Windshield Wiper Fluid Not Coming Out: How To Fix?

If your windshield wiper fluid not coming out on one side, rear windshield wiper fluid not coming out, or windshield wiper fluid not coming out frozen. You’re not alone, I had my Nissan Rogue and Honda Accord windshield wiper fluid not coming out, and it was really frustrating.

Not being able to observe while driving is dangerous, and we may end up in an accident.

In this post, I’ll talk about why windshield wiper fluid might not be coming out and how to fix the problem.

I’ll also provide some tips on keeping your windshield wipers working properly.

Why Is My Windshield Wiper Fluid Not Coming Out?

Cause 1. The fluid reservoir is empty or low.

Simply fill it up with more wiper fluid and try again if this is the case. Windshield wiper stores in a separate tank behind the engine bay in most vehicles. Follow these steps to refill windshield washer fluid:

Step 1: Open the hood of your car.

Step 2: Locate the windshield washer fluid reservoir. There is a mark with a windshield icon and the words “windshield washer fluid.”

Step 3: Remove its cap or lid, then fill it up with fluid to the top fill line.

Step 4: Replace the cap or lid, then close the hood.

Cause 2. The windshield wiper fluid nozzle is clogged.

The nozzle on your windshield wiper fluid reservoir may become clogged with debris or insects over time, preventing the fluid from coming out. In some cases, the nozzle may also become clogged if the filter at the end of the hose becomes dirty.

How to fix?

If the nozzle is clogged, you can try using a pin or other sharp object to clear it out.

Step 1: Locate the windshield wiper fluid nozzle. It is located on the underside of the hood, near the windshield wipers.

Step 2: Use a pin or sharp objects, like an ice pick or needle-nose pliers, to clear the windshield wiper nozzle.

Step 3: Insert the pin into the windshield fluid nozzle and then turn it as far in one direction as possible before pulling it back out again. Make sure not to push too hard on the windshield wiper nozzle as it may break off from its mount if you do so!

Cause 3. Bad windshield washer pump

A bad windshield washer pump can cause fluid not coming out. Check and replace a new washer pump if needed.

How do I know if my windshield washer pump is bad?

  1. Check to see if the pump is getting power. If not, the problem could be a bad fuse or a wiring issue.
  2. Test the pump to see if it’s working. You can do this by pouring water into the reservoir and seeing if it pushes the water out when you turn on the wipers.
  3. If the pump is working, but the fluid isn’t coming out, the problem could be a clog in the line. Try pouring a little bit of water directly into the line to see if it clears it up.
  4. If none of these solutions work, the pump may need to be replaced.

How to replace the washer pump ?

Step 1: Remove the windshield wiper reservoir from your car. Loosen the screws or bolts that hold it in place, then pull it out.

Step 2: Disconnect any wires or hoses attached to the windshield washer pump.

Step 3: Remove the windshield reservoir from the windshield washer pump by unscrewing it or prying it off.

Step 4: Connect the windshield washer pump to the reservoir by screwing it on or pushing it into place. Reconnect any wires and hoses that were disconnected during this process.

Step 5: Reattach the windshield wiper fluid reservoir to the washer pump by tightening the screws or bolts that hold it in place.

Cause 4: A blown washer pump fuse

The pump fuse works by providing power to the washer pump. If the fuse blows, the windshield washer pump will not work. It is essential to replace a blown fuse as soon as possible to ensure that the windshield washer pump is functioning correctly.

The washer pump fuse locates in the engine compartment. The fuse box will be either on the driver’s side or the passenger’s side of the vehicle, and it will be near the battery. The fuse for the windshield washer pump will be clearly labeled, and it will likely be a 15 or 20 amp fuse. To replace the fuse, remove it from the fuse box and replace it with a new one of the same rating.

Cause 5: Washer fluid is frozen

When the weather is cold, the washer fluid can freeze and cause the pump to stop working. There are a few things that you can do to prevent washer fluid from freezing:

1.Make sure that you keep the washer fluid tank full. 

2.Use a suitable quality washer fluid designed to work in cold weather.

3.Try to avoid using the washer fluid when the temperature is below freezing.

If the washer fluid does freeze, you may need to thaw it before the pump works again.

How to thaw frozen washer fluid?

You can thaw it by using a heat gun, a hairdryer, or a portable heater. Be very careful when using any heat to melt the fluid, as it may cause a fire.

Buy a De-Icer windshield washer fluid to avoid freezing in the winter.
