water spots or scratches on the rear glass. Replacing a rear windshield wiper is a relatively simple and cost-effective way to maintain your vehicle’s safety and appearance.
How Do I Start Replacing My Rear Windshield Wiper?
To replace your rear windshield wiper, start by purchasing a new wiper assembly or wiper blade, depending on your vehicle’s specific requirements.

Next, locate the wiper motor or actuation mechanism and disconnect any electrical connections or bolts holding the wiper arm in place. Gently pull the wiper arm away from the rear glass and remove the old wiper blade or assembly. Install the new wiper blade or assembly, reconnect any electrical connections or bolts, and test the wiper to ensure it is working properly.
What If My Rear Windshield Wiper Is Not Working?
If your rear windshield wiper is not working, first check the electrical connections and ensure they are secure and not damaged. Next, inspect the wiper motor or actuation mechanism for any blockages or worn-out parts. If the issue persists, consult your owner’s manual or manufacturer’s instructions for troubleshooting guidance. In some cases, it may be necessary to replace the wiper motor or other components. If you are unsure or uncomfortable with DIY repairs, consider consulting a professional mechanic or auto electrician for assistance.
Which Rear Windshield Wiper Is Better: Mechanical or Electric?
The choice between a mechanical and electric rear windshield wiper depends on your vehicle’s specific requirements and your personal preferences. Mechanical wipers are generally more affordable and easy to replace, but may require more maintenance and may not provide the same level of performance as electric wipers. Electric wipers, on the other hand, are typically more convenient and provide faster, more efficient operation, but may be more expensive to replace and require more complex installation.
How Much Does It Cost to Replace a Rear Windshield Wiper?
The cost to replace a rear windshield wiper can vary depending on the type of wiper, vehicle make and model, and location. On average, a new rear windshield wiper assembly or wiper blade can cost between $20 and $100. However, if you need to replace the wiper motor or other components, the cost can range from $50 to $200 or more, depending on the complexity of the repair. It’s essential to consult your owner’s manual or manufacturer’s instructions for guidance on selecting the correct replacement part and estimating the cost of the repair.

Can I Use a Front Windshield Wiper on My Rear Window?
No, you should not use a front windshield wiper on your rear window. Front and rear windshield wipers are designed to work with different types of glass and are typically tailored to the specific needs of each window. Using a front windshield wiper on your rear window may not provide the same level of performance or may even damage the wiper or the rear glass.
