2015 Nissan Sentra Windshield Wiper Size

Okay, so you're having trouble finding the right windshield wipers for your 2015 Nissan Sentra? You're not alone! It can be a little confusing with all the different brands and sizes out there. Let's get you sorted out. This guide will cover the correct wiper sizes, potential problems you might encounter, and give you some practical tips to keep your visibility crystal clear.

Finding the Right Wiper Size

The correct windshield wiper blade sizes for a 2015 Nissan Sentra are 28 inches for the driver's side and 15 inches for the passenger side. Make sure you double-check this information against your specific vehicle's owner's manual, just to be absolutely certain. While it's rare, there can sometimes be slight variations depending on the specific trim level or any aftermarket modifications done to the car.

Why is the right size important? Using the wrong size wiper blade can lead to several problems:

• Ineffective Cleaning: Blades that are too short won't cover the entire windshield, leaving streaks and blind spots.
• Overlapping: If a blade is too long on the passenger side, it might overlap with the driver's side wiper, causing them to bind and potentially damage the wiper motor.
• Damage to Wiper Arms: Incorrectly sized wipers can put undue stress on the wiper arms, leading to premature wear and potential breakage.
• Poor Visibility: The ultimate goal is clear visibility, and that's compromised with incorrect wiper sizes. This is a safety issue!

Confirming the Size: A Few Methods

Here are a few ways to double-check that you have the right sizes:

• Consult Your Owner's Manual: As mentioned earlier, the owner's manual is the definitive source of information for your car. Look for the section on wiper blade replacement.
• Check Online Retailers: Most online auto parts retailers allow you to enter your vehicle's year, make, and model to find compatible parts, including wiper blades. Be sure to confirm the sizes they recommend.
• Use a Wiper Blade Size Guide: Many auto parts stores have physical or online wiper blade size guides that you can use to look up the correct sizes.
• Measure Your Existing Blades: If you still have the old wiper blades, you can simply measure them with a ruler or measuring tape.

Common Problems and Solutions

Beyond just getting the right size, you might encounter other issues when replacing your 2015 Sentra's wiper blades.

Problem 1: Wiper Blades Smearing or Streaking

Cause: This is usually due to worn or damaged wiper blades. Over time, the rubber edge of the blade deteriorates from exposure to sunlight, heat, and debris. It can also be caused by debris stuck on the wiper blade itself or on the windshield.

Solution:

1. Clean the Windshield: Thoroughly clean your windshield with glass cleaner to remove any dirt, grime, or residue that might be contributing to the smearing.
2. Clean the Wiper Blades: Use a clean cloth or paper towel dampened with windshield washer fluid to wipe down the rubber edge of the wiper blades. This can remove any embedded debris.
3. Replace the Wiper Blades: If cleaning doesn't solve the problem, it's time to replace the wiper blades. Wiper blades should typically be replaced every 6-12 months, depending on usage and environmental conditions.

Problem 2: Wiper Blades Skipping or Chattering

Cause: Skipping or chattering usually indicates that the wiper blades are not making proper contact with the windshield. This can be caused by:

• Worn Wiper Blades: Similar to smearing, worn blades lose their flexibility and can't conform to the shape of the windshield.
• Contaminated Windshield: Oil, wax, or other contaminants on the windshield can interfere with the wiper blades' ability to grip the glass.
• Wiper Arm Issues: A bent or weak wiper arm can prevent the blade from applying even pressure to the windshield.

Solution:

1. Clean and Treat the Windshield: Start by thoroughly cleaning the windshield with a degreasing glass cleaner. Consider using a clay bar to remove embedded contaminants. You could also try a water repellent windshield treatment like Rain-X.
2. Inspect the Wiper Arms: Carefully inspect the wiper arms for any signs of bending or damage. If an arm is bent, you may be able to carefully bend it back into shape. If it's severely damaged, it will need to be replaced.
3. Replace the Wiper Blades: Again, if the blades are old or worn, replacement is the best solution.

