Windshield Wipers For 2018 Nissan Altima

Hey there, Nissan Altima owners! Having trouble seeing clearly through your windshield? Chances are, your wipers are to blame. Let's talk about common windshield wiper problems on the 2018 Nissan Altima and, more importantly, how to fix them.

Common 2018 Nissan Altima Wiper Issues

The 2018 Altima, like any car, can experience a few common wiper-related problems. Here’s a breakdown of what you might be dealing with:

Streaking or Smearing

This is probably the most frequent complaint. Streaking happens when the rubber blade isn't making full, clean contact with the windshield. Instead of wiping away water, it leaves behind annoying lines. Smearing is similar, but instead of distinct lines, you get a hazy film of water and debris.

Causes:

  • Worn Wiper Blades: This is the most likely culprit. Wiper blades are made of rubber, which deteriorates over time due to sunlight, heat, and abrasion. Expect to replace them every 6-12 months, depending on your local weather conditions and how often you use them.
  • Dirty Windshield: Believe it or not, a dirty windshield can cause streaking. Road grime, bug splatters, and tree sap can all interfere with the blade's ability to make clean contact.
  • Damaged Wiper Blades: Sometimes, the blade itself is torn, cracked, or chipped. This can happen if something impacts the blade, like ice or a stray rock.
  • Contaminated Wiper Blades: Wax, silicone, or even certain car washes can leave a residue on the blade, preventing it from working properly.

Skipping or Chattering

Skipping refers to the wipers jumping or shuddering across the windshield instead of moving smoothly. Chattering is a similar issue, producing a noticeable vibrating sound as the wipers operate.

Causes:

  • Dry Windshield: Running your wipers on a dry windshield can cause friction and lead to skipping. Always use the windshield washer fluid.
  • Wiper Arm Angle: The angle of the wiper arm to the windshield may be incorrect. If the arm is bent or misaligned, it won't apply even pressure across the blade.
  • Worn Wiper Blades: As with streaking, worn blades are a common cause of skipping. The rubber loses its flexibility and can't conform to the windshield's curve.
  • Wiper Linkage Issues: While less common, problems with the wiper linkage (the mechanical system that moves the wipers) can cause erratic movement.

Wipers Not Working At All

A complete failure of the wipers can be a serious safety hazard, especially in heavy rain or snow.

Causes:

  • Blown Fuse: This is usually the first thing to check. A blown fuse will cut power to the wiper motor.
  • Faulty Wiper Motor: The wiper motor is responsible for powering the wipers. If it fails, the wipers won't move.
  • Wiper Switch Problems: A malfunctioning wiper switch can prevent the wipers from receiving power.
  • Wiring Issues: Damaged or corroded wiring can interrupt the electrical signal to the wiper motor.
  • Wiper Linkage Issues: As mentioned before, a broken or disconnected linkage can prevent the motor's power from reaching the wipers.

Slow Wiper Speed

If your wipers are moving noticeably slower than usual, even on the highest setting, there's likely an underlying problem.

Causes:

  • Low Voltage: A weak battery or charging system can reduce the voltage available to the wiper motor, causing it to run slowly.
  • Wiper Motor Problems: The wiper motor might be wearing out or experiencing internal resistance, slowing down its operation.
  • Wiper Linkage Issues: Stiff or binding linkage can put extra strain on the motor, making it run slower.

Troubleshooting and Solutions

Now that we've identified the common issues, let's get to the solutions! Here’s a step-by-step guide to troubleshooting and fixing your 2018 Altima's windshield wipers.

1. Inspect the Wiper Blades

This is the easiest and most frequent fix. Examine the blades closely for:

  • Cracks or Tears: Any visible damage indicates the blade needs replacement.
  • Rounded Edges: The wiping edge should be sharp and clean. Rounded edges mean the rubber is worn.
  • Hardening or Stiffness: The blade should be flexible. If it feels hard or brittle, it's time to replace it.

Solution: Replace the wiper blades. You can find replacement blades at most auto parts stores. Make sure you get the correct size for your 2018 Altima. The owner's manual will specify the correct length. Installation is usually straightforward; most blades simply clip onto the wiper arm. Follow the instructions on the new blade's packaging.

