This blog post is here to assist you, addressing the causes of these malfunctions and offering practical tips for a solution. So, relax and let me guide you through straightforward do-it-yourself steps to get your windshield washer back in working order.

1. Fluid Reservoir Is Empty

The most straightforward yet crucial step to troubleshoot when your windshield washer fluid refuses to spray is checking the fluid level. Surprisingly, many people tend to overlook this simple fix.

Locate the transparent reservoir at the back of the engine bay, typically capped with a bright-colored plastic lid featuring a windshield symbol. If you’re not sure where to find it, consult your car’s manual. An empty reservoir could be due to human oversight or potential leaks in the washer hose or reservoir itself, so a thorough check is important.

Fix: Refill The Fluid Reservoir

Fill the reservoir with washer fluid. Don’t dare to use tap water as it’s like giving your car a drink full of impurities that can clog up the nozzles. Whether you’re in a cold or warm climate, tap water is a straight no.

Grab proper washer fluid, pour it into the reservoir, and give it about 10 seconds to work its magic.

2. Frozen Washer Fluid

Another possible explanation for your windshield wiper fluid playing hard to get is the cold weather—it might have turned into a solid. If your car has been sitting out in the cold, there’s a chance that the wiper fluid froze up, causing issues in the hose or nozzle.

How to Unfreeze Wiper Fluid:

Applying air pressure to the hose connected to the sprayer nozzle can help but If that doesn’t work, you can use a hairdryer or a heating element.

However, a word of caution: Don’t apply too much heat as it can harm the plastic parts of your car’s windshield washer system.

Preventive Measure:

To avoid the freeze in the first place, use a washer fluid containing glycol ethers as an agent.

3. Faulty Washer Pump Motor

The wiper fluid pump plays a crucial role by pumping fluid to the nozzles. If the washer fluid is not spraying from the nozzle, it’s possible that the wiper pump motor is faulty and the washer system is not getting power.

Diagnosing a Bad Wiper Pump Motor:

To figure out if your wiper pump motor is misbehaving, follow these steps:

  • Inspect Connections: Ensure that all connections are snug and free of loose or frayed wires.
  • Motor Testing: Grab a multimeter and test the wiper pump motor. Check for continuity between the motor terminals. If there’s no continuity, it’s a sign that the motor is likely defective and in need of replacement.
  • Relay Examination: The wiper pump motor relay is in charge of powering the motor. Examine the relay for any signs of damage or malfunction.

Fixing a Bad Wiper Pump Motor

If you’ve figured out that your wiper pump motor is not working properly, replacing it is the way to go. Whether you enlist a professional mechanic or take the work into your own hands, here’s a simple guide:

  • Disconnect the battery: Safety first! Before working with the wiper pump motor, disconnect the battery to avoid any electrical mishaps.
  • Check for power: Get someone to turn on the washer nozzles and probe the back of the connector on the pump. If there’s power, it’s a green light to replace the motor.
  • Remove the old motor: Once located, disconnect electrical connections and remove any mounting bolts to bid farewell to the old wiper pump motor.
  • Install the new motor: Bring in the new kid on the block by reversing the removal process. Ensure snug electrical connections and correct mounting.
  • Test the motor: Before putting everything back together, give the new motor a spin to ensure it’s working like a champ.

We will now embark on a systematic approach that prioritizes efficiency and thoroughness to rectify the issue of windshield wiper fluid not being dispensed.

Step 1: Inspect the Windshield Washer Pump

Carefully examining the windshield washer pump can reveal common problems such as leaks or blockages, which could be responsible for the wiper fluid not coming out. More importantly, by inspecting the washer pump, you could potentially save yourself from future inconveniences.

Here are four steps to guide you through the process:

  1. Start by locating the washer pump.
  2. Check for leaks. If the pump won’t hold the fluid, your old pump might need a replacement.
  3. Assess the pump works. A blockage could mean the fluid isn’t pushed to the wipers.
  4. Test the pump’s electrical connections if there aren’t leaks or blockages.

4. Windshield Washer Nozzle Clogged

When you’ve cleared obstacles, and ensured the windshield washer pump is A-OK, but your wiper fluid is still a no-show, there’s a chance the nozzle is playing hard to get. Debris sneaking into this part or a case of not-so-great washing techniques might be to blame.

If you recently took your car for a wash, this is the most likely reason your wiper fluid is not coming out.

Here’s a quick fix: grab a small wire or needle-nose pliers, and carefully remove any debris causing the blockage. Ensure it’s clear all the way to the windshield washer reservoir.

Once the debris is out of the picture, give your windshield wipers another spin to check if the issue is resolved. It’s a straightforward process to get that nozzle flowing freely again.

5. Blown Fuse

Another possible suspect can be a blown fuse in charge of the washer pump. To begin the detective work, locate the fuse box that houses this important component. Unlike the wiper fuse, the washer pump fuse typically has its own space in the fuse box.

Most times, you’ll find a handy map on the box lid, pointing you straight to the responsible fuse. If you’re struggling to locate it, don’t fret. Your vehicle’s manual is your trusty sidekick, offering guidance on where to find the elusive fuse.

Fix: Replace The Fuse

  1. Use a fuse puller or the designated tool on the box lid to carefully remove the faulty fuse.
  2. Swap it out with a new fuse that matches the amperage rating of the old one.
  3. If, after the replacement, your washers still refuse to work or the fuse blows again, it’s time to consider that your car might be dealing with a more serious issue. In such cases, a thorough diagnosis is in order to get to the root of the problem.