Problem 3: Wiper Blades Not Working at All

Cause: This could be due to a few things:

• Blown Fuse: The wiper motor is protected by a fuse. If the fuse blows, the wipers won't work.
• Faulty Wiper Motor: The wiper motor itself could be defective.
• Wiring Issues: A broken or damaged wire in the wiper circuit can prevent the motor from receiving power.
• Faulty Wiper Switch: The switch that controls the wipers could be malfunctioning.

Solution:

1. Check the Fuse: Consult your owner's manual to locate the fuse for the windshield wipers. Inspect the fuse to see if it's blown. If it is, replace it with a new fuse of the same amperage.
2. Check the Wiper Motor: This is a more complex repair that may require professional assistance. You can test the wiper motor with a multimeter to see if it's receiving power.
3. Inspect the Wiring: Look for any visible signs of damage to the wiring harness that connects to the wiper motor and switch.
4. Consult a Mechanic: If you're not comfortable troubleshooting electrical problems, it's best to take your car to a qualified mechanic for diagnosis and repair.

Replacing Your Wiper Blades: A Step-by-Step Guide

Replacing your wiper blades is a relatively easy task that most people can do themselves. Here's a general guide:

Tools Needed:

• New wiper blades (28" and 15" for a 2015 Nissan Sentra)
• Possibly a small screwdriver or pliers (depending on the wiper blade attachment type)
• Gloves (optional, to keep your hands clean)

Steps:

1. Lift the Wiper Arm: Carefully lift the wiper arm away from the windshield. Be gentle to avoid scratching the glass.
2. Locate the Wiper Blade Attachment: There are several different types of wiper blade attachments, including:
   • J-Hook: This is the most common type. The wiper blade has a hook that slides over a post on the wiper arm.
   • Pin Lock: The wiper blade is held in place by a pin that must be released.
   • Side Lock: The wiper blade has a clip that locks onto the wiper arm from the side.
3. Detach the Old Wiper Blade: Depending on the attachment type, you may need to squeeze tabs, push a button, or slide the blade off the arm. Refer to the instructions that came with your new wiper blades for specific guidance.
4. Attach the New Wiper Blade: Line up the new wiper blade with the wiper arm and attach it according to the manufacturer's instructions. Make sure it clicks or locks into place securely.
5. Lower the Wiper Arm: Carefully lower the wiper arm back onto the windshield.
6. Repeat for the Other Wiper Blade: Repeat the process for the other wiper blade.
7. Test the Wipers: Turn on your windshield wipers to make sure they are working properly.

Cost Considerations

Here's a rough estimate of the costs you might encounter:

• Wiper Blades: A decent set of standard wiper blades will typically cost between $15 and $30. Premium blades, such as those with silicone or beam designs, can cost more.
• Wiper Motor Replacement: If your wiper motor needs to be replaced, the cost can range from $150 to $400, including parts and labor.
• Wiper Arm Replacement: A new wiper arm typically costs between $20 and $50.
• Professional Diagnosis: If you take your car to a mechanic for diagnosis, you can expect to pay around $50 to $100 for a diagnostic fee.

Preventative Maintenance Tips

Here are some tips to help extend the life of your wiper blades and keep your windshield clean:

• Clean Your Windshield Regularly: Wash your windshield regularly with glass cleaner to remove dirt, grime, and debris.
• Clean Your Wiper Blades Regularly: Wipe down the rubber edge of your wiper blades with a damp cloth to remove any embedded debris.
• Use Windshield Washer Fluid: Always use windshield washer fluid in your washer reservoir. Water alone is not effective at removing dirt and grime. Also, never use your wipers on a dry windshield, as this will damage the blades.
• Park in the Shade: Parking your car in the shade can help protect your wiper blades from the damaging effects of sunlight and heat.
• Lift Your Wiper Blades in Winter: In cold climates, lift your wiper blades away from the windshield when parking to prevent them from freezing to the glass.

By following these tips and keeping your wiper blades in good condition, you can ensure clear visibility and safe driving in all weather conditions. Good luck!