Tools Needed: None usually required, but a small flathead screwdriver *might* be helpful depending on the blade attachment style.

Approximate Cost: $20 - $50 for a pair of blades.

2. Clean the Windshield and Wiper Blades

A clean windshield and blades can make a surprisingly big difference.

Solution:

  • Wash the Windshield: Use a good quality glass cleaner and a clean microfiber cloth. Pay attention to removing any stubborn grime, bug splatters, or tree sap.
  • Clean the Wiper Blades: Wipe the rubber blades with a damp cloth or paper towel to remove any dirt or debris. You can also use a small amount of glass cleaner on the cloth, but be sure to wipe the blades dry afterwards.

Tools Needed: Glass cleaner, microfiber cloth, water.

Approximate Cost: Minimal - just the cost of cleaning supplies.

3. Check the Windshield Washer Fluid

Ensure your washer fluid reservoir is full and that the fluid is spraying correctly.

Solution:

  • Refill the Reservoir: Use a quality windshield washer fluid that's designed for your climate.
  • Check the Nozzles: Make sure the spray nozzles are aimed correctly. You can use a small pin or needle to adjust the direction of the spray.

Tools Needed: None.

Approximate Cost: $5 - $10 for windshield washer fluid.

4. Inspect the Wiper Arms

Check that the wiper arms are securely attached to the wiper motor linkage and that they aren't bent or damaged.

Solution:

  • Tighten Loose Arms: If the wiper arm is loose, tighten the nut or screw that holds it in place.
  • Straighten Bent Arms: If the arm is bent, you *might* be able to carefully bend it back into shape. However, it’s often better to replace the arm if it's significantly damaged.

Tools Needed: Wrench or socket set, pliers (if bending the arm).

Approximate Cost: $20 - $50 per wiper arm (if replacement is needed).

5. Check the Fuse

If the wipers aren't working at all, a blown fuse is a likely cause. Locate the fuse box (usually under the dashboard or in the engine compartment – consult your owner's manual) and check the fuse for the windshield wipers. The fuse diagram in your owner's manual will identify the correct fuse.

Solution:

  • Replace the Blown Fuse: If the fuse is blown (the wire inside is broken), replace it with a new fuse of the same amperage.

Tools Needed: Fuse puller (usually located in the fuse box), replacement fuse.

Approximate Cost: $2 - $5 for a replacement fuse.

Important: If the fuse blows repeatedly, there's likely a short circuit in the wiper system. This requires further diagnosis by a qualified mechanic.

6. Test the Wiper Motor and Switch

If the fuse is good, the problem might be with the wiper motor or the wiper switch.

Solution:

  • Wiper Motor: Testing the wiper motor usually requires a multimeter and some electrical knowledge. You can check for voltage at the motor connector. If there's voltage but the motor isn't running, the motor is likely faulty.
  • Wiper Switch: Testing the switch also requires a multimeter. You can check for continuity in different switch positions.

Tools Needed: Multimeter, wiring diagram (available in a repair manual or online).

Approximate Cost: Wiper motor replacement can range from $100 - $300, including labor. Wiper switch replacement can be similar in cost, but may be less depending on the complexity of the switch.

Important Note: Testing and replacing the wiper motor or switch can be complex and may require specialized tools. If you're not comfortable working with electrical systems, it's best to take your Altima to a qualified mechanic.

7. Check the Wiper Linkage

Inspect the wiper linkage for any signs of damage, wear, or disconnection. The linkage connects the wiper motor to the wiper arms and transmits the motor's movement to the blades.

Solution:

  • Reconnect Disconnected Linkage: If the linkage is disconnected, try to reconnect it. You may need to remove the wiper arms to access the linkage.
  • Replace Damaged Linkage: If the linkage is bent, broken, or excessively worn, it needs to be replaced.

Tools Needed: Wrench or socket set, pliers.

Approximate Cost: Wiper linkage replacement can range from $80-$250, depending on the specific part and labor costs.
